I'd like to use my HF pressure washer but don't know what to use in the soap dispenser attachment.

 

I have Karcher pressure washer and used NXT soap dulated in water before. But now I just use my Karcher for the wheels and tires. I do the two-bucket wash method to protect the paint of my ride.

 

Adam's has a very good car soap. Buy at Detailers Domain.

 

I use Adam's as well and buy it from both Adam's directly and Detailer's Domain.

I love it when used traditionally and when used in my foam cannon with a pressure washer it's like washing with real slippery shaving cream.

 

Buy a pressure foamer, Snow foam soap, almost don't need to wash by hand unless very dirty.
