J. B. Bore Cleaner (Read 16287 times)

	The barrel cleaner, J.B. Bore Cleaner was developed by Jim Brobst and is currently marketed by Brownells as a mildly abrasive compound consisting of a "carrier" paste and an abrasive, probably some sort of flour of emery, I've used it for years and find it quite useful in several circumstances. Good product ! The product as it comes from the container is a tanish grey color, but after contact with ferrous metal, it turns black in color. Is there some chemical compound in the product that by a chemical reaction causes the color to change. I have used it in a perfectly clean, that is no powder residue and no lead, barrel and the product turns black. Has anyone ever used J B cleaner in their barrel and had it stay the original tanish grey and never turn black, no matter how many passes of the cotton patch were to be made ? Creedmoormatch

	The abrasive is garnet, and even the original turned black. Garnet will break down quickly on steel, but has enough bite to cut lead and get the grease part of the compound under it to help lift it. David

	Chuck Bordman used to use that stuff in his Darr hiwall. The worse it shot the more he used it, the more he used it the worse the gun shot. Thats when he built a Hoch / Smith outfit. He finally wore that one out too so he built another Hoch /Smith outfit. I think it's still shooting okay. Dont know what kind he'll build next. He has some guns he hasnt worn out yet. Joe.

	As I remember from when the other guy came on the scene, he had some formula that the originator had tried and discarded. Facts is facts, the stuff that Brownells is selling is the formula (or at least it was as of three years ago) and the method of manufacture that they got from Jim Brobst. David

	Thinking back to my geology days, diatomaceous earth is a sedimentary deposit comprised of the skeletal remains of diatoms (a type of algae) and is mostly micron-size *silica* with a touch of clay. I've tried it on stocks to knock back the finish, but haven't considered using it in my barrels. And I think garnet has a lower hardness rating on the Mohs hardness scale.

	All very informative responses. I can't answer the question pertaining to whether or not J. B.'s will turn black when used in a stainless steel barrel, I've never owned a stainless barrel, but someone knows the answer. I would like to pose a practicall question; If someone has a leaded barrel and the lead deposit actual exists in the second 1/4 length only. The person doesn't know where in the barrel the lead deposit is, so he/she cleans/scrubbs the entire length of the bore with a rod, jag, cotton patch, and J.B.'s. In this situation, the J.B.'s is scrubbing steel in the first 1/4 length, and the last 1/2 length of the barrel bore. But in the second 1/4 length, the lead deposit is preventing the J.B.'s from contacting the steel until the very last part of the process when the lead is lifted out. Doesn't this situation cause low spots in the first 1/4 length and the last 1/2 length of the bore; and a corresponding high spot in the second 1/4 length ?

I will order a tube,jar of Flitz and make the comparison you speak of for my own information and will let you know if there is a noticeable difference. Actually, Brownells has two separate grades of J B; one is called "J-B Bore Bright" which is part # 083-065-100 and the other is "J-B Non-Embedding Bore Cleaning Compound" and is part # 083-065-025. The best source of information on the two products is David a/k/a 38 Cal or a direct contact w/ Brownells catalog, however, the catalog doesn't give the grit size I don't believe. Creedmoormatch

	After checking many barrels with a borescope I found virtually all cleaners cleaned fouling and leading but never touched the carbon buildup. I always cleaned my barrels thouroughly after shooting fifty shots but found I had a build up of carbon. Use of J B s eliminated this carbon build up in the barrel. Something you never see without a bore scope. Ron Smith always cleans his rifles after each shoot with J B s and has never worn out a barrel after thousands of rounds. He claims it does not wear barrels down. If you are wearing a barrel down you are probably rubbing the barrel with your rod. That is why most of use Dewey rods to prevent damage to our barrels.

	Never found any carbon buildup in any of my rifles Dave. I remember one year at Tommies we could see it in one of your barrels. My load is much milder. Maybe thats why. I use Chucks paper patches, Hoppes to clean my barrels. And a bore guide. Joe.

	Hi Creedmoor: The use of the original JB Bore Cleaner was discussed ad nauseum in the field of Benchrest Shooting. It was found that it would NOT harm a barrel! One can try this product on the outside if a stainless barrel by rubbing a patch loaded with original JB past until one's arm falls off. You will see no damage! If one is getting damage when using this stuff, the damage is coming from another source! BR shooters would never use a harmful abrasive in their very accurate and expensive barrels! I know nothing about the "new" stuff! Good luck, Zeke
