- Shooter's Choice Xtreme Clean. This is a bore solvent dispensed from a spray can that is particularly useful for cleaning shotgun barrels. Want to see it work? Spray it into the bore of what you think is your clean shotgun barrel, let the barrel sit overnight, and see what comes out in the morning.
- Browning Midas Gun Oil and Grease. They come in syringe-type plastic dispensers, which enable you to put a very small amount exactly where you want it. I particularly like the grease, which is clear and does not attract dirt. I used it on my trap gun, which gets hot enough to fry up a mess of okra (although why anyone would want to eat the stuff is beyond me), and it did not melt or run.
- Bore Tech Inc. Copper Remover and Bore Solvent. Both products are highly effecttive. The Copper Remover is more of a gel than a liquid, which means it won't run all over the place, and the Bore Solvent smells far less ghastly than other solvents of equal effectiveness. You should be able to get all of these items at any gun store.
