Founded in 1981 and 100% kiwi owned, Chemwash is a leading pioneer in the exterior cleaning industry. We were the first company in New Zealand to use the combination of low water pressure and biodegradable detergents. The Chemwash cleaning system is extremely versatile and safe, specialised for all exterior surfaces. That means we can produce great results, with no risk of damage to your property.
