How can you stop your microwave from going rusty inside?

Question

I bought my daughter and her boyfriend a microwave couple of years ago. They are not the most careful pair and they have very little respect for anything, even if it costs a fourtune, even if they buy it themselves!! The inside has gone extremely rusty, with great dollops of peeling hanging from the roof-yuk!! I can't imagine how they can bear to eat anything cooked in there! I figure that it's the condensation that has caused this and I believe you should mop up any moisture b4 closing the door after use, but they obviously haven't done that.
I'm not finacially well off and although I would like to get them a new microwave I can't see that I can afford one with a stainless steel interior, is there a way to prevent this spoiling to another microwave?
Please don't advice me not to get them another ect ect... I've battled for years & years with my daughter over her way of thinking ect ect, now that she doesn't live with me I choose to have peace with myself and her by saying nothing.

Do you lot ever read ALL that's written b4 you give your answers?

I'm sure I asked how to stop it rusting, and yet I've had advice on the one thing I asked NOT to be counselled on, and advice on saving the already ruined one, and even an idiot suggesting I'm mistaken about the interior of microwaves!!!!!??

PLEASE, can anyone tell me HOW to stop another microwave from going rusty inside?

Answer 1

I clean the insides of mine all the time and it's 5 years old and doesn't have any rust. Maybe they need to clean up their act to.

Answer 2

You(they) could clean it out thoroughly and sand away the rust and spray paint it with an epoxy based paint but for a little more than the cost of a can of paint you(they) could buy a new one for right around $50 +- $20.

If a microwave is wiped out with a damp cloth with a little dish soap at least once a week and especially after a spill you can prevent rusting. When certain things are heated up in the microwave there is steam and moisture condensing on the walls and top and floor of the unit and if that is not wiped away it will eventually start rusting and if that is left to happen on a regular basis you can get a really messy looking oven.

Kenwood Stainless Steel Microwave

Answer 4

THE METAL PAINT WILL SOMETIME START TO PEEL OFF ON THE INSIDES OF A MICROWAVE AND I BELIEVE IT IS DUE TO THE HEAT. SOME WILL DO IT AND SOME WON'T. THERE USED TO BE A PAINT LABELED FOR THE INSIDE OF MICROWAVES AVAILABLE IN LITTLE DAUBER TOPPED BOTTLES. CAME IN CREAM OR WHITE COLOR AT AN OUTRAGEOUS PRICE FOR WHAT YOU GOT. ANYWAYS, CLEAN UP THE RUST SPOTS AND REPAINT WITH A MATCHING PAINT, ACRYLIC LATEX SPRAY SHOULD WORK FINE I THINK. IF IT DOESN'T IT WILL FALL OFF SO TRY ANOTHER TYPE. I WASN'T AWARE THEY MADE ANY INTERIOR LINERS FOR MICROWAVES OUT OF PLASTIC. I THINK THAT WOULD SURE CREATE SOME PROBLEMS WITH RADIO FREQUENCY RADIATION. LESSEE. IT HAS TO BE NO MORE THAN 5 MICROWATTS PER SQUARE CM TO BE LEGAL TO SELL, AS I RECALL. THAT IS A FEDERAL LAW. SOME STATES ALSO HAVE FURTHER REGULATIONS ABOUT MICROWAVE OVENS.

Answer 5

No disrespect, but I'm having a hard time believing that is truly rust in there. Metal causes sparking--actually arcing, that's why we can't put metal pans in the microwave.

My mother's micro had red spots. They were stains from some red sauce that had splattered. Since her eyesight is so poor, she didn't notice and by the time I found it, it was into the oven wall material......a plastic.

Now, my dear love isn't good about wiping out the micro to remove moisture and we actually got mold up in the seams (hang my head in shame). Chlorox took that right out.

Anyway, if you insist is is rest, first start with Bon Ami, it is a scratchless cleanser. If that doesn't work and you feel you have nothing to lose, use ZUD cleanser and maybe one of those Mr. Clean Magic Eraser sponges.

Answer 6

Microwaves DO rust depending the manufacturer. The coating on the metal interior is not substantial enough to resist the rigors of condensation and other liquid cleaners over time. The oxidation process will certainly happen faster if the owner/user doesn't practice at least basic oven hygiene. The rust will soon become a bio-hazard. I would get rid of it and purchase a microwave with a stainless steele interior, and emphasize the absolute necessity of cleanliness. You would not believe what filthy conditions in microwave ovens I have seen in the last 25 Years!

Answer 7

I'm not real knowledgeable on the new microwaves, but I've never heard of one rusting or one that's stainless steel in the inside. Microwaves and metal don't get along, it's like mixing oil and water, it just don't work.
Could the "rust" actually be food buildup that's growing weird things? I tend to believe that above the 'rust' and a good scrubbing should take care of that. Try scrubbing it and see if that isn't the problem. But only if you want to put forth the time and effort.
And far be it from me to tell you to buy them another. If they don't take care of what you have so kindly bought them why would you want to put out more just to see it trashed? I wouldn't. And I don't. My daughter is just about the same way, and I don't replace anything she and her hubby tear up regardless of if I bought it for them or not.
The only exception to this might be her car, which is also mine. I wouldn't replace it, but if they start tearing it, I'll jerk it right out from under their azzes in a heartbeat if not faster.

Answer 8

i believe the rust comes from 2 things. which i don't remember reading in the directions when i got the microwave. i wish i had known about this before so i could have saved my microwave. just need to change your habit after using the microwave.
1, the steam that comes from cooking and making hot water for coffee and tea. you take the cup out and shut the door. there is no release of the steam. so it stays inside and causes rust. Need to leave the door open. 2, after you clean the microwave you need to leave the door open, too. over time, not leaving the door open for a short time to air out the rust builds up. i have had my microwave for about 20 years now. i noticed the rust problem about 3 years ago starting. i couldn't figure it out for the longest time. then finally, it came to me. what had changed over the past 3 years was that i was heating up water for tea and shutting the door after i took the cup out.. before i used to heat water on the stove. to save time in the morning i started using the microwave. its just like when the steam has no where to go in the bathroom, you start to get mold. open the window if you don't have a fan. So, everyone needs to start leaving the door open when you are finished with the microwave for a short period of time to make its dry in there before you close the door. now it looks a bit bad. i still use it until i can get another one. also, keep up with wiping it out regularly, (food and liquid spills) they get stuck and then you scrap off and scratch the paint, where it easy to start the rust. if you are top of it the inside will always look new until you ever decide to replace it. Good luck.

Answer 9

I have never heard of a microwave that has gone rusty inside. If it is cleaned up really well and still has the rust; i would contact the company that makes it. They can probably help with the problem.

Answer 10

Yes, rust inside your microwave is extremely dangerous. Dispose of it immediately, and wear a lead apron if you can get one. Otherwise just don't hold it too close to your body.

Answer 11

I have had a few and all gone rusty inside always wipe them out after cooking and leaving the door open but it still happens
