Chemical Guys Tough Mudder Off-Road Truck/ATV Heavy Duty Wash Soap - 1 Gallon

Heavy-Duty Foaming Truck Wash Formulated for Off-Road Mud, Grime, and Baked-On Dirt

Chemical Guys CWS202 Tough Mudder is a heavy-duty off-road truck and ATV wash soap engineered to tackle mud, grime, dirt, sand, and road film left behind by trail driving, job sites, and daily off-road use.

The CWS202 formula uses concentrated surfactants to rapidly emulsify and lift heavy contamination from paint, glass, plastic, rubber, metal, and aluminum without requiring aggressive scrubbing. 

At one gallon, the CWS202 provides a high-volume supply for frequent washers, fleet vehicles, or multiple vehicles. 

Dilution at 1-3 oz per 5 gallons of water in a wash bucket or 1-3 oz in a 32 oz foam cannon tank extends the gallon significantly. 

Chemical Guys designed the Tough Mudder formula to rinse off easily, preventing residue buildup and reducing the risk of swirls and scratches associated with grit left on the surface during washing.

Frequently Asked Questions

What is the Chemical Guys CWS202?

The CWS202 is Chemical Guys Tough Mudder Heavy Duty Off-Road Truck Wash Soap in a one-gallon (128 fl oz) bottle. It is formulated to remove mud, grime, sand, and heavy contamination from trucks, SUVs, ATVs, and off-road vehicles. The CWS202 works with foam cannons, foam guns, and bucket washes, and is compatible with paint, glass, plastic, rubber, metal, and aluminum surfaces.

How do I use CWS202 in a foam cannon?

Add 1 to 3 oz of CWS202 to your 32 oz foam cannon solution tank filled with water. Shake gently to mix. Connect to your pressure washer and apply thick foam to the vehicle. Allow foam to dwell briefly to lift contamination, then wash with a mitt and rinse thoroughly.

How do I use CWS202 in a wash bucket?

Add 1 to 3 oz of CWS202 to a 5-gallon wash bucket filled with water. Agitate with your wash mitt to build suds. Wash the vehicle panel by panel using the two-bucket wash method if possible. Rinse thoroughly with clean water and dry with a microfiber towel.

Is the CWS202 safe on waxed or ceramic-coated vehicles?

The CWS202 is formulated as a heavy-duty cleaner designed to cut through heavy contamination. Aggressive detergents may affect the durability of paste wax or carnauba wax coatings over time with repeated use. For vehicles with ceramic coatings, Chemical Guys recommends using their ceramic-specific wash soap to avoid stripping coating boosters. If wax maintenance is a priority, use CWS202 when a decontamination wash is needed and a gentler soap for routine washes.

Is CWS202 different from regular car wash soap?

Yes. The CWS202 Tough Mudder formula uses higher concentrations of surfactants designed specifically for heavy off-road contamination including mud, clay, sand, and grime. Standard car wash soaps are formulated for lightly soiled vehicles. CWS202 is appropriate when the vehicle needs aggressive cleaning after trail use, job site work, or muddy conditions.

What is the pH of the CWS202?

The CWS202 formula has a pH of 8 to 9, placing it in the mild alkaline range. Alkaline formulas are effective at breaking down organic contamination such as mud, road film, and grease. This pH range is generally safe for automotive paint and clear coat, but avoid direct skin or eye contact and rinse thoroughly after use.

Does CWS202 leave any residue?

The CWS202 formula is designed to rinse off cleanly without leaving residue. The formula also leaves a super slick surface after rinsing that reduces fresh mud adhesion. Rinse with clean water after washing and dry with a premium microfiber towel to prevent water spots.

What is the difference between CWS202 (1 gallon) and CWS20216 (16 oz)?

CWS202 and CWS20216 contain the same Tough Mudder Heavy Duty Wash formula. The difference is size. CWS202 is a 1-gallon supply ideal for frequent washing, multiple vehicles, or fleet use. CWS20216 is a 16 oz bottle suited for single-use washing, small detailing kits, or trying the product before committing to a larger quantity.
