Take out your lemon, rag, and microwaveable bowl.
Then fill the bowl halfway with water
Then chop the lemon in half
Then take the lemon and SQUEEZE ALL THE JUICES OUT!!!
Then just throw the rind into the bowl
Put the bowl into the dirty microwave
Then microwave for 3-5 min, idk why I did 4:30
Then when you open it up it'll be steamy and all the gunk will be really loose and easy to remove, and it will smell fresh like lemons
Then you take a warm rag (just run it under hot water) and whip away the filth.
And well-ah!! Bright and white!! (except for that stain that we've had forever, oops)
