Instructions

1

Use cream of tartar as your cleaning base. Add lemon juice to the cream of tartar to create a thick paste.
2

Apply the paste to the stains found in the microwave. A thick covering should be placed over the popcorn stain.
3

Let the paste sit for 5 minutes. This gives it time to lift up the popcorn stain. Rinse away the paste thoroughly. You may need to repeat the process if the stain has yet to be removed from the microwave.
4

Try a nail polish remover. If the paste is not successful, use a nail polish remover with acetone to get rid of the stain. A small area should be tested first to make sure that it does not damage the interior.
5

Wash with a mild soap and hot water after using either cleaning product. Rinse out the microwave completely to make sure that no traces of the products are left behind.
