I've spilled a half-gallon on carpet and got it out. The best way is to remove as much as possible by scraping the bulk off the surface when still wet first. Then scrub with soapy water,blotting up with clean towels as you proceed. The next step is the most important. You scrub not harder,but lighter and lighter the top surface only. What is under the surface stays there,and what you see is clean. You do not scrub so hard as to bring the paint back up. Maybe the underside stays stained,but not the top. You can't see any stain at all. I can say this has happened in various amounts and colors at least six or seven times and has worked every time.
