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.
