McKee's 37 Xtreme Foam Formula 128 oz.

Formulated for foam guns and foam cannons.

Does more foam create a cleaner vehicle? It does if it comes from McKee's 37 Xtreme Foam Formula Auto Shampoo.

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.

When blasted through a foam gun, McKee's 37 Xtreme Foam Formula is at its best because it’s the only car shampoo formulated for foam guns. The high soap to water ratio produced by a foam gun allows this intense shampoo to produce FROTHY FOAM unlike any shampoo you’ve used before. The high viscosity of McKee's 37 Xtreme Foam Formula allows the suds to cling to the vehicle in order to begin grabbing dirt and oil on contact. With the help of a soft, clean sponge or mitt, you’ll achieve an Xtreme clean with this super-sudsing car wash.

A lot of soaps can clean, but they can’t leave the kind of shiny, smooth finish created by McKee's 37 Xtreme Foam Formula. McKee's 37 proprietary cleaning agent builds thick, multi-tiered bubbles that work to lift dirt and grime off the surface of the vehicle. Though it contains effective cleaning agents, McKee's 37 Xtreme Foam Formula is pH-balanced to retain the existing paint protection. McKee's 37 Xtreme Foam Formula leaves waxes and sealants intact while removing the dirt and debris that hide your vehicle’s shine.

McKee's 37 Xtreme Foam Formula is the only car wash made for foam guns,

McKee's 37 Xtreme Foam Formula maximizes the performance of foam guns and foam cannons.

Water softeners in McKee's 37 Xtreme Foam Formula help offset the effects of hard water so your vehicle dries with fewer water spots. These softening agents also allow the shampoo to achieve its full foaming potential.

Since most swirls are introduced during the wash process, our rich, foam formula contains an xtreme amount of lubricants and beneficial oils. These lubricants wrap around dirt and suspend it just above the paint surface, where it cannot scratch the paint. The oils nourish the paint to deepen the color and enhance the shine.

McKee's 37 Xtreme Foam Formula has a clean, fresh mint fragrance plus a bright green color to compliment its fluffy, white suds. CLEAN looks and smells like this.

Enjoy the rich, fragrant lather of McKee's 37 Xtreme Foam Formula in your foam gun or wash bucket.

Add 2-3 ounces of shampoo to the foam gun
Add 2 oz. of McKee's 37 Xtreme Foam Formula to the foam gun canister
Screw on lid and start foaming your car!
Shake to mix shampoo and water



Foam Gun

  1. Pour two ounces of Xtreme into the foam gun’s reservoir after filling it with 6-8 ounces of water. Shake well for maximum foam. Set the multi-ratio stem to the maximum foam output, which is the last notch.
    Note: the Autogeek, Pinnacle and Wolfgang Foam Guns all feature a quick connect between the hose nozzle and foam gun’s lid. Filling and shaking the foam gun is easier if you release this quick connect.
  2. Turn the water on and coat the vehicle in foam, one section at a time. You can pre-soak the vehicle and then follow up with your wash mitt or follow along with your mitt as you spray the vehicle. Either method is effective.
  3. Wash from the top of the vehicle down and rinse your mitt often to prevent swirls. Rinse the vehicle often.
  4. Once the vehicle is washed and rinsed, dry it with a Cobra Guzzler Microfiber Waffle Weave Drying Towel to prevent water spots.
Wash Bucket
  1. Pour 2-3 ounces of Xtreme into a 5 gallon wash bucket, such as the Pinnacle Complete Wash System. Activate foam with a strong jet of water.
  2. Wash the vehicle as directed above. Rinse and towel dry.

Does what it was made to do.
Exactly do what it's intended for, with a lot of foaming action to clean without stripping the wax.

Sheen AND Clean
I am a disabled American Veteran with severe mobility issues and this foam formula works so well without excessive physical stress in the application and rinsing process. It makes my van look like new each and every week. Thank you to Mckee's and Autogeek for making it available.

Works exactly as described in a foam cannon.
I was a little skeptical as to whether or not this product could be as good as the other reviews that I read before purchasing. It really is as good as everyone describes!

Best wash hands down
I'm using this wash with the autogeek foam cannon. It produces tons of foam that really helps lift dirt and hard grime of your paint. After washing paint has extremely smooth feeling. Great service and fast shipping as expected from Autogeek.
ProsDirt lifting effect Hard stain removal Smells nice (not that it matters) Tons of foam when used with foam cannon Great wash

DP Xtreme Foam
What can I say, it does what it says it will do. Foams up better than the other shampoos I've used. I use it to pre-soak my vehicle before the actual wash.
ProsExtreme foam action, high lubricity, great shine.

Great foam gun soap
Perfect for foam cannon or gun. Subtle mint smell. Foam really protects finish while letting contaminants safely slide off. The pump option I nice, but th threads don't match the gallon correctly.
ProsVery small amount needed for a wash. Only need one bucket wash when using gun.
ConsPump doesn't screw on correctly.

Excellent product
Great product! - Bad matchup with dispenser pump sold extra!
ProsExcellent foaming capability when used with a foam gun, coats the car in foam!
ConsI bought the dispenser pump for the 128oz jug, however the threads on the jug and pump don't match up. I had to wrap electrical tape around the pump cap and the 128oz container to make it work without spilling product everywhere. If you do this you'll have to be careful not to tip the jug over on its side or you'll pour the product on the ground. Not an ideal situation.

Awesome product.
All I can say is WOW!! Like other comments, the smell is a type of Wintergreen and is awesome. I can't compare it to other products as this is the only one that I have used with a foam cannon. I have used this on both a 1600 PSI and 1700 PSI electric pressure washer. It leaves suds just the way I prefer, not thick like shaving cream nor watery like soap water. I have attached a pic for your viewing pleasure. Not only does it lift the dirt, but also leaves a hydrophic type of barrier on the paint, like rain x. If you do not use wax or a paint sealant, it is very noticeable. Highly recommend. Hope this helps.

Have used this product w/ the foam nozzle on a regular hose for several years. Always provides great suds. Have not found another product that provides the consistent foam/suds as this product does. Would highly recommend to those looking for a simple, quick, easy way to wash your vehicle in your driveway.
ProsConsistent foam, slick surface, easy to use.

ProsIt works. I use it on a regular hose. I have torn both rotator cuffs in each shoulder, this makes keeping the finish on the RV easily.

Let it foam, let it foam, let it foam
WOW! If you are using a Foam Gun or Foam Cannon, you MUST try this shampoo. Smells great, cleans great and foams like nothing else I have tried. Very effective at lifting dirt and suspending it for removal. You will not be disappointed.
