Another reason NOT to use the programmed popcorn button!! Even the popcorn box tells you not to use the popcorn button. If will vary due to the wattage on your machine, but experiment a little to find the correct time, on high for your microwave. Mine it takes 2:30 and its perfect every time.

Try the Mr. Clean magic erase "sponges". I have found they work on everything, and although I haven't tried it yet on the microwave interior, it might just work on those yellowed walls.

Don't have a clue how to clean it - wanted to say that just knowing there are SO many OTHER people who have burned popcorn in their microwaves makes me feel immensely better. I did get rid of the odor in mine by using Clorox w/bleach spray, but the yellow may be there forever. I am going to try the acetate and then just give up and be happy with a yellow micro. Things could be worse.

I used acetone (from nail polish remover) right after I burnt the popcorn in the microwave..and it did the job!

I read all of these above and thought about getting some Acetone or Cutex. But, I keep Goof Off on hand. Goof Off will damage many plastics, but, the damage is usually limited to that of softening some of the color off non-white plastics. Since the original color of the inside of my 16 year old microwave that I've had for 15 years is white, and tonight, stained yellow, it shouldn't matter what Goof Off does. I tried it on a small area and it immediately cut through the yellow without hurting anything else. So I proceeded with it. Goof Off worked! My 16 year old microwave looks almost like new with a nice and clean white interior. Didn't need to leave it on for more than 30 seconds, and kept clean white paper towels in hand to keep the Goof Off any other plastics of a non-white color.

Easy-off oven cleaner. Awful stains came off after about 30 minutes of soaking.

(format_html)I am writing to thank the person who said acetone free nail polish remover would remove the yellow stain in my microwave oven left after seriously burning a bag of microwave popcorn. She was absolutely right on.

At first, I tried 10 oz. water and three teabags boiled and letting it steam the inside of the microwave, but this did not get rid of the smell nor the yellow stain. I also tried Soft Scrub, 409 Glass and Surface cleaner, and vinegar water. Each of those cleaned the microwave of the first layer of carbon from the burned popcorn, but did not take care of the smell nor the yellow stain. Yellow stain was removed "only" by the acetone free nail polish remover, which I tried in a small spot first because I thought for sure the paint enamel would peel right off. I don't believe everything I read. I cleaned the yellow stain off with acetone free nail polish using lots of cotton balls.

So go at the problem like this:

  1. Clean first with any cleaner you like to get the first layer off down to the yellow stain, this means the door, window, top, bottom, sides and outside vent across the top of the microwave.
  2. Use the acetone free nail polish on cotton balls and go over everything: ie, inside window and inside door, top, bottom, sides.
  3. Wash microwave with soapy water.
  4. Rinse with vinegar water. Once the yellow stain is removed you have removed the main source of the smell. Until the yellow is gone, you will have the smell. Don't use your microwave until you have completed this whole process.
  5. Final step to take is to peel two oranges, put them in a microwaveable dish with water enough to barely cover them and boil for 4 minutes. I stood and watched them boil, because I didn't want a boil over or burned orange peels. Enjoy the oranges while you watch. "Do not open the door." Leave the door closed for 12 hours.

Our popcorn disaster would not have gotten this bad if our smoke alarm, which goes off over a crumb in the toaster, had gone off. We had failed to test and replace the battery. Don't let it happen to you. And, don't walk into another room while microwaving popcorn, stand guard while doing popcorn.

RE: Removing Yellow Stains From Inside Microwave

Being completely out of both oranges and nail polish remover, I tried scrubbing the microwave with "Gumption", it seemed to work fairly well, removed about 90% of the stain. I now currently have a bowl of vanilla essence sitting in there. Am hoping it will help get rid of the smell. Will keep you posted.

To further complicate it, I keep the microwave in the pantry. Now the whole pantry stinks. And I suspect we will be eating burnt popcorn flavoured food for a while. (12/04/2007)

RE: Removing Yellow Stains From Inside Microwave

I had a pretty nasty yellow streak at the back and side of my almost new microwave after burning a bag of popcorn. I tried everything I could think of and then I found this site. I have to admit I was terrified of using nail polish remover. I tried the acetone free one first and it didn't remove it all. I then tried Sally Hansen Maximum Strength on a small area and voila all the stains are gone. What did we do before we had the internet. Thanks so much for a wonderful piece of advice. (06/27/2008)

Removing Yellow Stains From Inside Microwave

Softscrub with baking soda and water should get it out!

By Racing against thimerosol

Removing Yellow Stains From Inside Microwave

I do not have a solution, but let me tell you what does not work so you don't waste your time. I have been researching this on the internet since I burned popcorn in my mom's new $400 microwave. Lots of people like to respond to messages like yours with suggestions that "should" work... or tell you how they "clean their microwave" (in a general sense). But this is not general cleaning -- we are talking about THE YELLOW STAIN FROM BURNED POPCORN. No one seems to have a tested, proven solution.

So... what does NOT work:

1) "Try a little baking powder paste on a wet sponge and apply to the inside walls; let soak for 10 minutes with the door open, then with a wet sponge scrub the inside and then rinse well... let air dry with the door open. You might have to do this a few times if the first time doesn't clean it... also try a few drops of lemon in the rinse water to reduce the yellowing and get a fresh scent... ladydi"

I tried it and it doesn't work.

2)" I read at either ThriftyFun or in Heloise's hints that if you boil a cup of water with a teaspoon or so of vanilla. The steam will help clean the mess, and your microwave will smell like vanilla (instead of burnt popcorn). I've tried this method for cleaning my microwave, and it' gotten everything off."

Well apparently "everything" didn't include the yellow stain from burned popcorn which is what we are talking about.

3) "Baking soda water in the microwave will do it. Boil for 3 minutes and wipe it out. Jane"

No it doesn't.

4)"Put a bowl of vinegar in the microwave and turn it on so that it will steam, probably 1 or 2 minutes depending on your machine. Let it sit in there for 10 minutes and wipe it out with clear water. It seems to really help. Also make sure any removable parts are run through the dishwasher or washed well. Hope this helps, Susan"

It didn't help.

5)"GRANDMA'S TRIED AND TRUE VINEGAR RECIPE
5T Baking soda, 3 drops hand soap or liquid dish soap, 4T Distilled, White vinegar"

Obviously not tried and true for burned popcorn.

6)"I clean my microwave like this: Put a mug half full of water and stir in 2 spoons of baking soda. Put this in the microwave and turn it on to boil the water for about ten seconds. The steam will help loosen all the splatters. Carefully remove the mug and clean with baking soda/water paste and a sponge until clean. Rinse well."

I don't care how you clean your microwave... have you cleaned burned popcorn?

7)"I put a cup of water with lemon juice in it..in the microwave for about the time to make a cup of tea.. then let it sit in there for about 15-20 min...and steam clean the microwave..not only will it get the smell out it will also make the food that has splatter just wipe right out."

There is no "food that has splatter" ... it's a yellow film which seems to have molecularly bonded to the microwave.

8)"I did the same thing w/lemon juice and water but I did not put it in a cup/mug. I soaked a wet hand towel in water, put a little lemon juice on it and warmed up the towel. It steamed up the microwave, loosened all the gunk, and gave it a fresh lemon smell. I used the same warm towel (or rag) and cleaned the microwave. This is what my book "talking dirty" said to do ,Smile"

I did the same thing and it burned the towel, did not really create much steam at all, and did not clean the stain whatsoever.

So... there you have saved yourself much disappointment. Don't bother trying any of those suggestions.

The question is this:

Has anyone out there actually had this same exact problem (YELLOW stain from burned popcorn), AND solved it successfully? In other words... your microwave was yellow on the inside due to burned popcorn, and now it is white again, and you accomplished it through some method that you can pass on. If so, how?

I also have the yellow stain. I have tried many cleaners. I even got desperate and tried an S.O.S, pad on part of it and that didn't even help. I think that maybe it is stained forever :( The lemon water tricks did work for the smell but not the stains. Keep posting if you find anything that DOES help the stain.

I used Soft Scrub with bleach and it worked. Just spray some on, leave it on for 10 minutes, scrub if off hard and it will come off! Now I don't have to kill my friend who put the popcorn on for 4 minutes --seriously, who puts it on for that long? Anyway, we're friends again, and just because it came off doesn't mean I'm not going to do that same thing to his microwave. (I'm going to put it on for 10 minutes)

Removing Yellow Stains From Inside Microwave

Well I have read most posts on this site regarding the Yellow Stain. Well My lovely wife last night tried to cook our kids the infamous popcorn for a light snack. In the midst of the crazyness in the house, she pushed the "potato" button instead of the "popcorn" button. to make a long story short, my 4 year old daughter dialed 911. After I arrived at the house, I noted that the microwave was stained yellow!! It seemed permanent. I had not read this site until the next day, but this is what I had done to remove the yellow stain. Firstly, I got a spray bottle with 100% bleach. Sprayed it and let it sit for 30 minutes. Then, wiped out. Sprayed again, let it sit another 30 minutes and wiped out. I used white towels mostly through the process as then I can see actually how much of the yellow I am getting off. Next I scrubbed with an SOS pad, however this did not seem to help. SO I washed with hot water and soap, then did the bleach process a third time. Each time I did the bleach, it removed some of the stain. Once more I did the bleach process and let it sit over night. As my microwave is a built in above the stove, I did not use any of the equipment until I cleaned out the bleach the next day. I would say that the stain is 85% gone. Now my biggest problem is the smell that works it's way into the food items that you cook after. Being that this is only the second day, I will try various methods of removing the smell/taste. Did I mention that my wife is an (b)Executive Pastry Chef (/b) for a well known resort in Monterey California. Well I hope that she NEVER serves popcorn to her guests!!

I just tried the Soft Scrub method and it did work for the yellow stain on my microwave - also caused by overcooking popcorn.

It takes several iterations to get it all. I wiped the Soft Scrub w/ Bleach on; waited 10-15 minutes and then scrubbed with a sponge. Then I left the soapy stuff on; added more Soft Scrub; repeated the process. I did this about 10 times and it did work to significantly reduce the stain.

By Peggy

Removing Yellow Stains From Inside Microwave

Which Soft Scrub with bleach? The gel?

To "Here to help" - My old microwave took over 4 minutes to pop popcorn but my new one takes only 2. No matter how many times I've told my teenage daughter 2 minutes she never listens. This is the second time she burnt the microwave. First time I caught it before it was set on fire. Second time I wasn't home and she let me find it the next day.

I tried Clorox Wipes and also sprayed Clorox on them. I put the wipes up like wallpaper on the stains around the microwave. They were pretty wet. Then I put a cup of water in the microwave and turned it on for 30 second intervals, checking and wiping each time. The yellow is not entirely gone, and I doubt if it ever will be, but it is better. I had to do this about 8 or nine times.

Removing Yellow Stains From Inside Microwave

Hi Adam, hope this helps, my son also burnt my microwave, and I also tried most of the suggested remedies and nothing worked(not sure I would ever put bleach inside my microwave and then cook food in it). I cleaned the inside with Enjo marble paste (which is non abrasive) and then sat the clean microwave in the sun for 2 days(not at night) and the microwave was white again after 1 day, but I put it out again to make sure. Good Luck.

To get rid of the odor: Try the air fresheners that neutralize odors. Spray on paper towel or cotton and leave in microwave or wipe sides with it.

By Cmjake

Removing Yellow Stains From Inside Microwave

This WORKS!!!!!!! Use Cutex "Quick & Gentle" nail polish remover(Acetone). Put some on a paper towel and wipe the area stained....You'll have to change paper towels frequently..But No hard rubbing...Ours looks like new ..now to work on the smell!!

By Yellow burnt popcorn cleaner

Removing Yellow Stains From Inside Microwave

OK, so I am thrilled to know I am NOT the only one who has burned popcorn in their microwave!! Initially, I was concerned with the smoke and putrid odor. First, I opened all the windows and turned the fan on venting the smoke from my apartment. Next, I wiped the oven out with the dishcloth and Dawn Detergent (several times) to no avail. The odor remained and so did the infamous 'yellow stain'. What did I do? I closed the door on the microwave and went shopping! (That did NOT help!....but I DID find the cutest pair of shoes on sale!)

Next, after the smell became unbearable, I wiped the inside of the oven with vinager. Didn't do much.

Finally, I hopped on my handy-dandy computer and found this site.
I tried the "CUTEX Nail Polish Remover" and it actually DID help quite a bit to remove the yellow stain. I've only done it once at this point, but there IS a dramatic difference! (Approx. 80%)

I wiped the inside down again; this time with straight lemon juice (leaving the interior fairly wet) and then placed a microwavable measuring cup with about 1/4 cup of straight lemon juice in it and allowed it to boil for about 2 minutes creating steam that has covered all inner areas.

That has been sitting for approximately 15 minutes and I just checked it. The odor is still faint, but not nearly as potent as before.
So, I will let it sit longer and see what happens. I am confident the odor will eventually disappate in time. The faint yellow discoloration is tolerable.

I believe if you are going to have any success at all, you will need to attack the problem immediately, otherwise, (especially with use of the oven) the odor and yellowness will penetrate and become permanent.
Good luck and if anyone comes up with something that is more effective .....PLEASE.... post you suggestion! Thanks!!

Removing Yellow Stains From Inside Microwave

The exact thing happened to me just tonight. I used the above suggestion to use nail polish remover and it worked like a charm. How safe THAT is, remains to be seen. Now, the smell of burnt popcorn is still in the entire house, but I am hoping that will disappate over time. I am going to leave it open over night, then cook a cup of vanilla and cinnamon with some water...and we will see what happens

By Betty

Removing Yellow Stains From Inside Microwave

Burned the popcorn! Lots of smoke...Immediately clean out with baking soda and it looked good except the yellow keeps coming back...I clean it again each time and it is better. The odor is another thing...tried the lemon...didn't work. Now I am going to try the vanilla, vinegar and baking soda water in that order for the smell. While looking on here for an answer, I burned lunch on the range!!!! This is what I do. My husband gets soooo upset!

Removing Yellow Stains From Inside Microwave

Buy a bottle of 100% acetone and rubber gloves(from drug store or beauty supply store). Pour acetone into a spray bottle. Spray generously on the inside top, sides and base of microwave. You will see the acetone liquid turn yellow and puddle as the surface sprayed becomes whiter. Immediately wipe the liquid with a dry paper towel, since the acetone tends to evaporate quickly. Repeat the steps to remove another layer of the yellow burn stain. You can also spray the liquid acetone on the microwave door, but if it is a "built in", be careful not to get acetone on any painted surface. It is normally used to remove acrylic nails and fingernail polish, so it can damage painted surfaces, but won't damage plastic or glass (i.e. your microwave body and door).

By Lisa

Removing Yellow Stains From Inside Microwave

Acetone works great. Wiped right out without any problem. The inside of my microwaved was severly yellowed from burnt popcorn. I tried soft scrub with bleach and it didn't even phase it. However, the yellow stain easily wiped out with acetone. Looks like new again. One thing -- I stopped using my microwave immediately after the popcorn mess until I got it cleaned up. Not sure if continuing to use it would have cooked in the stain. I applied (using rubber gloves) with paper towel and rinsed with water and later lemon juice. However, I like the idea of using a spray bottle; it does evaporate fast. Now working on smell which lemon juice seems to be helping.

By PaulinMI

Removing Yellow Stains From Inside Microwave

I had the same problem with my microwave. Our 12 year old put a bag of popcorn in for 4 minutes (didn't know there was a 2 minute popcorn button) Anyway, it is built in above the stove so not that easy to replace. The acetone (Cutex) is the only thing that worked. I was leary about trying that but we did not use for several days after and I wiped it clean with vinegar and then boiled the water and lemon juice in there. Looks new again. It was only 3 months old before this.

First of all...its soo great to know that I'm not the only one who's had to deal with this issue...anyway i tried the nail polish remover and it REALLY DOES WORK!!! I ran out of nail polish so I'm going to get some more tomorrow and clear up the remaining stains.

I was skeptical but desperate and I'm glad to say it worked!!!

The smell on the other hand.....I'm just going to have to wait it out : )

Well my mother burned the popcorn in the microwave and I walked right into a cloud of billowing smoke. I managed to clean the microwave but can't get the smell out

Removing Yellow Stains From Inside Microwave

My grandson recently burned some popcorn in my microwave. I was able to scrub almost all the yellow stain out, but it still had a distinct smell I couldn't get rid of. One day after peeling an orange, and on my way to the trashcan, I decided to put the peels in my microwave instead. I put them in a bowl and just left them in there all day....removing them only when I needed to use the microwave. It was quite an improvement so I did it again the next day with fresh peels. After about 3 days of doing this I could no longer smell the burned popcorn. It might work for you too! I think I realized the popcorn was burning fairly quickly and snatched it out of the microwave so I'm sure the smells I was dealing with were moderate compared to some!

By Grandma Margie

Non-acetone fingernail polish remover and a little elbow-grease did the trick. I will never (try to) eat microwave popcorn again.

By Monika

The non acetone nail polish remover got rid of the horrible yellow stain in my microwave and it didn't even smell too bad although when I was finished I wiped everything clean with hot water and soap.

Thanks for the tip, it was a great solution!

By elrtgirl

Removing Yellow Stains From Inside Microwave

I have joined the club more than once. Most recent incident was a hot pocket. Big mess! Lots of smoke! I think I have conquered the stain problem. I sprayed the inside of the Microwave with Tilex Mildew and Stain Remover, (a liquid), and waited about 1 hour. I attained results right away so repeated the process several more times wiping it clean after each application. After that I repeatedly boiled water to make steam which loosened more stain. I did notice that once I began using the microwave for cooking/heating food, the stains seemed to return in places so I repeated the Tilex process. One trick that I discovered is to put a small amount of liquid dish detergent on a sponge an squish it to make foam. Then add Tilex to the sponge and squish some more. You can now daub the foam in the sponge onto the stain where it stays in place instead of running off into a puddle. This works well for the stubborn "spots". As for the smell, it gets weaker each time you use the oven, but it will take quite a while. Before I burned the Hot pocket, I burned popcorn more than a year before and had totally forgotten about any odor until I did it again. Your microwave will never be like "new" again, but you can probably make it quite acceptable.

Thank you so much for your suggestion. The nail polish remover works like a charm! The same thing happened to our microwave where it turned yellow inside from a popcorn mishap. I gave up on trying to clean it. I tried elbow grease, fantastic, and softscrub. Then 2 months later I thought I'd attempt it again and I found this website. Thanks!

Removing Yellow Stains From Inside Microwave

Well, on my birthday last night, my fairly new boyfriend/roommate decided to cook popcorn. I usually watch over him in the kitchen because he doesn't seem that bright but I thought I would give him the benefit of the doubt and said to myself "How can he screw this up, it's only popcorn"?

Needless to say he almost burnt the house down! Now my "like new" condition microwave looks like I couldn't even give it away to the salvation army or goodwill! Can't get rid of the smell or the stains but I did pack his stuff up and threw him out! Also caught him leaving the stove burner on a few days ago after he cooked himself a burger.
He was cute, but not that cute!

I have tried almost everything for my microwave. The thing that works the most but not completely.. is nail polish remover. it really works well. Now I need to get the smell out I haven't tried it but my dad said "Bake a cake in there." I don't know if he was for real or not !!! lol

By Meagan

Removing Yellow Stains From Inside Microwave

To get rid of the smell- half cup of warm water and half cup of vanilla extract mixed. Heat until boiling. turn off and DON'T OPEN overnight, or 12 hours. It sees like a long time, but it's worth it. I know how bad that smell gets!

My gf recently burned some popcorn by accident, and luckily I found this site! Her landlord is a creep when it comes to inspections and wanting to snatch up the security deposit. Well, we tried nail polish remover right away and it WORKED GREAT! The yellow stain was gone right away. Thanks a ton!
