Recommended Uses
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 to remove iron staining provided that any iron particles have been sanded out. It is suitable for use on all timber species including but not limited to Ironbark, Merbau, Spotted Gum, Western Red Cedar and Treated Pine. Timber which has been previously coated with pure Linseed Oil or some other similar finish may require light sand prior to the use of GREY DECK CLEANER. In this case, vigorous scrubbing with the Oxalic Acid solution will be required clean off the discolouration caused by mould.
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.

FAQ
Why isn’t it supplied in a liquid package?
Crystallised product added with water means that the small container has the same volume as a container 10 times its size. And who wants to pay top dollar for all that water?
Will it stop my deck from being slippery in the rain?
Yes, most of the weathering and mound, removed by Grey Deck Cleaner, makes the timber slippery when wet.
Can I use Aussie Clear Oils without prepping with Grey deck cleaner?
Yes, if the deck has dark spots best to apply a coat of GDC prior to using the decking oil.
