Let's see. Spilled coffee. Rust stains that dripped off a plumber's snake. Concord grape juice. A pet's "accident". And that's just off the top of my head as I recall the various carpet stains I've tried to resolve by using, er, RESOLVE SPOT & STAIN CARPET CLEANER.Well, this cleaner is consistent. . .in that it consistently doesn't lift the stains out. The directions are simple enough: Spray the stain, let it soak for at least a minute, wipe up with a damp (and clean) cloth. While I will give this product some credit for lifting a portion of the color out, it still doesn't remove the stain. As they say in the law enforement vernacular, the evidence remains.So if it's complete stain removal you're after, PROFESSIONAL (yeah, okay) RESOLVE SPOT & STAIN CARPET CLEANER is going to come up short. But in all fairness, I've yet to find any carpet cleaner on the market that effectively removes stains. I guess I'm just too messy. Hand me that cranberry juice.--D. Mikels, Esq.
