      “All I can say is wow! I use Hydro-Chem products now and will never use any other brand of soap again! I’ve been washing trucks for 13 years and switching over to using HCS’s soaps has been the single best decision I’ve ever made without a doubt.”


      “Hydro-Chem is the best of the best. If you’re in the pressure washing business I highly recommend contacting or visiting their facility for all your chemical and equipment needs. Hydro-Chem sets the bar with their detergent solutions, you cannot find better cleaners at better prices anywhere.”

      –Scott Schumacher

      “We were nervous at first, but after our first dump truck we cleaned, my shoulders, body, and the scrub brush were grateful we took the time to call these guys. We have never been happier or more profitable.”

      –Ruben Paredes

      Excellent customer service! Their chemicals and their 2-step gun are the perfect combination for fleet washing. We couldn’t be happier with their products.

      Ron Mccain

      “Hydro-Chem has been very helpful since the first day we walked through their door. They are very knowledgeable about soap and seem to have whatever we need. I look forward to a long-term working relationship.
