Chemical Guys Tough Mudder Heavy-Duty Foaming Car Wash — 1 Gallon Lemon Scent, pH-Balanced, Safe on Coatings

Chemical Guys Tough Mudder is a heavy-duty foaming car wash soap that creates thick, clingy suds to lift mud and grime safely from trucks, off-road rigs, RVs and daily drivers.

Made for vehicles that see real dirt—trail mud, road film, and construction dust—this 1-gallon formula concentrates powerful cleaning agents into a pH-balanced, lemon-scented wash that won’t strip waxes, sealants or ceramic coatings. Use it through a pressure-washer foam cannon, foam gun, or the classic two-bucket hand wash; the chemistry is tuned to break up stubborn buildup while remaining safe on paint, glass, rubber, plastics and vinyl wraps. The large 128 oz size keeps you stocked for multiple deep-clean sessions or a fleet of vehicles.

How does Tough Mudder remove heavy mud without harming the finish?

This formula produces thick foam that clings to vertical surfaces and encapsulates dirt particles, loosening them from the substrate so they rinse away rather than being scrubbed across paint. It’s pH-balanced and designed to be gentle on protective layers while aggressive on grime.

• Creates dense suds that lift and suspend mud for easier rinsing
• pH-balanced to preserve wax, sealant and coating layers
• Safe on paint, clear coat, glass, wheels, rubber and plastics

Can I use this soap with a foam cannon, foam gun or bucket?

Yes — Tough Mudder works interchangeably with foam cannons attached to pressure washers, handheld foam guns on garden hoses, and traditional bucket-and-mitt washes. Dilution ratios can be adjusted for foam thickness and cleaning power depending on soil level and application method.

• Compatible with pressure washer foam cannons for maximum cling
• Works in suds guns for quick, low-pressure foaming
• Concentrated for economical bucket use on large vehicles

Is the lemon scent and formula safe for specialty surfaces like wraps and trim?

The lemon-scented formula is developed to be both effective and gentle, avoiding harsh solvents that can dull or damage delicate finishes. It cleans adhesives, road grime and bugs while remaining safe for vinyl wraps, plastic trim, rubber seals and gloss/matte coatings when used as directed.

• Non-stripping surfactants preserve protective layers and gloss
• Safe for vinyl, rubber, matte and gloss surfaces with proper rinsing
• Fresh citrus scent improves the washing experience

How much product do I need and what vehicles is it best for?

The one-gallon (128 oz) jug is sized for enthusiasts, shops, and households with multiple vehicles. Dilution depends on how dirty the vehicle is and the delivery method, but a single gallon supplies many washes for cars and multiple washes for larger trucks, ATVs, RVs and off-road rigs.

• Large 128 oz bottle ideal for frequent or heavy-duty use
• Concentrated formula stretches across many cleaning sessions
• Great for trucks, SUVs, Jeeps, ATVs, RVs and work vehicles
