Bob, Black-Solve concentrate is available from Dixie Gun Works.
Jakob, "Teflon patches" are 100% cotton patch material coated with a thin layer of Teflon. It's an expensive patching option for shooting a patched roundball that is chosen by some competition shooters who want to wring out the last little bit of potential from their rifle/load combination.
For day-to-day offhand shooting, I use a spray on liquid lube. I've observed very little difference on target scores, loading difficulty or anything else with or without wiping. IF you're going to wipe, Smylee Grouch is correct. There are things like jag size and "wiping" patch thickness that have to be optimized for your barrel and load combination to avoid the issues mentioned. Once you get those parameters identified...wiping won't cause any problems.
For myself, the only shooting I do where I consistently wipe between EVERY shot is when I'm shooting off a rest. Chunk, or Bench.
I have a "procedure" I follow in those cases. The results speak for themselves.
