Deck cleaner

RENSA TERRACE is a very efficient detergent for washing of wooden terrace floors and garden furnitures before wood oil treatment. It removes dirt, mould, algae growth and other impurities that prevent the wood oil from absorbing to the surface.

RENSA TERRACE can be used on all wooden surfaces which endure cleaning with water and will be treated with wood oils, wood stains or exterior paints for wooden surfaces. RENSA TERRACE is strongly alkalic detergent, which mattens painted surfaces. It can also be used for pre-treating very dirty and chalked painted surfaces before maintenance painting. RENSA TERRACE is environmentally friendly and biodegradable. It meets the requirements by OECD and by the Detergent regulation of European Parliament and the Council on detergents for biodegradability of all used raw material (OECD 301B, EC 648 / 2004).

Directions for use


Wet wooden surfaces with water before applying the detergent. This prevents the detergent from absorving too much and drying too fast. Apply the detergent to the surface to be cleaned by using e.g. a brush or low-pressure spray (so-called garden spray). NB! Avoid splashing – the detergent may damage painted surfaces. Let it act for abt. 5 minutes. Enhance the cleaning effect by brushing. When the detergent has acted, it creates a slippery surface. The detergent must not dry on the surface to be cleaned - wet the surface again with the washing fluid, if needed. If the dirt has got very embedded, a second treatment with RENSA TERRACE might be needed. Rinse the surface thoroughly with clean water. When using a pressure washer avoid excessive wetting of the wooden structures, such as weatherboards and outer walls. Let the surface dry for about 24 hours before painting or other treatment.


Must not freeze.
