Do not buy the Resolve pre-wash stain-treater, especially if you also have the Resolve carpet stain-lifter. Why? Because when you have Fibro-Fog and you’re doing laundry, you may just grab the wrong one. The bottles are identical, except for the label. The carpet stain-lifter is not color fast and I sprayed it on my one of my favorite Broncos shirts. I am now washing a shirt with two towels so that the carpet crap doesn’t ruin any of my other clothes. GRRRRR!!!!! Stupid brain!
