Are these supposed to stain? I haven't used them for baking cookies yet, only for frozen food items but they have stained.

Yes, they stain. Very quickly. They still get clean and continue to work great. Mine look like they have been through a lot but cookies come off cleanly and melted cheese slides right off.

I have never used them for frozen food, only for baking things that were not frozen. I have used the sheets for several years and never had any problem with staining. You may have to consider whether using them for frozen food or the type of frozen food was an appropriate use.

I've noticed that they stain when using somewhat greasy/saucy items. I haven't used them for cookies since I use parchment paper when baking cookies. I have multiple types of liners and they've all stained in some way or another. IMO better the liners stain than my cookie sheets.

After a lot of assorted uses, my liners have stained a little bit, but nothing very noticable. They work so wonderfully well, that any lightmarks on them are not at issue for me.

I got these for Christmas and mine stained right away on the second use cooking some frozen fish. Has anyone successfully gotten the stains out I tried the soap and water per instructions but that did not seem to help.

I've had mine for about a year now and no silverware marks so far. They did her some odd round brown stains though and I have no idea where these come from

No I cook all types of gravys in mine all the time and nothing has stained it, it cleans very easy. I'm very pleased with my purchase!

I would return them. They should not stain. Ours did but we had them unite a while and I think it happened because we put them in the microwave.

I purchased a stainless steel 9x13 cookie sheet that I steamed baby potatoes in. S/S seems to mark when you bake/cook in in. Try a small area of "Bar Keepers Friend" powder (can find in larger grocery stores). I only use a small amount with a couple drops of water (make a paste) with a dobie scrub pad. This has worked in every s/s pan I own and it takes off any stain. Remember, only use in a small area at first.

Gosh, I have no idea! I did read recently that the Pam cooking spray I used may have been the cause of the staining. Sorry that's all I know!!

they should work okay (because they do not need to be cured in the oven). however, do not apply too thick because the stain might crack.

I have only used these to decorate cookies....I've never put them in the oven during baking. I find these are much more coarse than sanding sugar. I hope this helps you.

Ive used them for just about every puree you can think of and none of them have stained whatsoever. Best storage containers ive ever purchased and these were my third attempt. Only ones ill use

It looks there is some sort of finish around the edges. A question for the manufacturer I guess. Mine are slightly larger than the cookie sheet and curl up a bit on the edges without problem. I do really like them. Clean up is a breeze.

I do a lot of cooking, and haven't had a stain on them yet. They're also big enough to hold more then one utensil. I love mine. Joanne Kwasniewski

I've not had any permanent stains. They come off with hot water / soap or in the dishwasher.

I have had these for about 6 months, we just mop them when we mop the floor. No stains on ours so far.

I haven't seen any staining at all. And even better my male doesn't vomit after these like he does after chewing rawhide. They're much more expensive but the dogs love them so much better and they are better for them. I have Jack Russells, if you don't give them something to chew they will find trouble for you.

Tomato sauce does stain the bowls though. I've yet to bleach them, but it's said to work.

Hmm maybe contact the company. I have had mine for some time now and they are still good and don't stick to anything. They might have shipped some that weren't good. Try to contact them because it says they don't stick or stain in which mine haven't yet and I've had ours for a while now. See if there is anyway u can contact the foam company and let them know your concern. Hope it helps!
