Be it on the road or back at home, the Duo Tank Cleaner Concentrated 800ml from Thetford is your secret super-power for making light work of a dirty job.
For periodical use in both your waste holding and grey water tanks, this cleaner removes crusty scale build-up and grease deposits. It has a fresh citrus fragrance, thoroughly cleaning all the nitty-gritty for you. Simply ensure your tank is empty before adding 200ml to 5 litres of water for a waste holding tank, and 600ml to 50 litres of water for the grey water tank via the sink or shower drain. With better-performing Lukewarm water, shake your waste holding tank before taking it for a drive to mix the solution thoroughly, covering all surfaces inside the tanks. Leave for at least 16 hours - and voilà! All without a single scrubbing brush.
Ideal for RVs, caravans, and motorhomes, Thetford’s Duo Tank Cleaner Concentrated 800ml does all the hard work for you - so you can look like the hero without busting your butt.

Cleaning black water tank1 answer
I have a 200 litre black water tank in a house boat if I add 800ml to a full tank of water (200Lt) and leave it for a week will it work?

G'day Steve,
It's possible that this may work out, however we've got no experience with houseboat black water tanks, and the requirements for tanks of this size. We'd recommend reaching out to a houseboat supplier/repair agent as they may be able to advise a suitable product.
