Century Chemical RV Water Holding Tank Treatment

Nearly a Century of Holding Tank Expertise

Century Chemical has been producing sanitation solutions since 1926, and their legacy in the RV world runs especially deep. RV water holding tank treatments are at the very heart of what this Elkhart, Indiana manufacturer does — and with flagship products that have been trusted by RVers for over 55 years, it shows. Whether you're a weekend camper or a full-time traveler, Century Chemical brings a purpose-built lineup of holding tank treatments designed to eliminate odors, break down waste, and keep your black and gray tanks functioning cleanly on the road.

Flagship Product Lines for Every RVer

Century Chemical's holding tank treatment portfolio centers on three distinct product lines, each targeting a specific type of RV user and preference:

• Travel Jon® Holding Tank Deodorizer — The original and most iconic product in the lineup. This highly concentrated liquid blue formula requires just 2 ounces per charge, making it an economical go-to for controlling tank odors. It's non-formaldehyde, biodegradable, and safe for all septic and municipal systems. Available in multiple sizes from 8 oz up to 1 gallon to suit any trip length.
• Supreme Green — A more recent addition to the portfolio, Supreme Green is an enzyme-based treatment available in both liquid and convenient water-soluble toss-in packets. Infused with a eucalyptus fragrance, it uses enzymes to break down solids, eliminate odors, and even lubricate drain valves. Tubs come with 36 water-soluble packets, making it a smart choice for full-time travelers looking to reduce waste and simplify tank maintenance.
• Blue Max — Century Chemical's Blue Max line includes both traditional toss-in packets and a fan-favorite Glitter Glamping Edition, giving glampers and casual RVers a fun, effective holding tank treatment option. The formula delivers superior odor-fighting and cleaning power for RV and marine holding tanks in an easy drop-in format.
