Saturated solution..... mix it into distilled water until no more TSP will dissolve.

All you need is a minute or two in this solution to neutralize the etchant. When the blade(s) come out, they will have a black "sludge" on them, this is the leftover etchant that has been neutralized. I usually go to the swarf bucket under the grinder, and scrub the blade with #0000 steel wool to clean all the sludge off, then clean it good with acetone, oil or wax it and your done.
