Boat Juice Hydrosuds Foam Sprayer — Garden-Hose Foam Gun, 8 Spray Modes for No-Pressure Cleaning

Boat Juice Hydrosuds Sprayer is a garden-hose-mounted foam gun that creates thick suds for safe, no-pressure cleaning of boats, cars and RVs.

Designed for owners who prefer washing at the dock, driveway, or marina slip, the Hydrosuds Sprayer screws onto any standard garden hose and dispenses heavy foam from an easy-fill cup. It was engineered to reduce scrubbing by letting concentrated soap cling to surfaces and loosen dirt, salt, and grime while remaining gentle on gelcoat, paint, vinyl, canvas and glass. Lightweight and versatile, the unit delivers eight spray patterns and requires no pressure washer or adapters.

How do I set it up and start making foam?

Assembly is simple: fill the clear soap cup with your detergent, attach the sprayer to a standard garden hose, select foam mode, and open the water. The venturi-style nozzle mixes water and soap to produce a clingy blanket of suds that stays on vertical hulls and large surfaces.

• Screw-on connection fits standard garden hoses — no special fittings required.
• Transparent soap cup shows remaining solution for quick refills.
• Switch between foam and regular spray with an intuitive dial.

What surfaces and finishes is the Hydrosuds Sprayer safe for?

The sprayer uses normal hose pressure and is gentle on delicate finishes, so it’s suitable for gelcoat, waxed surfaces, ceramic coatings, paint, glass, vinyl, and canvas when paired with an appropriate marine-safe soap. Avoid abrasive brushes while foam is soaking on sensitive areas to prevent rubbing contaminants into the finish.

• Safe on gelcoat and painted surfaces when using non-abrasive cleaners.
• Effective for vinyl, upholstery and canvas with low-pressure settings.
• Removes marina salt and road grime while minimizing physical scrubbing.

Which spray patterns and cleaning tasks can I expect?

The Hydrosuds Sprayer offers eight distinct spray modes to match different jobs — from a broad flood to coat a hull in foam to a pinpoint jet for stubborn spots. The variety lets you switch quickly between gentle rinses and focused cleaning without changing tools.

• Wide-flood and foam-setting for full-hull or large-panel soaping.
• Soft shower and mist for delicate canvas, seats and electronics-safe rinses.
• Focused cone or jet for trailers, engine compartments, and caked grime.

Do I need a specific soap and how does it perform with Boat Juice Wash & Shine?

While the sprayer works with most concentrated boat soaps, pairing it with Boat Juice Wash & Shine produces denser foam and improved gloss after rinse and dry. Use the recommended dilution to get thick suds that cling and break down contaminants without leaving residue.

• Compatible with common marine-safe, biodegradable detergents.
• Boat Juice Wash & Shine formulated for thicker foam and streak-free finish.
• Concentration control in the cup helps manage suds volume and coverage.

Who this is for: The Hydrosuds Sprayer is made for boat owners, weekend detailers, RV travelers and car enthusiasts who want an easy, low-cost way to apply thick cleaning foam from a standard garden hose. It’s ideal if you wash at home or at the marina and prefer to reduce elbow grease and skip a pressure washer — especially useful for seasonal maintenance, quick post-cruise rinses, and preserving delicate finishes.
