Autogeek Half Gallon Foam Gun

This is the only foam gun to receive Autogeek’s seal of approval!

The Autogeek staff was so impressed with the Foamaster Foam Wash Gun, we worked with the manufacturer to create a special version just for Autogeek. The Autogeek Foamaster is a heavy duty foam gun with brass fittings and a handle and nozzle in our signature colors, red and black. The gun has all the quality and performance you expect from Autogeek plus the assurance of a gentle, sudsy wash.

If you’re a detailer in search of the perfect swirl-free car washing technique (aren’t we all?), then you’ve come to the right place. My staff and I are constantly reading up on the internet and consulting detailers to see what new tools and techniques are out there. Our latest find is the Foamaster Foam Cleaning Gun.

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 paint immediately. As you work your way down and around the vehicle with a mitt or sponge, 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 paint 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 vehicle.

We compared several guns and found that the Foamaster is the best for car washing. 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 Pinnacle Bodywork Shampoo in the Foamaster Foam Wash Gun. This shampoo is super-sudsy when used in a bucket; just imagine how much foam it produces when distributed with a foam gun! As always, use a paint-safe wash tool such as a Pinnacle Chenille Wash Sponge or a Sheepskin Wash Mitt.

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 vehicle from micro-marring and wash-induced scratches with the Foamaster!

If you own a pressure washer, check out the Foam Cannon HP. It generates foam at a higher pressure to maximize cleaning power.

Good but ...

The foam cannon works it shoots out foam!
The canon works and makes foam. It is easy to handle as long as you don't have to lift it over your head.
The foam density is a bit disappointing and the canon difficult for me to hold over my head to foam the roof of my van.

this gun is quality and the features are nice. while i dont personally adjust the ratio its so easy and quick to do which is a nice feature. the quick disconnect is one of the best things about it in my opinion. its got nice pressure with just your garden hose the half gallon is plenty big enough to do any suv, even doing a presoak and then reapplying as you go

Foam gun
March 6, 2016
This foam gun is of solid brass construction and is easy to use. The amount of foam is easily adjustable with the brass meter stem lever. The meter stem lever is also adjustable to turn off foaming action to allow presoaking. There is a quick release handle for final rinse and it produces a strong steam of water. I would recommend the half gallon sized bottle for larger vehicles to be entirely coated in foam.
Ease of use and solid brass construction.

Great gun & lots of foam
December 25, 2015
If you don't have a pressure washer or don't want to use one, this is the one I suggest. Easy to use and makes for a great presoak. I use it on each panel after its soaked while I'm cleaning. Love love it!

Still confused about what goes in the reservoir...concentrated foaming agent or a dilution of foaming agent and water

I finally got the chance to run a test with the new gun and it performed extremely well. With just a small amount of DP X-foam and warm water, I coated my Scion xB with thick foam in no time at all. It "exceeded my expectations" :)
