We have been manufacturing Biosafe toilet blue additive for the past 14 years. It has been formulated to stay fresh and maintain its colour for use in a typical building site toilet used by up to 7 persons over a normal working week without degrading. Biosafe is equally suitable for use as an event toilet additive
Biosafe is Formaldehyde free and is available in a wide range of perfumes including Berry, Citrus, Cherry and Old Spice. The product is supplied in a 1 litre bottle with a built in optic so that the appropriate dose can be accurately measured.
Biosafe works extremely well in the bottom tank of cassette toilets usually found in Caravans, Motor Homes and Boats. Our extensive tests have shown that it will out perform all other toilet additives widely available from Caravan Shops and Boat Chandlers
User instructions…. Measure and pour Biosafe directly into the effluent tank. Add water afterwards to disperse the chemical
Plastic site and event toilets 50ml charge to 20 litres fresh water. Increase the dose up to 100ml if heavy use or higher than normal ambient air temperature is expected
