How to clean burn marks in a microwave

DS decided to cook popcorn in the microwave without the revolving plate in it. I now have yellow burn marks in it.

We've tried oxi magic, ceramic stove top cleaner, and magic eraser on it. Still have scorch marks in it.

Anyone have any suggestions on getting them out?

Arson and new microwave are not answers BTW.

What is the plate made out of?

Depending on what it's made of, I like Bar Keepers Friend (powdered version) for tough jobs.

Edit: I see it's not the plate that is scorched but the inside of the microwave. Sorry about that! I would try some Bar Keeper's Friend...good luck!

Just paint over the burn marks. But be sure to use a lead-based paint so it won't absorb the radiation when the microwave is in use.

Hmm, looks interesting. Never heard of that but I will give it a try.

I need to see if I can get it locally.

Thanks!

I can buy it in my area at places like WalMart, Target, Home Depot, Grocery Stores etc

Barkeeper's friend is my go-to when all else fails and it has yet to disappoint. I just used it the other day to clean dye stains out of my bathtub (left a pair of new bike shorts hanging there to dry after a ride in the rain.. didn't realize they'd bleed).

It comes in both liquid and powder form... the liquid is better for things that can't tolerate any amount of abrasion (ie: I use it on my glass-top stove). They're both awesome but the powder seems to be a stronger cleaning agent so I'd go with that if you can find it. I've bought both varieties at Walmart.

If the plastic is actually burned and discolored you might be out of luck but if it's just a surface scorch this stuff should do the trick.

Good luck.

just live with it. the burn marks are permanent and will create hots spot in the microwave from this point forward no matter what you try to do.

DO NOT FOLLOW THAT ADVICE. Lead can be toxic because microwaves steam up, and lead paint offers no protection against radiation absorption.

Use regular lead-free white acrylic enamel or urethane paint (not latex paint -- not good in moisture) with non-toxic titanium oxide pigment. Virtually all white paint made in the past 30 years is made with titanium oxide pigment. There is a paint mad especially for painting microwave interiors, including the part above the mica cover, but it's not necessary.

Microwave frequencies are way too low for lead oxide pigment to shield agianst its radiation better than any other metallic pigment -- you're thinking of x-rays and gamma rays,, and actually a lot of pure metal in paint would probably cause the microwaves to heat it up.

I would not try any harsh chemicals if the microwave interior is plastic because they could weaken the plastic and eventually make it crack. However a crack won't cause microwave leakage because there's steel liner behind the plastic. But if the interior is porcelain-coated steel, try bleach, peroxide, or oxygenated cleaners overnight to remove the stain. What Kristin said about Barkeeper's Friend cleanser -- you don't even have to scrub for it to work sometimes because it contains oxalic acid.

I don't understand why anybody would use a microwave without a turntable that was already in place. And even if he didn't, wouldn't the dish that everybody puts under food in the microwave catch most of the liquid?

we keep a silicone mat in the mw which catches spills and such and makes it so much easier to clean

He was cooking popcorn and I figure that since the bag was not on a turntable, it pressed up against the wall of the microwave.

He's 11.

This post brought me great joy

TS, if you use Barkeepers Friend, be sure to wipe down the microwave thoroughly before you use it again, IIRC it has bleach in it.

Edit: It has oxalic acid in it. I would still wipe it down pretty good before putting food in it.

DH did the same thing . . . and he is NOT 11. I tried EVERYTHING to get the burn marks and the smell out. 6 months later the "burnt smell" is gone (finally) but the marks remain. Considering this was a new $600 microwave, I wasn't up for purchasing another one. Sadly, I have learned to live with it. Let me know if you find any great solutions.

Yeah, this was in a built in mw. House was built less than 2 years ago.
