Berryman

Berryman Products is a family-owned chemical company based in Arlington, Texas, founded in 1918. The B-12 Chemtool line — carburetor and choke cleaner, fuel injector cleaner, total fuel system cleaner — has been a staple in small-engine repair shops, motorcycle restoration garages, and automotive parts stores for decades. The brand's reputation in the small-engine and powersports communities is strong; Berryman B-12 is one of the most recommended carburetor cleaners on lawn-mower and vintage motorcycle forums, particularly for sit-started seasonal equipment with mild-to-moderate fuel varnish. The product line spans VOC-compliant and standard formulations depending on the state of sale.
