Hornady One Shot Gun Cleaner and Case Lube, 10 oz – Aerosol Dry Lube, with DynaGlide Plus – Clean, Non-Sticky and Easy to Use – Contains No Petroleum, Won't Contaminate Powder or Primers

Cleans carbon fouling reasonably well with a short burst or two, thus conserving the spray. That's good, because it is quite expensive. I now bring a can with me anytime I go to the range. There, I might need something that can clean a bit as well as refresh the lubricant. It is useful on the reloading bench as well. Definitely still a five-star product after 7 months of frequent use.But it is mainly an excellent lubricant that can be a cleaner in a pinch. Why? Cost. And effectiveness.I can't see using this as a general cleaner very often, such as for the bore. W-a-a-a-y too expensive. Plus there are a number of solvents which will remove powder (carbon) and copper fouling much more easily and which are much less expensive. No, save this for cleaning and re-lubing the mechanism such as the trigger group, bolt group, hammer, striker, or whatever comprises the moving internals of your firearm. Apply it, let it dry, and see the effects of this excellent lube. It will save you the job of dissembly or the cost of having a gunsmith dissemble (or re-assemble!!) your gun.Even here, it might be cheaper to first thoroughly clean the mechanism with an aerosol no-residue gun solvent (or -same thing, really- non-chlorinated brake cleaner). Let it drain and dry, then apply One Shot in several bursts.The film of lubricant which it leaves is thin, dry, and VERY slick. Could be very good for lubing magazines and springs after cleaning with a solvent, since One Shot won't contaminate the primers once it dries.So I think it is good to spray on the internal mechanism of a gun, which is where it shines as a cleaner by removing any final traces of old gummed oil and grease, leaving a dry, rust-resistant film in their place. This film will not hold grit or dust. But I like to lube a very few places like slide rails on an autoloader, which see much heavier use, with some additional quality gun grease or oil. (I am sure One Shot would be adequate by itself for a short period of time.). The lack of any residual mess makes it handy for ccw guns. Plus a dry film will not grab onto lint from clothing, a problem with hanguns carried insude the waistband or in a pocket holster.I don't think the manufacturer would be using "cleaning" as a selling point when this is so obviously a unique and excellent lube, if there weren't so many shooters who want a CLP product. In the field or a camp, you can use virtually any gun oil as a cleaner if you have a rod or pull-thru, brush, and some patches. Will it do a great job? No. But it can get you shooting . I think most CLP products are like that. It is nice that One Shot can clean, but outside of cleaning the internal mechanism of a firearm, it is a best used as great lube, not as a great cleaner.Other uses include lubing the pivot points of folding knives and the moving parts of instruments such as calipers. Should find applications on autos or motorcycles as well.

I use Hornady One Shot primarily to protect and lubricate outdoor gear. That is not the limitation of its uses, however, I have used it to lubricate squeaky hinges and machinery parts, and it works very well for that. It is not a penetrating oil for freeing rusty nuts/bolts, but that is not what it was designed to do. Amazon sells other products for that - my favorite is Kroil.I learned about One Shot watching a video on my favorite internet video format in which the content creator did some unscientific, but real world testing on several lubrication/protection products and One Shot scored very high in his backyard tests; and if I remember correctly, scored at the top for rust protection.One Shot is a dry lubricant that goes on wet. It is obviously in an aerosol can, but dries fairly quickly, which is an advantage when lubricating and protecting outdoor gear. Because it dries, it doesn't tend to attract and hold as much dust as products that don't' dry. Dry lubricants of this type are not intended for high friction or rapidly moving, continuous cycling applications. Using them in those conditions can have detrimental effects. They are not your multi-purpose lubricants that can be used in every application, but when used for what they were intended, One Shot excels far above multi-purpose lubricants.I have and will continue to use One Shot for the applications I need it. When I first bought the product, it seemed more reasonably priced. Whether demand, or popularity, or notoriety has increased its price, I don't know, but now it is reserved for specific applications in my world and I'll use a more reasonably priced product to quite that squeaky door hinge.

I use this product for many things and it works wonder. The price has gone up a lot but there is no substitute for me.

I use this product when re assembling and cleaning my firearms. It’s not oily or greasy and cleans at the same time. It is a little on the expensive side but a little bit goes a long way so it lasts a long time.

This stuff works great as both a cleaner and a lubricant. I have used it on pretty much every category of firearm from semi-auto handguns to pump shotguns. As a cleaner it seems to break down carbon and other gunk for easy removal and leaves a waxy film of lubricant behind. I usually follow up with very small quantities of other lube on the high friction areas (slide rails) but rely on this for everything else. Seems effective as a corrosion preventative, however I rarely store my firearms in saltwater, so your results may vary. Some guns seem to like a "wet" lube better.I knock it down a star because it's expensive and really doesn't last that long. At least 2x CLP. In order to stretch my usage out I usually clean the gun with something else first to get the obvious stuff off then follow up with a blast of One Shot which I wipe out to get any remaining carbon or powder residue, then one more shot of One Shot that I let dry (which only takes about a minute.Pro: Easy to use, works greatCon: Expensive

Primarily used for cleaning dies, does an excellent job removing build up of lube and other build up.

This is what we always use to clean and look be our handguns.
