DID YOU KNOW ….
It only takes one exploding mess in the microwave, and it was intended to be wiped clean but it didn’t happen. Now there is a cake like cement substance on the inside. Rather then use chemicals to clean it you can use lemons or lemon rinds.
Add cut up lemons or rinds in a microwave safe bowl, filled half way with water. Microwave it for about 3 to 5 minutes allowing it to steam and condensate. Carefully remove the microwave bowl and wipe the inside clean with a towel.
