McKee's 37 Marine & RV Quart Foamaster Foam Gun

Fans of McKee's 37 Marine & RV Car Care Products will love the McKee's 37 Marine & RV Quart Foamaster Foam Gun. With brass fittings and a red and black nozzle, the McKee's 37 Marine & RV Quart Foamaster delivers a thick layer of foam to your boat, RV, or vehicle to give the surface maximum lubrication as you wash. The reservoir features the trademark McKee's 37 logo to match your collection of McKee's 37 products!

The idea behind a foam gun is to minimize the amount of rubbing and scrubbing necessary to clean the vehicle by pre-soaking it with frothy foam.The foam starts loosening and lubricating the surface immediately. As you work your way down and around the vehicle with a mitt, sponge, or brush you don't have to use as much force to remove dirt and debris. It's already loose and just needs slight agitation to release it from the surface.

This gentle touch substantially decreases the risk of micro-marring because the paint is covered in a foamy layer of lubrication. Used in combination with a premium car shampoo, the Foamaster is a guaranteed safe way to wash your boat, RV, or vehicle.

We tested several foam guns and found that the Foamaster is the best for washing boats, RVs, and cars. It creates a substantial amount of foam by forcing water through the nozzle where it mixes with the diluted car shampoo that is in the gun's reservoir. The foam is richer, thicker, and sticks to the vehicle longer than soap applied by hand because the dilution ratio of the soap is higher.

Many detailers we talked to use the Foamaster as they wash with a mitt or sponge, instead of as a pre-soak, or sometimes in addition to a pre-soak. This technique involves spraying the foam directly in your mitt's path. The foam is its frothiest upon contact so this method ensures a thick, sudsy layer of foam between the mitt and the paint surface. If you use this technique, just take care to avoid hitting the nozzle on the paint as you disperse the foam. Since you’re using both hands, this takes a little coordination. Practice makes perfect!


The Foamaster’s nozzle is constructed of brass, giving it excellent, long-lasting performance and durability. The handle, foaming tip, and reservoir lid are all made of heavy duty plastic, and the reservoir itself is chemical resistant polyethylene. This industrial grade foam gun is used by more detailers and enthusiasts because it’s built to last. 

The Foamaster is available in two sizes:

75QCFMR – Quart Foam Gun w/ multi-ratio stem and deflector.
75HGFMR – Half Gallon Foam Gun w/ multi-ratio stem and deflector.

Multi-ratio Stem - The multi-ratio stem gives you five settings so you can adjust the dilution ratio of your shampoo. The chart below shows you the shampoo (oz.) to water (gal.) ratio based on the position of the stem.

Deflector - This piece can be used instead of the foam nozzle to deflect exiting water downward and into a wider path. This piece is best suited for spraying non-foaming cleaners over a broad area.

  • Accurately mixes and sprays foaming chemicals
  • Foam generating wand creates a thick, clinging foam
  • Detach handle for a powerful spray rinse
  • For cleaning, degreasing or disinfecting when a foam is desired to increase surface contact time
  • Easy to fill wide mouth, chemical resistant polyethylene quart or half gallon bottle
  • Built-in screen filters out sediment before it reaches your vehicle

*If you are going to use the Foamaster on your vehicle, use it exclusively for your vehicle to avoid cross contamination.

Operational Specifications
  • Water Pressure - 40 to 90 psi (for maximum accuracy 40 to 60 psi)
  • Output - 1-1/2 gallons per minute
  • Spray Pattern - Foaming attachment provides a fan spray, removes for a solid stream. Deflectors are available for fan spray patterns for non-foaming chemicals.
  • Anti-siphon - Protects water supply by preventing soapy water from siphoning back into the hose. (Note: a slight discharge of water from base of handle when water is turned off is normal and indicates anti-siphon is functioning properly.)
  • Customized Ratios - Can be set from 1oz. per gallon to 12 oz. per gallon. (Note: this range is affected by the viscosity of the chemical.)

I recommend using a wash formula designed specifically for use in foam guns. Use McKee's 37 Marine & RV Carnauba Wash & Wax for your boat or RV and McKee's 37 Marine & RV Xtreme Foam Formula Auto Shampoo for your car. These shampoos are literally made for the foam gun with hyper-foaming cleansing agents and rich lubricants. As always, use a paint-safe wash tool such as a Micro-Chenille Wash Mitt or an appropriate brush

After each use, rinse the nozzle and foaming mechanism with clean water to remove any soap residue. This will prevent soapy build-up inside the nozzle and on the brass mechanisms. With regular cleaning, the Foamaster will give you years of trouble-free performance.

The Foamaster Foam Wash Gun has the features you want and the durable construction you need. Protect your boat, RV, and car from micro-marring and wash-induced scratches with the Foamaster!
