Doc Dave is right on. We did commercial blasting and powder coating. We bought this in 55 gallon drums, and injected it into a power washer. It is a fantastic product!

Buy this in 1 gallon jugs as Dave said called “Ospho”. I buy it at Home Depot in the paint section called Prep and Etch. Same stuff!!

Here is a video to help you understand.
