Berryman Carburetor Cleaner Spray — 12-Pack Aerosol, High Energy Solvent for Gum & Varnish Removal

Berryman B-12 Chemtool Carburetor Cleaner is a high-energy solvent spray that quickly dissolves gum, varnish, fuel residue, and carbon buildup to restore carburetor and throttle-body performance.

This aerosol formula uses High Energy Solvent Technology (H.E.S.T.) to break down deposits on carburetors, PCV valves, automatic chokes, linkages, throttle bodies, and distributor shafts. The product is VOC compliant in all 50 states and comes in a convenient 12-pack for professional shops or DIY enthusiasts who service multiple vehicles. Its universal-fit application makes it compatible with most gasoline engine components that suffer from fuel-related residues.

How fast will this cleaner remove gum and varnish?

The B-12 Chemtool is designed for rapid action: its concentrated solvent matrix softens and dissolves hardened deposits on contact, reducing cleaning time compared with plain brake or parts cleaners. Results depend on deposit thickness, but many parts show visible improvement after a few sprays and light agitation.

• High Energy Solvent Technology targets tough fuel residues quickly
• Effective on both fresh and baked-on varnish with repeated application
• Aerosol delivery allows pinpoint spraying into small orifices and linkages

Which engine parts can I safely use it on?

This formula is intended for non-plasticized metal engine components such as carburetor assemblies, throttle bodies, choke mechanisms, distributor shafts, and PCV valves. Avoid prolonged exposure on rubber, painted surfaces, or soft plastics — test a small area first if unsure.

• Safe for metal carburetor bodies, float bowls, and jets when used as directed
• Clears sticky throttle plates and choke linkages for better movement
• Removes carbon and fuel varnish from distributor shafts and small linkages

Will using this cleaner improve drivability and fuel economy?

Cleaning deposits that restrict fuel or air passages can restore smoother idling, crisper throttle response, and more consistent fuel metering — all factors that help drivability. While the cleaner alone doesn’t guarantee specific fuel economy gains, removing buildup that impairs component function often contributes to more efficient engine operation.

• Frees sticky linkages and throttle plates to prevent uneven idling
• Clears jets and passages for more consistent fuel delivery
• Helps maintain peak component performance between rebuilds

Does this product meet environmental regulations?

Berryman B-12 Chemtool is formulated to be VOC compliant across all 50 states, making it suitable for professional garages and home mechanics in regulated regions. Proper ventilation and disposal of emptied cans are still recommended to minimize environmental impact.

• VOC-compliant formulation for nationwide regulatory acceptance
• Aerosol cans should be emptied and recycled according to local rules
• Use in well-ventilated areas and avoid open flames during application

Who is this for? Berryman B-12 Chemtool Carburetor Cleaner, sold as a 12-pack, is aimed at automotive technicians, small repair shops, classic-car restorers, and hands-on DIYers who regularly service multiple vehicles or need a supply of a reliable, fast-acting carburetor cleaner. It's particularly useful when you require a solvent that penetrates and dissolves hardened fuel residues while remaining compliant with VOC regulations.
