Chemical Guys Watermelon Snow Foam Car Wash Shampoo — 64 oz, Scented Foam Cannon Formula, High-Foaming Slip

Chemical Guys Watermelon Snow Foam is a scented, high-foaming car wash shampoo formulated for use in foam cannons, foam guns, or two-bucket hand washes to lift dirt while lubricating paint.

This limited-edition watermelon-scented Snow Foam concentrates into thick, clingy suds that encapsulate and remove surface grime without harsh abrasion. Designed for both professionals and enthusiasts, the formula mixes easily for bucket washes, foam guns tied to a hose, or pressure-washer foam cannons. It rinses clean, works on every vehicle color and finish, and offers a more slippery wash to minimize marring when used with a quality microfiber wash mitt.

How do I use Watermelon Snow Foam for the gentlest wash?

Start with a two-bucket system: one soapy bucket and one rinse bucket to avoid reintroducing grit to the paint. Use a premium chenille microfiber mitt, wash top-to-bottom, and rinse the mitt in the clean bucket before returning to the soap bucket to prevent swirl marks.

• Add 1 oz per 5-gallon bucket for a standard bucket wash.
• Use a separate bucket or brush for wheels and tires to avoid contamination.
• Rinse thoroughly and dry with a clean microfiber towel to prevent water spots.

What’s the best way to dial foam density with a foam cannon or gun?

Fill the foam solution bottle with warm water and add 2 oz of Watermelon Snow Foam for a typical cannon fill. Adjust the air-to-solution ratio on your cannon or gun to increase or decrease foam thickness; add more shampoo for thicker, longer-lasting foam layers.

• Start at 2 oz per bottle and increase by 0.5–1 oz if foam is thin.
• Tweak the cannon’s air inlet and nozzle until foam clings to panels.
• Allow foam to dwell briefly, then rinse top-to-bottom.

Will this soap work on my paint, trim, and wheels?

Yes — the formula is safe for all automotive paint colors and finishes when used as directed. For wheels and tires, clean them separately and consider a wheel-specific cleaner for heavy brake dust before using the shampoo for the bodywork.

• Safe across common manufacturers and vehicle types including cars, trucks, SUVs, RVs.
• Use separate tools and buckets for wheels to avoid cross-contamination.
• Follow product dilution instructions to avoid over-concentration on delicate surfaces.

How does this product help prevent scratches while washing?

Watermelon Snow Foam creates thick suds that lift and suspend dirt particles, reducing the need to rub grit across paint. Combined with a two-bucket method and a soft microfiber mitt, the shampoo adds slip that helps the mitt glide over surfaces rather than dragging debris along them.

• High-foaming surfactants break bond between dirt and paint.
• Lubrication in the shampoo lowers abrasion risk during contact cleaning.
• Using separate rinse and wash buckets further reduces contamination.

Who is this for: Chemical Guys Watermelon Snow Foam is aimed at detailers and car owners who want a high-foaming, pleasant-smelling shampoo compatible with foam cannons and hand-wash methods. It suits weekend enthusiasts, mobile detailers, and professional shops looking for safe, slip-rich washing that helps preserve paint clarity when paired with proper washing technique.
