Help!
I'm short of clothes as it is and I've machine washed a t-shirt without realising I've splashed some kind of greasy blotches down the front.
The t-shirt is plain so I cannot disguise it as "part of the pattern" 
T-shirt is now dry (in the hopes that the stains would magically disappear - it sometimes happens!) but they are very much still there.
How can I remove washed-in stains?
