Walex Commando Black Holding Tank Cleaner CMDOB

Commando thoroughly cleans an RV’s black holding tank and sensors in as little as 12 to 24 hours without 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 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 tank for up to a week. For worry-free camping, use Commando preventatively every three months. Manufactured by Walex, the odor control experts.
