Description
Run your gun hard and hot, and regular bore solvent starts to feel like it's working overtime. That's the whole reason Hoppe's put out the Black line. This 4 oz aerosol cleaner is formulated to cut through the heavy carbon that modern sporting rifles and gas-operated guns pile up after a long day at the range, and it does it with the touch of a button instead of soaking and scrubbing over and over.
What the Hoppe's Black Aerosol Actually Does
The formula is engineered to break down carbon, powder residue, lead, and general grime without babying your metal or polymer parts. It works on any firearm bore, so while it was designed with AR platforms, competition pistols, and long-range precision rifles in mind, it's just as happy cleaning your hunting rifle or shotgun. Hoppe's rates the Black formula to hold up across a wide temperature range, from around 65 below zero all the way up to 540 degrees, so it stays put whether you're cleaning in a cold garage or wiping down a barrel that's still warm.
Why the Extension Tube Earns Its Keep
The little straw is easy to overlook, but it changes how you clean. Snap it onto the nozzle and you can drive the spray straight into the chamber, up into the action, or down into the tight spots around the bolt carrier where carbon loves to bake on. No overspray, no wasted product, and a lot less taking things apart just to reach a corner. Pull it off and you've got a wider fan for general wipe-downs.
Getting the Most Out of Your Hoppe's Black Cleaner
This is the first step in a good cleaning routine, not the whole thing. Spray it on, let it sit and loosen the fouling, then work it with a bore brush or nylon brushes and patch it out until the patches come clean. Follow up with a quality oil or CLP to protect the metal and lube the moving parts, since the cleaner is built to strip grime rather than leave a lasting protective film. Made in the USA and part of a full Black system that includes precision oil, copper cleaner, and grease if you want to round out the kit.

Frequently Asked Questions
What makes Hoppe's Black different from regular Hoppe's No. 9?
The Black line was built specifically for the way people run modern guns today, firing a lot of rounds fast and hot. It's engineered to attack the heavy carbon buildup you get in AR-15s and other gas-operated, high-round-count firearms. Regular No. 9 is a great all-around bore solvent, but Black leans harder into cutting baked-on carbon quickly.
Can I use this Hoppe's Black cleaner on any gun, or just ARs?
It's safe to use on any firearm bore, so it works on rifles, pistols, and shotguns alike. It was designed with modern sporting rifles and competition guns in mind, but there's nothing stopping you from using it on your bolt gun or hunting rifle. It handles carbon, lead, and powder fouling across the board.
What is the extension tube on the aerosol can for?
The included straw snaps onto the nozzle so you can direct the spray precisely into the chamber, action, and tight spots around the bolt carrier. It cuts down on overspray and lets you reach areas you'd otherwise have to disassemble to get to. Pop it off and you get a wider spray pattern for general cleaning.
Do I still need to use oil after cleaning with Hoppe's Black?
Yes. This cleaner is designed to dissolve and strip carbon and grime rather than leave behind a protective coating. After you spray, let it work, and patch the bore clean, follow up with a good oil or CLP to lube the moving parts and guard against rust. Hoppe's makes a Black Precision Oil that pairs with it if you want to stay in the same system.
