About Kleen Tank
Kleen Tank is a mobile RV tank cleaning service based in Sycamore, Illinois. They travel to you, using hydro jetting to clean and flush black and gray holding tanks. That means no hauling your rig to a shop. They also handle fresh water tank sanitation and hot water tank cleaning. Reviewers often mention how thorough the cleaning is. Many say the techs took time to explain the process and how to maintain tanks between visits. Sensors reading wrong and lingering odors come up a lot in reviews, and customers report both improved after service. One reviewer said a tech even replaced a water heater anode rod. They serve northern Illinois, southern Wisconsin, and northwestern Indiana, including the Elkhart County 4-H Fairgrounds during RV rallies. With a 4.8 rating from 128 reviews, they seem to do right by RV owners. Call 815-508-3878 or visit their website for scheduling.
