Founded in 1981, Chemwash took to the exterior cleaning industry with a revolutionary new cleaning technique. In those days, the norm was high pressure water blasting, which is often damaging to surfaces. Chemwash’s solution was to use non-toxic detergents to do all of the ‘hard work’, followed by low pressure and fan washing procedures.

The detergents were developed for Chemwash by a leading industrial chemist, with a very specific brief. Firstly, the detergents needed to be safe to use around houses, buildings, people, pets and vegetation. Secondly, they needed to be effective in removing dirt and grime, while selectively killing mould, lichen and moss.

Since then, Chemwash have continued to research and develop new exterior cleaning products, remaining on the cutting edge of safety and environmental sustainability.
