As your portable toilet is housing human waste, it is essential that you keep it clean and reduce odours, so that you can travel comfortably. Thetford’s Aqua Kem Blue Additive is the perfect product for this. It is an efficient toilet additive that helps eliminate unpleasant smells and reduces gas build-up. It works by liquefying waste and breaking down toilet tissues to prevent clogging. Detergents also clean tank walls and drain lines, to ensure there are no lingering smells. This product is easy to use, just add 75ml per 10 litres of tank holding capacity, and dilute with 2 to 3 litres of fresh water. Make sure you replace the liquid every 3 to 4 days to ensure it lasts. Due to the high quality of this product, it’s no wonder Aqua Kem Blue is the world’s best-selling toilet fluid.
