suds.lab F3 Car Foam Gun, Garden-Hose Compatible — Adjustable Foam & Quick-Disconnect

The suds.lab F3 Car Cleaning Foam Gun converts any standard garden hose into an adjustable foam cannon for a safe, efficient, and fun foamy car wash.

Wash your vehicle with professional-style suds at home without complicated fittings or a pressure washer. The F3 mixes soap and water into a thick, lubricating foam that helps lift dirt and grit away from paintwork while letting you control foam density and soap ratio. It installs easily on a garden hose, features a quick-disconnect, and is built to be paint-safe when used with auto-safe soaps.

How does the F3 create thick foam from a regular hose?

The F3 uses a simple venturi-style mixing chamber and an adjustable nozzle to aerate liquid soap as water flows through. By changing the soap-control grip and foam dial, you tune how much detergent joins the water stream, producing anything from a light rinse to dense foam clinging to panels.

• Garden-hose compatible quick-connect for easy attachment.
• Soap-control grip adjusts detergent draw.
• Foam nozzle and ratio dial vary suds thickness.
• Mixes water and soap into a lubricating lather that clings to surfaces.

Is the F3 safe to use on automotive paint?

The F3 is designed to be gentle: it produces a soft, slippery foam that reduces friction when wiping, lowering risk of swirl marks if you use proper wash tools. For best results, pair with a pH-neutral or car-specific shampoo and avoid abrasive brushes.

• Produces lubricant-rich foam to lift dirt from paint.
• Adjustable soap ratio helps conserve detergent and reduce residue.
• Safe with soft wash mitts and microfiber towels when used correctly.
• Rinse thoroughly after washing to prevent soap spots.

What adjustments let me save water and soap while still cleaning effectively?

The F3’s soap-control grip and foam-ratio dial let you fine-tune detergent use so you only apply what’s needed. Denser foam helps a little product go further by increasing contact time on grime, while lower settings are ideal for light rinses.

• Reduce soap intake with the control grip to conserve detergent.
• Use denser foam to cover surfaces without repeated sprays.
• Lower foam for quick rinses or delicate finishes.
• Quick-disconnect speeds change between foam and rinse modes.

How easy is it to set up and maintain the foam gun?

Setup takes seconds: attach the F3 to any standard garden hose, fill the reservoir with car shampoo, and adjust the nozzle. Maintenance is simple—flush with clean water after each use to avoid buildup, and store indoors away from freezing temperatures.

• Twist-on hose connection needs no special adapters.
• Fill reservoir with diluted car shampoo; tighten cap.
• Flush after use and store dry to extend service life.
• Quick-disconnect for switching to a straight water hose or another tool.
