Turmeric, the primary ingredient in curry seasoning, is popular in Asian cuisine. Also called curcumin, turmeric has a bright yellow color. Its hue makes it a popular seasoning when you want to add color to sauce and rice and to add flavoring to some condiments. Although the color is attractive, it can leave stains on your plastic dishes that can be difficult to remove. Using liquid chlorine bleach is a great way to remove turmeric stains from plastic dishes.
Clean your plastic dishes within two days of when the stain occurred. Allowing them to sit longer than two days could mean the stain won't come completely clean.
Put your turmeric-stained plastic dishes in your kitchen sink.
Make a solution of ½ cup liquid bleach to 1 gallon water.
Allow your plastic dishes to soak in the bleach solution 30 minutes.
Rinse your plastic dishes under warm water to wash away the bleach solution.
Wash your plastic dishes with soap and water.
Repeat the process if necessary, using a stronger bleach solution for stubborn turmeric stains.
