Chemical Guys Maxi Suds II Foaming Car Wash Soap — 1 Gallon Grape Scent, pH-Balanced, High-Foam Lubricity

Maxi Suds II Extreme Grape Rush is a concentrated, super-foaming car wash soap that lifts and rinses away dirt while leaving a fresh grape scent and protecting wax and sealants.

Designed for hobbyists and professional detailers alike, this 1-gallon jug from Chemical Guys delivers thick suds, strong lubricity and pH-balanced cleaning power that won’t strip existing waxes or sealants. The formula uses specialty polymers and water softeners to suspend contaminants in rich foam, reducing abrasive contact with paint and making rinsing easier. Use it with a two-bucket hand wash, a foam cannon, or a foam gun to get slick, scratch-minimizing results on any automotive finish.

How does Maxi Suds II remove dirt without harming wax or sealants?

The formula combines lubricating polymers and foam-active agents that encapsulate grit and debris, lifting them off the surface and carrying them away in the rinse. Because it’s pH-balanced, it cleans effectively without aggressively attacking wax, ceramic coatings, or sealants when used as directed.

• Specialty wash polymers lift and lubricate contaminants.
• Water softeners reduce streaking and water spots.
• pH-balanced formula helps preserve existing protective layers.
• Safe for all paint colors and coatings when diluted correctly.

What dilution and application methods give the best results?

Maxi Suds II is concentrated so small amounts deliver lots of suds. For a two-bucket hand wash, add about 1 oz per 5-gallon bucket; for foam cannon or foam gun use roughly 2 oz per 32 oz of solution, adjusting to reach the foam thickness you prefer.

• Two-bucket wash: 1 oz per 5 gallons; wash top to bottom with a microfiber mitt.
• Foam cannon/gun: 2 oz in 32 oz warm water; increase concentration for denser foam.
• Rinse mitt in a clean-water bucket between passes to avoid recontamination.
• Use a separate bucket for wheels and tires to prevent abrasive transfer.

Will the grape scent or foam damage paint or leave streaks?

The grape fragrance is added for a pleasant washing experience and does not affect cleaning performance. Maxi Suds II’s water softeners and balanced surfactants are formulated to minimize spotting and streaking, even when used outdoors in sunlight, as long as you follow recommended dilution and rinsing steps.

• Fragrance provides a clean smell without compromising cleaning action.
• Formulation helps prevent water spots and streaks when rinsed properly.
• Safe for use in sunlight and on all automotive paint colors.
• Not intended as a decontaminant for heavy industrial fallout—use detailing clay or decontaminants first.

How versatile is Maxi Suds II for different users and vehicles?

Whether you detail a daily driver, a high-end show car, or an RV, Maxi Suds II scales to the job. Its concentrated nature keeps cost-per-wash low while remaining simple to use for beginners and incorporating professional-grade results that pros expect.

• Works on cars, trucks, SUVs, RVs, and most recreational vehicles.
• Compatible with manual wash mitts, foam cannons, and pressure-washer foam guns.
• Concentrated formula reduces packaging waste and storage space per wash.
• Available in several fragrances to suit personal preference.
