View Full Version : JB Bore Cleaning Compound ... How Do you Apply?

What's the most effective way to apply the JB Bore Cleaning Compound?

I've tried using a barrel mop and running it 20 to 30 times back and forth, and I've tried using a smaller size bronze brush with a patch around it. Both ways are messy, and usually results in me throwing the barrel mop away after using it.

SOmeone give me some ideas before I have to invest in a bulk order of barrel mops. :)

A little bit of JB on a tight patch. Work it part way down, pull back, go a little farther, pull back a little, and so on until you have scrubbed the whole barrel. Once you're done, scrub with solvent and patches until it is clean.

But I've heard of guys making as many as 50 passes before continuing with their regular cleaning solution. What's that about?

I use mops. They're easier to scrub with.

Sometimes people go overboard w/ JB because they expect that it's going to act like a cleaner, and eventually the patch or mop won't discolor when they pass it through the bore. But it always does. There seems to be a chemical reaction that takes place which isn't caused by fouling.

I typically use, and been advised to use, 10 to 15 strokes, and then cleaned out the JB. That works very well.

Like Scorch, I use a jag with a tight patch. I rarely have to use JB since I switched to Wipe-out, a foaming bore cleaner.

A patch on a worn out brush also works well.
