Mopar Throttle Body Cleaner (13 oz aerosol)

Spray into the throttle body bore or carburetor passage in short bursts, let the fast-evaporating formula dissolve carbon and gum for a few seconds, and blow out with compressed air. The acetone-dominant formula leaves passages dry without residue. Amazon reviewers report it removing heavy carbon buildup from Mopar engine throttle bodies in a single application; one reviewer cleaned cylinder chambers successfully as well. Community evidence stays inside Amazon's review corpus for this product — no independent forum before/after threads were found as of this writing, so the score reflects confirmed adequate performance without the community-forum validation the top tier requires. Dual-use positioning (throttle bodies, carburetors, chokes, PCV valves) reflects the label claims directly.

The right buy for a Mopar or Stellantis owner who wants an OEM-issued aerosol cleaner for routine throttle body service or carburetor maintenance and prefers matching brand components. Also reasonable for any mechanic who finds it in stock at a Chrysler dealer parts counter. Skip it if the carburetor has years of lacquered varnish deposits — that level of buildup calls for a dedicated carb-dip solution or ultrasonic cleaning, not aerosol spray. Skip it if you specifically need an O2-sensor-safe or catalytic-converter-safe verified cleaner for a modern fuel-injected system with sensitive sensors — no such claim exists for this product.

The DANGER signal word is driven by the SDS's health H-codes — Eye Irritation Cat 2A (H319) and inhalation narcosis (H336) — alongside the extreme flammability of the aerosol (H222, H229). SDS Section 8 specifies safety glasses or goggles when aerosol mist may reach the eyes and directs use in a well-ventilated area; an organic-vapor cartridge respirator is specified when ventilation controls are inadequate or exposure limits may be exceeded. The label carries the California Proposition 65 warning (confirmed on the rear label image) — SDS Section 15 identifies benzene as a trace impurity in the petrochemical-source acetone and heptane fractions.

The CARB-compliant designation is a regulatory-accounting outcome: acetone, the 90–100% primary solvent, is exempt from California Consumer Products Regulation VOC limits for the carb-cleaner category — but absolute solvent emissions to the atmosphere and lungs remain in the high-VOC bracket (estimated ~750 g/L), because acetone's regulatory exemption does not reduce actual emissions. The SDS confirms acetone meets the OECD definition of readily biodegradable (≥70% BOD), and SDS Section 2 shows no aquatic toxicity H-codes at the mixture level, giving this product a cleaner environmental profile than carb cleaners with petroleum-distillate solvents. Standard disposal guidance applies: do not discharge into sewers or waterways; handle spent solvent as hazardous waste.
