Stained those leftover containers?

1. Fill almost to the top with water and a squirt of dish soap 
2. Add 1/4 cup of bleach 
3. Microwave the container for 40 seconds, or until the solution is boiling 
4. Allow to rest until the water is lukewarm 
5. Wash out your container and it is as good as new!
