I recently purchased a foam cannon for my 1800psi karcher power washer and tried it out today. It seems no matter how I played with the settings on the gun I couldn't get thick foam that clings to the car. I filled the bottle about half way with water and added two ounces of Meguairs deep crystal wash. I'm not sure if I need more soap or maybe if I need to use a different soap. Any help would be appreciated.
I think you need something like a "snow foam" product. Those that I read about having foam cannon's don't really use deep crystal wash to my knowledge.
Thanks, i didn't know the soap made a huge difference. I think I'll have to get some Duragloss soap and give it a try.
Megs deep crystal wash is junk. If you are planning to use Megs product, try out Hyper Wash or Shampoo Plus. Both work pretty well with a foam cannon, Shampoo Plus surprised me. Both are cost efficient too.
that's a strong solution you are using, and isn't cost effective either. I use 2 oz of Megs Hyper wash, and the rest of the bottle filled with water. Works very well with Cam Spray PW and foam cannon. DP is an excellent choice. Too bad they don't have it on sale very often, because @ $50 a gallon it's pricey. Megs Hyper Wash is much cheaper, and works equally well...
Chemical Guys Maxisuds II its cheap and works great 2oz to 900ml of filtered water shake it up a bit because its some thick gel like soap and set the dial to the max foam setting and you will blanket your vehicle in thick saving like foam. I also have a Karcher mine is the 5.85 M which is 1.5 gpm and 1850psi the foam cannon I got from PWM it works great. The gallon should last you a year to over a year if you are washing one vehicle weekly. Car Wash Shampoo Maxi Suds No Wax
I've forgotten how long its been since I started using a foam cannon.......While foaming is exciting to the eyes its not everything. DP will foam like crazy, but cleaning is lame as are many foam touted soaps. The reason for foaming is to increase dwell time, and try to limit mechnical washing. I can get a darn good touchless wash with chemical guys citrus wash and gloss, excellent foaming, great dwell time, the best cleaning of all I have tried (I've tried a TON). I mix 2oz to 28oz of water, you can add 1oz of Z7 seems to help with foaming. Turn down the RPMs (throttle down) on the washer and lay out the foam. One of largest contributors to good foam is water quality, if I use DI water I can use WAY less soap and get the same effect. Cheers, GREG
