I own several Pyrex, glass measuring cups that will not come clean. They all have a film on them. I have tried scouring by hand and running in the dishwasher. I have tried bleaching them, letting them sit overnight in various soaps and bleach, etc., but no luck. I specified they are made of glass, because I'm not sure if Pyrex makes only glass products.
I thank you for your help.

Thank you for your ideas ! I really do appreciate
them. The cups are so useful but they look terrible.
Thank you again.
I can agree with everyone above using vinegar. I use those Mr. Clean pads. Not only does the film come off, but the brown cooking stains that Pyrex gets sometimes comes off like a charm. good luck to you.
It is entirely possible that the glass is etched from your dishwasher. If this is the case, it won't come off. I wash my glass measuring cups by hand.
I tried soaking my glasses in vinegar. I soaked them in straight white vinegar for 3 days! And the film still didn't come off! I wound up replacing them and now I wash all my glassware by hand and never put it in the dishwasher.
Did you try adding a bit of baking soda w/detergent in the dishpan?I agree if they're etched from a dishwasher they might be doomed. Also try a paste of baking soda and detergent. This combo works great on burnt stove drip pans or oven drips also.
This isn't very "green", but oven cleaner isn't a bad idea. I clean Pyrex casseroles every few uses with it, because they always get a build up from cooking. Just spray them, and leave overnight, then wash them several times. Works for me.

This isn't very "green" but have you tried Oven Cleaner? I use it for my Pyrex casseroles that get a build up every now and then from use, and it works fine for me. Spray on and leave overnight, then wash thoroughly, first in soapy water, then in clear water. Best of luck.

I take all my glassware that have film on them and soak them over night in a pan of water and a big scoop of oxiclean. in fact, I use the generic brands. I learned this tip from a bar bartender. Good luck, it works for me!
Pyrex makes a lot of things that shouldn't go in the dishwasher. The finish comes off leaving them looking filmy. The glass is etched. This includes the writing on glass measuring cups. If you've been running them through the dishwasher, this might be the problem. They're clean, they just don't look it.
Try soaking them in vinegar (as previously suggested) and baking soda in a dishpan. Fill them up with white vinegar and then sprinkle in lots of baking soda. I do this when my dishes and glassware form a non-etched film and it works quite well. By using a dishpan, when the baking soda starts to fizz, the overflow will stay in the pan.
I have cleaned both Pyrex and Corningware, with years of baked on stains nothing else removed, by making a paste of baking soda mixed with dishwashing liquid. I make it thick and use a slightly damp sponge to scrub. use moderate to firm pressure. It never scratched anything I used it on. So, it's worth a try!
How do you remove burned food from Pyrex? It is a sugary glaze that burned on to the Pyrex.

I find that the easist way to clean baked on food is to use a dryer sheet and hot water. I let the dish soak with the softener sheet while I do the rest of the dishes. It usually comes clean without alot of effort.
"Barkeepers Friend", at any grocery store, near the Comet and Ajax cleansers. Works Great! Good Luck
Hot water, some dish soap & baking soda. Let of soak for a little while, add a little vhite vinegar, let sit another 10 min. Put a little x-tra baking soda on your sponge when cleaning, if needed.
Pretty much the same as other posters. I always simply fill with super hot water and some dish soap, soak overnight and then use a Scotch Bright pad. Rarely does it ever take any sort of elbow grease to get it all off on the first try ;-)
Soak it with automatic dishwasher detergent and water. That stuff dissolves everything. Before I had a dishwasher I always kept a small box on hand for such purposes.
My mother in-law worked in restaurant where they soaked pot and pans with baked on food using spic n span. Just sprinkle it on then add a little water to cover it and let it set.
Although it isn't as 'green' as baking soda or vinegar, I use a small amount of straight bleach for a burned-on area. First I remove as much as I can and then only add enough bleach to cover the spot.
I would have to agree with everybody here on the dish-washing detergent. I soaked the dish in cascade dish-washing detergent with water for an hour which softened all the grease up and then I scrubbed all the grease away with a brillo pad. The dish came out looking brand new. It was all messed up before. It had all types of spots all over it. It had been like this for atleast a month. I thought it was done, but I wanted to give it one last chance before I had said the grease settled in. And it didnt. It all came out. Give this one a shot!
OK. This works great, I had a dish soaking for days but nothing happened. But, then I added water until the stain was covered. Then put in a teaspoon of salt and a healthy squirt of dish soap (I used fairy brand). Then I microwaved the concoction for 3 minutes on high. The whole thing scrubbed off easily with the scouring side of a dish sponge.
I had baked on food for years on my pyrex 9 x13 and read here that Mr. Clean Erasers would remove it. So $3.79 later I still have baked on food. Didn't even touch it. Don't waste your money save MR.Clean for the bathroom. Now on to Easy Off oven cleaner and give that a shot. I'm doing it outside however, that stuff is toxic!
I put a good amount of baking soda and small amount of water, set on low on the stove, it gently "simmers" it out, have done hundreds of times, especially on dishes with burn stains from garage sales. As soon as you take it off, dump the water and start rinsing the leftover gunk out with Dobie and water.
Do you have crusted stuff you want off the bottom of a Pyrex pan? Just fill it halfway full of water, put in about 1/4 cup baking soda, let come to a boil on the stove. Turn it off, forget about it for about 2 hours. Go back, and voila, it's clean!

I believe this tip is only for Pyrex (glass) sauce pans (meant for stove top use) NOT baking dishes or casseroles. Do not treat your baking dishes in this way, they could shatter. - Susan
I use bleach (!/2 Spoon) and a dash of dish soap let set over night let new no scrubbing at all it works. The Miracle maid electric Pan I am having a hard time cleaning the inside. Pan is 38 years old. Cooks good.
