Wait wait. Do people not just cook a potato and wipe it down after as cleaning?
My whole life when the microwave needs a wash, you put in a big potato in a bowl of water, like an Idaho, or up to three Yukon gold or baby reds (whatever fits your bowl).. you prick them with a fork, put them in a large soup bowl with like a half inch water, and microwave for 11 min on high.
Let sit for 3 min after it’s done and eat as a baked potato or mashed potato, whatever you like, it’s a potato.
But then importantly you clean the microwave because the steam from 11 minutes of potato loosens all the shit and you can just wipe it out.
You could add a lemon to your potato for the same effect I guess.
(But for real just the water vapor does the job 100% a bowl of water would do the job but making a potato wastes less energy because you are making food)
Ive just seen a styro pyro video where he makes a 20000 watt monster microwave, that damn plate survived him melting steel and titanium on top of it with that monster. I think these plates can survive a little bit of water.
The 790.* model number indicates it was actually manufactured by Frigidaire and then rebadged as a Kenmore. Not coincidentally, that's why they all look alike...
Reminder: Sears/Kenmore never manufactured anything. All Kenmore products are rebadges of other brands and models, without exception. When your dad is ranting about how those Kenmore appliances were built so well and they never did him wrong, but all those new modern GE/Whirlpool/LG/Frigidaire appliances, they're all crap -- he is Earth shatteringly incorrect.
