Undercarriage Wash System

With the need for trucks to have the undercarriage sanitized and/or the salt removed…

…HCS has developed an undercarriage wash that can be placed anywhere you have electricity and water without the need of cutting in a trench to clean and disinfect the underside of your vehicle.

How Does It Work?

We offer 2 separate models with different volumes in each to meet your needs.

The combo unit typically would use a moderate volume of diluted sanitizer that would be pumped through the undercarriage while it is washing the underside, and the wheels of your truck. This unit would use one module.

The upgraded option includes 2 modules; the first module has an upgraded pump for washing more debris off the underside of the truck, and the second module uses a low volume of sanitizer to disinfect the truck.


“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.”

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

“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.”

“The Hydro-Chem team is the best you will find. We worked with them to design, install, set up, and bring our new school bus wash system online. The wash system performs as promised and the support since the install has been over the top.”

–Troy Bearman


“From the design phase, installation phase to the setup phase we couldn’t have been more satisfied! Everyone working with us was extremely knowledgeable, helpful, and willing to go the extra mile to ensure we were satisfied. Our 2-step drive-through system has already begun to show its positive effects in just two weeks and the soaps we used with our 2-step system work like magic!”
