Looking for a way to inject detergent into a pressure washer that will spray from the wand at high pressure.

Not sure this idea will do what you want,but you could try rigging up a syphon style nozzle to it,similiar to the principle wash guns use

There’s two completely different gadgets shown in this thread, I use both depending on situation. The injector from the first post runs chemical/soap through the high pressure line and out the conventional pressure washer wand. The soap goes on like water and mostly sheets off.

A foam cannon replaces the nozzle on the end and injects air along with soap to spray low pressure foam with lots of lather. It sticks to the surfaces for a lot longer.

Neither will work well generally with small 120v electric washers, because they don’t generate the pressure and flow rates required. When I use one, I break out the big gas powered washer.

I have seen reports of people making a cannon work with less flow by replacing the orifice inside with a smaller one. I haven’t tried it.

The primary focus of the discussion is about a soap inductor. I’ve got the foam cannon stuff figured out, and even though my pressure washer doesn’t put out that much volume of water, that foam cannon I bought, like I was telling somebody else, came with two different orifices which actually does make it work pretty good.

Yeah, that could possibly do the trick and I thank you for taking the time to find that but I’m not sure if that would work with my little undercarriage sprayer contraption.

I’m probably just gonna have to go with the fertilizer sprayer option.
