Valvoline Carb, Choke & Throttle Body Cleaner 13 oz — VOC-Compliant, Fast-Acting Deposit Remover

Valvoline Carb, Choke & Throttle Body Cleaner is a high-strength aerosol formula that dissolves carbon, gum, and varnish to quickly free sticky carburetors, chokes, throttle bodies, and intake passages.

This 13 oz spray from Valvoline is built to cut through the deposits that restrict airflow and fuel flow in older and current engines. The fast-acting solvent blend targets unpainted metal surfaces and evaporates cleanly, helping restore smoother idling, more reliable starts, and better throttle response without using chlorinated solvents. It’s VOC-compliant across all 50 states, making it suitable for professional shops and DIY mechanics who need an effective cleaner that meets environmental regulations.

How does this cleaner restore throttle response and idle stability?

The formula quickly softens and removes sticky buildup on throttle plates and bores that cause uneven idle and delayed throttle action. By clearing the deposits that interfere with airflow and sensors, the engine can return to a more consistent operating state.

• Breaks down carbon, gum, and varnish on unpainted metal surfaces
• Evaporates without leaving residue that could attract new deposits
• Safe for use on throttle bodies and intake passages when used as directed

Can I use it on carburetors, chokes, and intake ports safely?

Yes — the product is formulated for carburetors, chokes, throttle bodies, and intake components where deposits accumulate. It removes stubborn residue while being free of chlorinated solvents, reducing the risk of damage when applied correctly.

• Effective on multiple unpainted metal components
• Non-chlorinated solvent formulation for safer contact with parts
• Use in short bursts and follow manufacturer service guidance for best results

Will this cleaner help with hard starting and poor acceleration?

Removing deposits that restrict airflow and disrupt fuel atomization can improve starting behavior and throttle response. While not a replacement for mechanical repairs, cleaning affected components often restores performance lost to buildup.

• Clears contamination that can impede airflow and fuel delivery
• Can reduce hesitation caused by sticky choke or throttle components
• Works as part of routine maintenance to prevent performance degradation

What are the environmental and safety considerations?

Valvoline formulated this cleaner to meet VOC regulations in all 50 states and to avoid chlorinated solvents. Still, use in a well-ventilated area, avoid inhalation and skin contact, and follow label safety instructions for storage and disposal.

• VOC-compliant across the United States
• Formulated without chlorinated solvents
• Follow product label for PPE and ventilation requirements

Who is this for: This cleaner is aimed at professional technicians and home mechanics working on gasoline engines who need a reliable, fast-acting spray to remove carbon, gum, and varnish from carburetors, chokes, throttle bodies, intakes, and other unpainted metal parts. It’s appropriate for routine service, pre-repair cleaning, and preventative maintenance when users follow vehicle manufacturer guidance and safety directions on the label.
