How do you remove oil stain from shirt if the stain didn't remove after wash?
To remove oil stains you should pretreat the stain with a pretreatment spray or by rubbing it with liquid laundry detergent. Sometimes the heat of the dryer can set a stain. This means that if the stain was not removed after you washed it, and the shirt has dried, it may be stuck there.

How can you remove the turmeric's stain from clothes?
Try Vanish-bar (I don't know if it's available in the States) I had curry stains on a new white Ralph Lauren polo shirt. After reading a variety of posts from a number of different sites, I decided to make a paste of Oxyclean and apply it directly to the stains and let it sit for 15 minutes or so. I noticed that the paste quickly turned the yellow stains red, but I had read that that might happen. So, after 15 minutes of pre-stain treatment, I washed the polo shirt in a washer with hot water, Arm & Hammer Laundry Detergent (with Baking Soda), Clorox bleach, and a scoop of Oxyclean. It worked the first time! No trace of the curry/tumeric stain on the shirt at all!

WHY DOES A TURMERIC STAIN ON A WHITE SHIRT TURN RED WHEN WASHED WITH SOAP?
It is because turmeric contains an acid (tartaric acid), while the soap contains a base (sodium hydroxide). When an acid reacts with a base, neutralization reaction takes place and the stain becomes neutral.
