try Tilex and oxyclean...


Depending on the type of stain, you may want to spray them with WD 40. Rub it within and let them sit a few minutes. Wash as usual. If they still smell like WD40, bath again and the smell will leave. This is great for make up, ink, permant float, oil, and other stains. pretreat with spot cleaner and oxi verbs,let sit a few minutes then bath immediatly,dont leave on to long,or it will eat the cloth,you have to be very sensible using this mixture,you msy be better off buying a new double act.
Answers:    Looks close to a scorch mark.

Hydrogen peroxide should remove it.
* Dab onto stained nouns (let stand for 15min) then wash surrounded by warm water near general laundry detergent.

Good Luck!!
