Most machine shops and dist. charge around $65.00 per hr. I have to drive 1 1/2 hrs to my dist. He charges $85 if you don' buy chemicals, $75 if you buy chemicals. $65 and hour if you buy $50 of chemicals. I always buy from him and he does all my work. I don't buy too much chemicals from him, cause they changed the detergent and it clogs my machine. Go ahead and blast me. It clogged so bad I had a hard time getting the orffices out. He charged me $85.00
