Just reiterating I love the F.A.R.T.
I have a FART tumbler inbound. Really looking forward to addressing my brass backlog, and reducing my lead exposure.
I’m considering adding EDTA to chelate the lead. Looks like the solution needs to be at pH 8 to dissolve the EDTA powder but that’s easily done with some washing soda.

From the papers I’ve read on washing lead contaminated soil, you only need a ~2 millimolar solution of EDTA. Roughly, that works out to 1 gram of EDTA per liter of water. Apparently you need to titrate the water to pH 8 in order for the EDTA to dissolve. I think we can just discard the solution since the lead is bound.
