How To Select a Fitting for the Foam Cannon HP
If your pressure washer does not use one of these, it is most likely the one that looks like a 3/8" air hose line disconnect.
These are the fittings that AG carries :
I have an old Kracher K-Series, and Dad's is the kracher HD/HDs type.
If you have the HD pressure washer, the fitting in the post above is most likely what you need. They have it next to the different spray nozzles ( 5*-15* 30* 40* kit ) and siding washer adapter.
If it is the thread type as shown in the URL above, that is the disconnect. I don't think you can add a quick disconnect to these, but you can experiment with the HD set if you wanted to try to add it. Don't know how well that would work.
Myself, I just got a chance to try Poorboys Super Slick & Wax Car Shampoo in mine ( order to weather timing ), and it worked great. I had not adjusted my gun settings from using Gold Class soap ( which did not seem to work as well ) and it was night and day difference.
I filled the container ~ 75% full of hot water, added 4 Oz of SS&W and topped it off. I mixed it by swirling it around ( not shaking it ). Did the same thing with Gold class, and did not have as good of results.
Did the entire car with half a bottle left over, and I was not being overly efficient about washing it.
