Use it between targets in score match
I use it between targets in an IBS score match. I scrub with Accelerator for two patches, then a patch of Patch-out, leaving it to soak for as long as I have time for. Usually about 10 minutes. Then a couple of dry patches and a patch of Lock-Ease. I'm right back on my mark first shot. I repeat this after the match but leave the Patch-out in. When I get home I use Accelerator and Wipe-Out foam. Usually two applications get out anything that's left, which is very little. Accelerator and foam are all that is needed for serious cleaning down to bare metal of even the most fouled bore, even the rough ones. The bad bores can take a while though.
