If you can find some R-11 it will clean it up quite well (the real R-11, not the R-11 flush)
One time back when we used it to flush burn outs I used always have some on the truck, one time I was changing bearings on a blower and the lady had white carpet, when I was pulling the blower a little bitty dab of grease fell on the carpet, as soon as I touched it it kinda exploded,I mean got bigger, and the lady went ballistic, I took some R-11 and you couldn't see where it ever was
Just a thought, R-11 has come down quite a bit in price,
I have used Non-clorinated Brake Cleaner on my own carpets with very good luck. Spray and soak it up with a towel instantly. Worked good. Better be careful with it, it could melt the carpet if your not careful.
Cheap too ! But be careful.
(What's "gasoila" ?)
If sense were so common everyone would have it !
