32 oz. McKee's 37 Power Wash

McKee's 37 Power Wash is a high-foaming, wax-infused shampoo that gently removes dirt and road grime while adding real carnauba wax protection to your vehicle. McKee's 37 Power Wash is the only high-yield foaming auto shampoo that contains carnauba wax, increasing protection and shine after every wash. The thick, rich foam created by McKee's 37 Power Wash encapsulates dirt particles, eliminating the chance of wash-induced swirl marks and scratches. McKee's 37 Power Wash is the auto shampoo that does it all!

32 oz. McKee's 37 Xtreme Foam Formula

This high yield foaming auto shampoo bursts into mounds of suds when introduced to water and agitated. The bubbles work to encapsulate oily residue and dirt even before your mitt touches the paint. This rich foam - combined with our own advanced cleaning agent- leaves your vehicle looking and feeling fantastically clean and bright.

16 oz. McKee's 37 Sio2 Auto Wash

McKee's 37 Sio2 Auto Wash was formulated for the unique cleaning requirements of vehicles that are coated with a paint, wheel, or glass coating. This thick, luxurious shampoo creates mountains of foamy suds that encapsulate dirt and grit particles, leaving behind an extremely glossy finish! You can confidently use McKee's 37 Sio2 Auto Wash in direct sun because this pH-balanced, non-alkaline shampoo contains water-softeners that reduce spotting. Works equally well on non-coated vehicles as a gloss-enhancing auto wash. Your vehicle has never looked this good after a simple wash!

22 oz. McKee's 37 Hydro Blue SiO2 Coating

What if we told you that coating your vehicle with protection that lasts 3 months or longer was as simple as spraying on and rinsing off with a hose? McKee's 37 Hydro Blue does exactly that. This highly-advanced Sio2 coating is applied exactly as described above; waxing your car has never been this easy. McKee's 37 Hydro Blue can be used as a stand-alone form of paint protection, or as a booster for your favorite paint, glass, or wheel coating. That's right: McKee's 37 Hydro Blue is 100% safe for ALL exterior surfaces.

McKee's 37 Quart Foamaster Foam Gun

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

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 McKee's 37 Xtreme Foam Formula in the Foamaster Foam Wash Gun. This shampoo is 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.

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!

    Exactly what I was looking for

    I didn’t want to have to pull out my pressure washer every time I wanted to wash one of our cars. This foam gun along with the Extreme Foam Wash puts out an amazing amount of foam. Even on a sunny day, I can foam the entire car with gun, wash it with a mitt and keep it wet and foamy until it’s rinse time. It not only makes the process quicker, it makes the vehicle really shine. I’m very happy with it!

    Just want to have a clean car?

    I am not a fanatic clean car guy. Just wash it now and then, but don’t like the cost or the paint swirls of going to the car wash. Plus it’s 15 min there and 15 back plus time in line… wastes 45 min at least. Bought this kit and added one of their blue drying towels. Rinse the car, foam it with the foam gun (it foams up like crazy! I have a mitt but I’m lazy… I have a super soft long handled car wash brush, I gentled wash the car going in straight passes, one half and then the other. Rinse it, dry it in under 5 minutes. (Watch their video, I use medium sized towel) Leaf blower around the trim, towel off the drips… clean car in less than 15 minutes. I do have the sprays for rims, the post wash spray on/rinse off treatment but most of the time I just want to wash and dry and be done ASAP. All this stuff is fine for people where a pristine car is important but there must be a huge market for people who just want to clean off the everyday dirt, dust and grime. Car washes DO mess up the paint… this kit puts tons of foam on the car, the towels work 5X better than I thought was possible. You can wash your car fast and with very little effort, Foam gun has fast disconnect and quart size will do a whole car. Be lazy, this kit works!

    McKee's foamaster Gun Kit

    I'm happy I bought this Foam Gun Kit. The foam gun worked as I expected. Lots of suds with McKees Extreme Foam shampoo and I used minimal soap with the gun on level 3. More suds if on level 5. This is not intended to produce foam canon thick suds. If you want that, then buy a foam canon & pressure washer. This works great for me. Makes washing the car easier & faster. The soapy suds was plenty. I used the Hydro Blue on my wheels. The water beaded up and with one drive around the block they were shinny & dry. Very happy with this purchase. You can always count on McKees for quality products. Quart Foamaster Foam Gun Kit Quart Foamaster Foam Gun Kit Review
