Grey Deck Cleaner
GREY DECK CLEANER is a powerful wood cleaner, ideal for cleaning grey or blackened timber caused by weathering. It removes the stain, dirt and mould from timber. The result is a clean timber surface ready for clear finishing.
GREY DECK CLEANER is ideal for use as a deck wash for cleaning grey or blackened
decks and all other exterior woodwork. It can be used on all types of timber and is especially useful for cleaning blackened and weathered Western Red Cedar weatherboards. Timber that has been previously coated with Linseed Oil or some other similar finish, may require vigorous scrubbing with Oxalic Acid to clean off the discolouration.
Directions For Use
Dissolve 500 g of GREY DECK CLEANER in 5 litres of water (i.e. a 10% solution).
Using a stiff brush, clean weathered timber using the mixed solution.
Wash the timber down thoroughly afterwards with water or a high-pressure cleaner. This process may have to be repeated for timber that has weathered for some time.
Ensure timber being cleaned is allowed sufficient time to dry before application of oils or paints.
