Why Water Hygiene Set?
The Water Hygiene Set is a thoughtful pairing of two key Iza Effect products for complete water system hygiene in your motorhome, caravan or boat. Water System effectively breaks down biofilm in the fresh water system — from the tank to the boiler and taps — while Fresh Tank neutralises unpleasant odours in grey and black water tanks and the toilet cassette.
By buying the set, you get both 900 ml products for a fairly lower price than buying them individually. Ideal before the start of the season or as part of regular twice-yearly water system maintenance.
