When your black tank sensors stop reading correctly or you’re dealing with lingering odors, it’s time to call in Commando. This super-concentrated, enzyme-powered cleaner is formulated to tackle the toughest buildup on tank walls and sensors - no scrubbing required. Just add one dissolvable packet or one dose of liquid into your RV toilet, fill the tank with water, and let it sit. In as little as 12 to 24 hours, Commando breaks down residual waste and paper, restores sensor function, and leaves your tank clean, lubricated, and ready for your next adventure. FEATURES - Restores black tank sensor accuracy: Breaks down residue buildup on sensors to fix false readings like “2/3 full” issues. - Super-concentrated enzyme formula: Digests tough waste and toilet paper buildup without harsh chemicals. - No scrubbing or agitation needed: Just drop it in and let it go to work—perfect for hassle-free maintenance. - Cleans tank walls, lubricates valves and seals: Maintains the entire system, preventing long-term issues like clogs and stuck valves. - Formaldehyde-free, biocide-free, and septic-safe: California compliant and safe for all black holding tank systems. INSTRUCTIONS FOR USE Empty black holding tank and close valve. Add one (1) Commando packet into the empty tank and fill the holding tank full of water. The water level needs to cover all sensors to allow Commando to penetrate and clean any buildup off the walls and sensors. Let product sit in tank for 12 to 24 hours. Driving the vehicle to agitate can help speed up the process, but is not required. 12 hours is sufficient to break down most waste and paper buildup, but extreme cases may require letting the tank sit for 24 hours. One (1) Commando packet will treat a holding tank capacity up to 150lt.
