Thanks Randy,
What tip I should use for high pressure soap in self serve car wash. I want it to come like milk and how much foam additives I should add in 55 gallon drum.
What is the easiest way to mix powder soap . Do you fill 55 gallons drum with hot water and then add 50 Ib simnoiz correct powder into it, or you do in small batches . Do you need to stir it or just close the cap and shake or roll the drum?
