I bought a 4.5 lb box of TSP and a 10 lb bag of STPP.
I tried using about a teaspoon of TSP in the laundry w/ regular detergent seems about right - have suds again and good stain removal.
The STTP arrived the other day, using about a tablespoon w/ detergent in the dishwasher as I write. Will report results.
Hopefully will not get into any trouble with the numerous regulatory and criminal enforcement agencies. (Be right back, somebody is pounding at the front doo
Thanks for the info. Appreciate it.
