Walex Commando Drop-ins Black Holding Tank and Sensor Cleaner – 12 pack
$24.99
Commando Black Tank & Sensor Cleaner is an easy-to-use quick-dissolving packet filled with a super-concentrated, scientifically natural enzyme formula that cleans tank walls and sensors and lubricates valves and seals. Residual waste caked to the tank walls creates foul odors and false sensor readings. A malfunctioning sensor is one of an RVers’ most frustrating issues because they don’t know when to empty their tank. One packet of Commando cleans the tank and restores sensor function in as little as 12 to 24 hours—no agitation or scrubbing required. Walex recommends the preventative use of Commando every three months to help keep the black tank in good working condition. Commando is now available in recycle-ready packaging. Customers can recycle the empty pouches in plastic bag recycling bins, thereby lowering their impact on the planet they love to explore.
