Walex Commando Black Holding Tank Cleaner

Walex Commando drop-in sachets are the simplest way to clean your black holding tank. The super-concentrated formula breaks down residual waste and paper build-up from the tank walls and sensors.

Simply add one satchel to an empty tank and fill with water, soak overnight and flush. Your tank will not only smell like new but your tank sensors will read true. 1 satchel is strong enough to clean up to a 190L tank and is made from natural enzymes so is septic safe.
