If you’re the type who microwaves ramen without adding water, here’s your stain-fixing hack. Fill the cup halfway with water, add one drop of dish soap and two tablespoons of vinegar, then microwave for 90 seconds. The steam loosens the stain, and the heat makes it slide off like a villain in a cartoon.
Warning: do NOT microwave empty cups unless you want to test your fire alarm’s battery life. Also, if your cup has a metallic rim, the microwave will turn it into a tiny lightning storm—so stick to plain ceramic mugs for this stunt. The result is a steaming, clean cup that smells faintly of pickles, but hey, no pain, no gain.
