This product ranks #3 of 5 in Throttle Body Cleaner.
Last reviewed July 5, 2026
TL;DR Clears carbon and oily film from the throttle plate with a low-aromatic formula: Berryman's page states "Safe for use with catalytic converters and oxygen sensors," backed by an SDS showing zero aromatic hydrocarbons. DANGER is health-driven: skin/eye irritation plus a blood-system effect from repeated exposure. Wear gloves and safety goggles; ventilate well.
Pull the intake duct, hold the plate open, spray short bursts across the plate and bore, then wipe with a microfiber. The fast-evaporating light-solvent formula cuts carbon and oily film without an aromatic punch that risks a coated plate or a downstream sensor. No community MAF or O2 code reports turned up for this SKU. Let overspray flash off before reinstalling the duct.
Right buy for a modern-EFI owner doing routine throttle-body maintenance who wants a documented sensor-safe claim. Skip it for GDI intake-valve carbon, upstream of this cleaner's reach, and for carburetor work.
DANGER reflects health-tier hazards, not flammability alone: skin/eye irritation, narcotic effects, and a blood-system caution from repeated exposure. SDS Section 8 calls for chemical-resistant gloves, safety glasses or goggles, and respiratory protection if ventilation is inadequate. CARB compliant, but two solvents are VOC-exempt, so solvent load runs above that figure. Amazon's Prop 65 flag is contradicted by the SDS, which clears the product with no listed ingredients. The solvent blend can dissolve PVC pipe, so don't pour it down a drain.
Yes. Berryman's own product page states explicitly: 'Safe for use with catalytic converters and oxygen sensors.' The SDS chemistry backs this up -- the formula contains zero aromatic hydrocarbons (no toluene, xylene, or aromatic naphtha) across its full disclosed composition, which is the chemistry that actually determines sensor and catalyst compatibility, not just the marketing claim.
The DANGER signal word is driven by health-tier H-codes -- specifically H315 (skin irritation), H319 (eye irritation), H336 (narcotic effects from vapor), and H373 (STOT-RE, affecting the blood system and central nervous system with repeated exposure) -- not by flammability alone. Sensor-safe chemistry (low aromatic content) and low overall health hazard are two different things: this formula is genuinely gentle on catalytic converters and O2 sensors, but the ketone/glycol-ether solvent blend still carries real irritation and narcotic-effect hazards that push the signal word to DANGER.
The Amazon listing carries a Proposition 65 flag, but Berryman's own Safety Data Sheet (Section 15) explicitly states the product is not subject to Proposition 65 labeling requirements, and none of the six disclosed ingredients appear on California's Prop 65 substance list. The SDS is the more specific and authoritative source here -- the Amazon-side flag likely reflects a blanket compliance policy applied across Berryman's broader B-12 Chemtool product family, some of which (like the carburetor cleaner) genuinely do carry Prop 65 warnings.
The throttle body itself is a port-side component this cleaner can reach normally on any engine, including GDI. The caveat for GDI engines is that the real carbon problem tends to build on the intake valves further upstream, which an aerosol throttle-body cleaner sprayed at the plate cannot reach. Cleaning the throttle body with this product addresses throttle-related symptoms; intake-valve carbon on GDI engines needs a dedicated cleaning approach.
No -- these are two distinct Berryman product lines. This product (#2209) is marketed exclusively as an air-intake and throttle-body cleaner with no carburetor or choke language anywhere in its name or listing, and carries an explicit O2-sensor-safe and catalytic-converter-safe claim. Berryman's separate 'B-12 Chemtool Carburetor, Choke and Throttle Body Cleaner' is a combo SKU formulated for the more aggressive carburetor use case and does not carry the same sensor-safe positioning.
