As toilets are housing human waste, toilet additives are required to keep it both sanitary and to reduce odours. Two different types of liquid are used for this purpose.
Top Tank Liquid: This pink fluid is mixed with water and placed in the top tank. It provides a fragrant smell and puts a non stick coating on the bowl when flushed.
Bottom Tank Liquid: There are two different types of bottom tank fluid which offer different levels of speed in breaking down the waste.
- Green Holding Tank Fluid: Lasting between three and four days, this fluid biologically breaks down waste. For this reason it is regarded as the more environmentally friendly option.
- Blue Holding Tank Fluid: Lasting between four and five days, it has a fresh fragrant scent but should always be emptied into toilets or sewerage systems.
For this particular cassette cleaner the dosage is 300mL per 10 Litre holding tank capacity, just add 5 Litre's of fresh water and shake tank to cover all surfaces, leave for a minimum of 16 hours before emptying.
