Putting solvent on bronze brushes

When using a bronze brush to clean, should you dip the brush into the solvent? If you do, the next time the brush is dipped, the fouling that is on the brush comes off into the jar of solvent, making it dirty. Do you just ignore the dirt in the solvent? Or do you pour the solvent onto the brush so the solvent in the jar stays clean?

Lately, I've been blowing the gunk off with brake cleaner from a spray can after each use of a brush. Works good, and eliminates the valid issue you raise. Also stops solvent action on the brush itself.

I keep an eye-dropper in the cleaning kit. Only the eye-dropper ever goes into the solvent, so the bottle stays clean.

Also, it's easy to get just the right amount into just the right place.

My brushes never go into solvent. I run a clean swatch that I have soaked in solvent through a dirty bore first, let the solvent set in the bore for a period of time,and then run a dry brush through the barrel. I repeat the process until dry swatches come through the bore clean. This keeps the solvent in the bottle clean and the process does clean the bore. The need to soak a brush with solvent escapes me.

I keep a shot glass in my cleaning kit.

I put all my solvents in plastic squeeze bottles, unless they already come that way. You can use the ones that toiletries come in, or the ones that come in printer refill kits (they are the best) or buy special ones from Brownells or others. Don't use food product ones.

That way, you squeeze the solvent on the patch or brush, never contaminating your solvent.

I do what you do. Dunk the bronze bore brush into the jar of Hoppes #9. I know that I shouldn't because the dirt in the previous cleaning will harm the solvent's efficacy. I do use a small bottle of solvent, which is probably only good for about 10-12 cleanings, after which time, its refilled from the large jug of Hoppes #9.

I need to find some of those dispenser bottles, with the spring loaded top that you tap to get the solvent up. So far, I've only found plastic bottles, and I also want a way to stop the top from going down when I'm transporting it.

One thing that I do is wrap my bronze brushes, with a patch, and use this to clean the bore with. The cloth patch holds the solvent and traps the dirt, the brush holds the cloth patch, while the hole thing is pushed down the bore. After, the cloth patch is discarded.

I go to my local hobby shop and buy plastic bulbs, or pipette's that are used to transfer small amounts of paint.

These work very well, and the straw-like pipette portion allows me to put solvent directly into the chamber.

BTW: most bore cleaners now have ingredients to atack copper fouling which also disintegrates a bronze brush. Another good reason to use nylon bore brushes.

MPro7 Solvent comes in spray bottles and does does not eat my brass brushes. I noticed this right away. Surprisingly enough I don't believe they mention this in their literature. But my brushes last practically forever now.

I recently started dipping a clean patch in the solvent, then wrapping it around the brush. You get 2 passes in one, wet patch and a bore brush (bristles will poke through the patch and hold it pretty good). When done, I use brake cleaner to spray off the brush.
