Prevent Curry Stains on your Plastic Containers

So many of my plastic boxes have turned yellow after I stored curries in them.
The turmeric in the curries are to be blamed.
No matter how much you scrub it , the stain happily stays.
I was reading about it on the net and found a nice tip for the same.

• To avoid this problem, spray your containers with non stick cooking spray before you store your curries or sambars in them. 

Tada........ you will have clean plastic boxes.
