When I was in grad school, I used to use TSPP - tetrasodium pyrophosphate -
for disinfecting tools, as it was readily available through school, as it
was used a lot in clay slips and glazes.

With both chemicals, you need a strong solution and your tools need to soak,
not just be dipped. John is correct though, with the eutrification of
bodies of water due to the high phosphate content, it can be hard to find.
A one ounce per gallon bleach solution is just as good.

One of our societies more prolific growers uses a TSP solution to
sterilize
tools between cuts. I bought some, and intend to use it, but my
husband
cringed and said it would harm the plants.

What say you all?
