Walex Commando RV & Marine Black Holding Tank Sensor Cleaner with Ocean Mist Fragrance - 4 Treatments

Commando thoroughly cleans an RV's black holding tank and sensors in as little as 12 to 24 hours, eliminating the need for scrubbing or agitation. Commando uses powerful enzymes to remove residual waste and paper caked to the tank walls and sensors, eliminating foul odors and restoring sensor function. The super-concentrated formula liquefies solids, restoring the tank to like-new condition. To use Commando, empty the tank, add one packet of Commando, fill the tank with water, and let it sit for 12 to 24 hours before dumping. For stubborn odors, Commando is safe to leave in the tank for up to a week. For worry-free camping, use Commando preventively every three months. Manufactured by Walex, the experts in odor control.
