Removing grease spots

Rug grease spots. you cannot hide them with your furniture! Especially, if they are in the center of your living room. I tried many professional products. Nothing worked. I had two very obvious grease stains on my WHITE carpet. When they got darker and darker from dampness, I was jsut about to buy new carpet. DON'T DO IT UNTIL YOU TRY THIS! I had nothing to lose-try it on a small area 1st. Isopropryl (rubbing alcohol) poured directly onto the area...or sprayed onto it. Let it sit only for a few minutes. Then, take a dampened sponge with a scouring pad side amd rub firmly against the carpet's grain. I now do not have stains and do not need to buy new carpet.
