We have a plumbing and electrical business in Northwest Iowa. Five years ago, we were introduced to Oxy Blast. The first time we used it was on a cattle farm. Before Oxy Blast, every six months we would blow out his lines because of the iron and rust build up. The Producer started using Oxy Blast and we have not been back since to blow out the lines or to pull the pump. We recommend Oxy Blast to all our customers.
