Keep your chemical toilet in tip top shape with Thetford Toilet Aqua Kem and Aqua Rinse range. Aqua Kem Blue keeps your toilet waste tank fresh and clean - its advanced formula breaks down waste, reduces odours and gas build up. Aqua Rinse Pink prevents the build up of limescale in the fresh water tank, thus ensuring a smoother flush that uses less water. Both products are double concentrated, meaning the new smaller bottles provide the same power as the old 1.5L bottles. The smaller size means the bottles are easier to store and require less resources to produce and transport - part of Thetford's commitment to reduce the environmental impact of its products.
