Oxy Portable Solution 32 oz.

The 32-ounce bottle is a solid value—I've already used it on two different carpet spots and it lifted both without much scrubbing. The fast-acting formula definitely lives up to the claim for set-in stains.

I sprayed this directly on a greasy pizza stain that had been ground into the carpet for weeks, and it lifted out completely after just a few minutes of soaking. The fast-acting formula really does break down set-in grime without requiring a ton of scrubbing.

Used this on a 3-year-old coffee stain I thought was permanent, and it lifted right out. The formula is runny enough to soak into carpet fibers without leaving residue.
