Alcohol can be safely used to clean stains and soap scum off of your fiberglass tubs. This is a guide about using alcohol for cleaning a fiberglass tub.
My fiberglass bathtub has a nonskid bottom that is terribly difficult to get clean. I have found that the best thing is to scrub it with baking soda. It also seems to stay clean for a long time after I do this. For a little added cleaning power, after it is all scrubbed, I add and scrub a little dash of vinegar all around, scrubbing quickly as the fizzing action only lasts a few seconds. The tub is just gleaming when I get done. It is an amazing cleaner for fiberglass.

S.o.S pad it may not be the best thing to use. But if you have a dark stain in it that will remove it. The stain is worse then the damage the S.O.S pad will do

I have tried many things to get the soap scum off my fiber glass tub, but to no avail, nothing has worked. Is there any sure way to clean it? Thanks.
Will mr clean bath eraser scratch fiberglass?
On your site it says you can clean fiberglass bathtubs with alcohol. What kind are you talking about grain alcohol or rubbing alcohol?
I found the tip. It says plain alcohol or Japanese saki. https://www.goo 9/19563-amp.html
Mom always put her plants in her fiberglass tub to water them. Then she had an unexpected illness and left the plant in the tub, which created a stain that won't come out. Help please.

I've had a cleaning business for over 30 years. This absolutely works. However...use on fiberglass ONLY. Do NOT use on enamel tub because it will remove the paint.
My fiberglass tub has some yellow spots. How can I get rid of them?
What is best way to clean a fiberglass tub? I purchased a house and the tub is very dirty. It is a one piece tub and shower
I used 600 grit, then 800 grit followed by 1000 grit wet sandpaper. I then used a polishing compound to finish off the job. The tub looks brand new now. The sand paper did not harm my tub. So, whom ever is saying not to use abrasives on fiberglass are 'not in the know'.
Oh, it took about 4 hours of hard labor. Not fun, but I got some great exercise.
I have moved into a home with a dirty laundry tub. It is light in weight, so I am thinking it is fiberglass. Does any one in this community of very wise people know how to clean it? It is white if it was clean. This will need a powerful cleaner. Any ideas?
Is there a sure fire cleaning tip for cleaning a fiberglass tub and shower surround?
I have tried Magic Eraser, Kaboom, Scrubbing Bubbles, etc.

I just moved into an apartment with a retro green tub and shower surround. I'm not sure when the last time it was actually clean but it was gross. I mean soap scum and dark grey gunk. Yuck. It was the only big negative of the apt. So today I was reading the suggestions for cleaning and decided to give the oven cleaner and majic eraser a try. OMG!!! It worked great and I didn't even have to scrub it til my arm fell off. Amazing. I'm super happy. I don't mind the "retro" green as long as it is clean....

How do I clean a fiberglass shower?
By Peggy from MN
First, I wipe down my shower after every use with a towel. That keeps the fiber glass shower clean so I only have lightly clean the shower a couple of times a year. I use Bar Keepers Friend that I bought at Home Depot with a non scratch pad available at grocery stores. My preferred brand is made by 3M Co. My fiber glass shower looks as good as the day it was installed and by wiping down the shower after every use it is very easy to keep clean in the minimum of time.
Hair conditioner causes the tub to be very slippery. I clean the tub regularly, no stains, just very slippery. I've tried about every cleaner, suction cups on bath mats do not stick.
How can you get the shiny finish back after cleaning a fiberglass shower pan? I was able to get all the stains out after reading some responses on the best way, but now I'm left with a dull finish and it'll just get dirty immediately without some sort of finish to protect it. Plus it just looks dull and not new looking.

This is a great place to come for help. I've read numerous tips on how to clean a shower, but have never seen a tip on how to clean a fiberglass tub. I need help. Can I use the same tips given for tile on fiberglass tubs?
I have a friend that has hard black specks in her tub, almost like ink spots. At first I thought it was mold that was building up inside the jets of her jacuzzi tub, so I used a cup of bleach and a cup of dishwasher detergent powder, filled up the tub and ran it through the jets for about 20 minutes. That did nothing to the spots. We cannot seem to get them out unless we scrub and scrub, but we also don't want to ruin the surface because it is fiberglass.
Every time she bathes there are more, now they just keep building up. She said she can get them out if she uses her nail then her finger to scrub each individual speck, but then there is a smudge left and we need to scrub and scrub to get that out. We cannot figure out what it is or how to stop it. They aren't grease or mildew spots because they are very hard. We are getting exhausted with this problem and now there must be a couple hundred little spots. I have noticed there is also some in the toilet in the same bathroom that are very difficult to remove too. There are 3 other bathrooms in the house, but they don't have that problem. (The specks are in the master bathroom.)

I have a fiberglass bathtub with the walls and shelves attached. I can't seem to get black mold spots out of the grout attaching the tub to the walls no matter how hard I scrub. Do I have to re-do the grout? Any advice regarding effective store-bought or homemade fiberglass-safe cleaners would be much appreciated.
I have a heck of a time getting the fiberglass clean, the dirt seems to stick to it like glue and scrubbing is useless. It's very frustrating. Thanks so much for your help.

Try spraying with bleach. (04/14/2009)
Bleach is good at killing mold. I would put a little bleach in some water and clean it with that. It still won't look clean, but it should kill the mold.
There is a product called Polyblend Grout Renew. It is a colorant, has mildew preventer in it and is also a sealer, and the bottle says it is stain resistant. I got it at Home Depot in the flooring department, it comes in different colors.
I wanted to do the grout in my bathroom, ceramic tile floor, wall and around the tub, but they didn't have the exact color to match any of the grout, so I just bought the nearest color to it. You apply it with an old toothbrush and while still wet, you wipe over it with a dry rag.
This stuff covered all of the grout which is now a uniform color and made it all look like new, and it actually is stain resistant. I did it about 6 mos. ago and it still looks like I just did it. It is made by Custom Building Products in Seal Beach, California. (04/14/2009)
I bet it isn't Grout but is Caulking instead. Either way, you can use straight bleach to clean caulk or grout. Just pour or spray it on, shut the bathroom door, and leave the bleach to sit for about 20 minutes or so. If it's caulk and not grout, sometimes mold will get into caulking. If it is caulk, it's very easy to re-caulk. They sell a bathroom caulk that resists mold. All you have to do is scrape the rubbery caulk out then re-caulk. Ask at the hardware store, there is lots of cool tips & tools to help caulk a neat line. (04/14/2009)
I use Tilex. If that doesn't work, it's under the caulk and should be removed and reapplied. As far as cleaning a fiberglass tub. I have two products that I use on mine. Bar Keeper's Friend. It's a cleanser like Comet or Ajax and melts away the crud like you wouldn't believe. The second is the Mr. Clean Eraser. Wonderful, wonderful, they will scrub out the remainder of the crud. Blessings! (04/16/2009)
Try using Scrubbing Bubbles. I clean houses and I swear by this product. (04/17/2009)
I also would use a magic eraser on the grout and /or scrub with an old toothbrush dipped in spic n span with water. The fiberglass is frustrating. I once tried a magic eraser on my shower (out of desperation) and now rust stains are so embedded. I think that the eraser sort of micro-scratched the surface. So, try CLR or something like it. Use a scrubby with circular motions dipped in borax or softscrub. I feel your pain! (04/17/2009)
I will add a PS to my post below, Polyblend Grout Renew works with both grout and caulk. (04/18/2009)
Use either natural cotton (like for first aid) or twisted papertowel, place it where the mold is and spray with bleach and leave it until peeking under it shows the black is gone. Can do the same thing with white vinegar. After cleaning, spray the area with white vinegar and leave it to dry. It stops mold and fungus in porous materials (grout) and even painted drywall
I would like suggestions for cleaning fiberglass tub walls.
By waitress from Brick, NJ
I use the Scrubbing Bubbles on mine, after I clean, rinse, and touch up any missed spots I dry it with a towel to speed things up. Then after completely dry I use car paste wax on the walls, it helps to repel the water and soap scum sliding down the drain! I only have to do this once a year, but remember for maintenance do not use a SOS pad or scratchy scrubbers or you will have to re-apply the wax again. Touch ups are fast and easy just apply where needed if it wears off in spots from everyday use. Good luck! I also use shampoo, yes shampoo to clean the glass doors and all of the chrome handles in the tub and shower, rinse well and sparkles like new. (09/13/2009)

The advice about oven cleaner and Magic Eraser was a godsend. I had given up completely on ever getting the shower clean again. After about 15 minutes of the oven cleaner soaking the soap scum came off unbelievably well with the Magic Eraser. After everything was rinsed off I touched up the tough spots with a second spray and wipe and the shower floor was literally as white as snow. Thank you for the tip! (01/08/2010)
I have spine problems and asthma. I've been using shampoo while in the shower to clean the walls a little at a time, and it works great. Tub surround shines so nicely. But for a heavy cleaning job (like tub ring) I am going to try the oven cleaner. I can't seem to keep up with the ring. Any other suggestions? (02/23/2010)
