Berryman 0996-ARM B-9 Chem Dip Parts Cleaner with Basket and Armlock, 3/4-Gallon Pail

I purchased the Berryman B-9 Chem-Dip Parts Cleaner with the integrated dipping basket to overhaul a varnished carburetor on my small engine equipment, and it is an absolute miracle worker. The aggressive, professional-grade chemical formula does an exceptional job of melting away baked-on carbon deposits, stubborn fuel varnish, hardened sludge, and thick gum from steel and aluminum components without harming the base metals. Dropping fouled fuel jets, needles, and cast bodies into the chemical bath completely eliminates the need for tedious manual scrubbing or picking at tiny internal passages with wire tools. The structural configuration of the 3/4-gallon metal canister is highly user-friendly and well-engineered. It features a heavy-duty, removable wire basket that sits perfectly inside the bucket, allowing you to submerge dozens of small fasteners and internal linkages deep into the solvent simultaneously without losing them at the bottom. The basket handle extends safely up to the rim so you can lift your components out cleanly without getting the strong chemical stripping agent on your hands or work surfaces. For any mechanic, restorer, or DIYer looking to bring gummed-up fuel system components back to pristine factory performance, this immersion cleaner offers phenomenal time-saving utility and value.

Have not used it a ton but the one carb I dipped so far is currently running the ATV perfectly. Plus it last a while so that makes it even better. The basket inside is also amazing for not having to dig and dig for the parts in the solution.

Does a good job cleaning up the varnish on carburetors.

Can was dented, with the handle bent off, and smashed another unrelated item in the same box. Fortunately didn't leak and probably will still do the job.

Great carburetor cleaner. Like the little bucket that comes in the gallon container for setting small parts in so they get good and clean

I didn't pound the lid shut one time and about a quarter of it evaporated overnight. Works excellent otherwise!

I bought the Berryman Chem Dip Parts Cleaner after years of fighting baked-on grease with sprays, brushes, and pure frustration—and I honestly wish I’d found it sooner. From the first use, it was clear this stuff means business. I dropped in a batch of carburetor parts that were coated in decades of varnish and sludge, and after soaking them in the basket, they came out looking shockingly clean. The built-in basket is a small detail that makes a huge difference, keeping parts organized and easy to lift without fishing around in harsh chemicals. What really sold me is the Armlock pail design. The lid seals tightly, so I don’t have to worry about fumes escaping or the cleaner evaporating between uses. For a 3/4-gallon pail, it lasts longer than I expected since it’s reusable, and a little patience goes a long way. This isn’t a gentle cleaner—it’s a serious, professional-grade solution for anyone who works on engines, tools, or mechanical parts and wants results without endless scrubbing. If you’re tired of “almost clean,” the Berryman Chem Dip delivers the real deal!

Works great for cleaning carburetor

perfect bucket to have around and use of carb cleaning, parts cleaning in your shop. Handier than sprays since you can dunk your parts and leave them in there for a couple hours.

Great product works really well

Perfect as described. I used it for Audi 2.0 oil consumption and for cleaning carbon. Cleaned part of the carbon.

Used the older version of this product some years ago, it was far more powerful, did its job very quickly, this version is takes much longer to work, and even then requires much more scrubbing etc to get the same results. The older version is still available elsewhere.

product worked very well, shipping was quick
