Pyrex Stains - removeable?

[swestoyz]

Hey Guys ~

Quick question I wanted to throw out there. Here are two great examples of Pyrex pieces that are in wonderful shape - EXCEPT - the stains. I've tried some simple methods (gentle SOS pad scrubbing) and it didn't do the trick. Are these pieces savable - or should I take them back to GW?

Yup,

They can be saved. I have found that pyrex, when run through the dishwasher with good detergent (European detergent is best, but US will do) gradually cleans up. If you are in a hurry, the ceramic stove top pads GE sells together with Ceraclean (or the generic equivalent) will do the rest.
Takes awhile, but I have restored worse, without scratching.
Gosh, those are pretty colors.

Ben, those are just beautiful. I don't believe I have ever seen the red before. I wouldn't put them in the dishwasher though as it does fade the color over time. My suggestion would be to use some oven cleaner on them. Bar Keepers Friend might also help. Apply and let sit then use a soft scrub pad. Soft Scrub cleaner might also help. Terry

I have

several pieces of the red.

I have found that a paste of baking soda and water, and slow scrubbing by hand with my hand works well.

Good luck, they are beauties.

Oven cleaner will strip that baked on grease and grime right off. Spray and allow it to "dwell" for a while, then you should be able to literally wipe it away.

Easy-Off in the BLUE can (no lye, fewer fumes). Cleans Pyrex and Corning Ware Pyroceram.

Follow up with Bar Keeper's Friend.

Try ceramic hob cleaning paste/cream and a microfiber cloth.
It should remove the stains without scratching the surface.

If you are dishwashing them be very careful to select a good detergent. Do not use one that's packed with harsh chemicals. The higher end detergents tend to rely more on a cocktail of enzymes than on nasty chemicals and are much more gentle on glass/ceramic.

Both chlorine bleach / Sodium hypochlorite are not particularly good for them either.

Make sure that any detergent you use says that it's glass-safe.
Some of the older and cheaper forumulations can etch glass quite badly over time.

I hope that you don't mind if I chime in...

I use Corning Cleaner, available at the Corning outlets and also at Amazon. You might need to use a little elbow grease in addition to the cleaner, but it works well.

WOAH - thanks for the response guys! I'll keep you guys posted with the results. Thankfully these pieces won't become GW fodder.

I have used ammonia to clean old fashioned gas stove burners in this way: dampen paper two or three layers of paper towels with ammonia and put it on the area with the baked on grease; then put it all in a plastic bag, close the bag, and the next day, the baked on grease will usually just wipe off. It takes a while, but it is cheap and does work. I think this would also work on your Pyrex without damaging the colors. I am anxious to hear how successful you are.
