Works great cleaning swimming pool filters
Would RecommendTSP is recommended by the manufacture of swimming pool filters that I bought. The TSP breaks down the lotions and oils that accumulate on the filter. Recommended at 1 cup per 5 gallons of water. I soak the filters over night. Rinse them and they look like new.

Didn't seem to do much of anything
Would Not RecommendI bought this to clean the foundation of my house, before painting. There was a lot of plant debris on the foundation from the ivy that had been growing up it. I was not at all impressed with this cleaner, because it's seemed to do nothing to help remove the debris. I had to scrub like crazy and i think the only thing that took it off was the "elbow grease" I had to apply to get the job done. I would have gotten real TSP, but this was the only thing I saw at Lowe's. Don't waste your money. Go so...
Greasy garage floor cleaned

Resealable Bag a Plus
Would RecommendI bought this in a cardboard box last time. Which means if you need to figure out a good way to store it. I used 1/4 sup in 2 gallons of water (wash walls for paint prep) and this is enough to do most the house. I always go back with a second wet rag to "rinse off" any residual left over. Paint jobs always come out great after good prep. But I also prime and do two coats. This is one step to get it right the first time.
