A primary ingredient in curry seasoning, turmeric is popular in Asian cuisine. Also called curcumin, turmeric's bright yellow colour makes it a useful seasoning that adds colour to sauce and rice and flavour to some condiments. Although the colour 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 the turmeric-stained plastic dishes in your kitchen sink.
Make a solution of 125 ml (1/2 cup) cup liquid bleach to 4.5 litres (1 gallon) of water.
Allow your plastic dishes to soak in the bleach solution 30 minutes.
Rinse the 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.
