New Elsan Organic toilet fluid has been developed with brand new biological technology which works in a completely different way to conventional toilet fluids. By dissolving waste and removing odours naturally, the chemical smell that has long been associated with caravan toilets has at last been eliminated ...and replaced with a delightful mild fragrance. Moreover, Elsan Organic can be used in both flush and waste tanks which makes things so much more convenient. Because it is environmentally safe and free from harsh chemicals, waste can be emptied into a septic tank. Not only will Organic make your toilet a better place, but you’ll be doing your bit for the environment too. The toilet flush fluid is concentrated meaning that a 60ml dose is required for every 10 litres of fresh water.
