The Thetford Aqua Kem Green Concentrated 750ml is an environmentally conscious toilet fluid designed for the waste-holding tanks of cassette and portable toilets in caravans, motorhomes and campervans.
Specially developed as Thetford's septic tank-safe alternative to Aqua Kem Blue, Aqua Kem Green provides excellent odour control while helping to liquefy toilet waste and paper for easier, cleaner tank emptying. It also helps reduce gas build-up inside the waste-holding tank.
The concentrated formula delivers effective treatment from a compact 750ml bottle, taking up less valuable storage space in your motorhome or caravan than traditional larger bottles.
Aqua Kem Green Concentrated is particularly useful when travelling to campsites or locations where toilet waste is disposed of into a septic tank, as Thetford specifically identifies its Green toilet-care range as septic tank safe.
For effective treatment, Thetford specifies a dosage of 75ml per 20 litres of waste-holding tank capacity, together with 2–3 litres of water. One dose provides treatment for up to 4 days.
