In this short post I’m just going to give two ways to clean a microwave:
The first is by using a solution of one part vinegar and one part water, 1-2 cups of the mixed solution should be adequate. After putting this solution into a microwave safe container (I almost always use a pyrex or a glass baking dish), the solution needs to be heated for a few minutes in the microwave. I see many sources on the internet suggesting 3 minutes, but I usually do at least 5 and will sometimes repeat heating the solution as I wish.
The second method is nearly identical to the first, but rather than vinegar it calls for water and one lemon. Whereby in this method the lemon juice is squeezed into the water and the lemon is left in the water/lemon juice mixture and heated in the exact same manner as mentioned above for the water and vinegar mixture.
The whole point of either of these two methods is to cause the steam from the given solution to soften any debris within the microwave to make it easier to clean and wipe down. The only thing left to do it the wiping and scrubbing in the microwave itself.
Of course also remember to be careful with the hot liquid while you clean.
