Holding Tank Cleanser (12 Sachets)

This holding tank cleaner will clean any RV or marine toilet bowl and control holding tank odours with one easy to use sachet.
Place one sachet in toilet and the effervescent action will quickly dissolve the sachet, releasing enzymes and cleaners.
This product is 100% biodegradable and formaldehyde free.
It is non-toxic (unlike bleach and other supermarket toilet cleaners), non-staining, and includes enzymes that work with the natural enzymes in waste to encourage speedy break-down of waste and toilet tissue for thorough tank discharge.
