Today I rescued my tortured and heavily stained carpet from the scrap heap!
This is how bad it was:
I used my spot-bot with resolve cleaner to work on the stained spot. This is about the best I could get it.
Then, I sprayed almost an entire bottle of resolve on the whole carpet. I scrubbed the resolve into the carpet with a brush, then used a pressure washer with the jet set to a narrow fan pattern. I washed the resolve out using a sweeping motion from the center, outward. After a while there was no more white foam.
Unfortunately, the bad oil stain hadn't been effected much since the initial treatment. It kept a brown color. But, I found something that worked very very well:
Sprayed some on, scrubbed it in, and blotted it out with a paper towel, (wearing gloves!) This cleaned the last bit of the stain out. Final result?
I'm still in disbelief that it cleaned up so well.
