I recently put a post up on how best to prepare wooden fence for
re-staining ....... I had tried Sodium Hypochlorite & Lauryl
Dimethylamine Oxide - which was excellent at cleaning my sandstone patio.

However there was concern about bleaching effect on the wood, removal of
colour from existing stain, and how this could effect longevity of new
stain.


Did a lot of Googling around and came across a product recommendation
.... 'West & Forget'
I managed to get a sample to try ..... diluted 5 to 1 ... simply
sprayed it on ... no agitation whatsoever.
All algae dead the nest day ..where it was thin ... simply gone, where
it was thick, what remains is a white powder.

This can be brushed off or it will wash off in teh rain.


Impressed how well this performed. It contains no bleach and has
unlimited shelf life ... as it also works on brick & stone I just
ordered 20L of it ... and will spray my cills, lintols, pillars & copings.
As well as all fence (6000 sq ft) and the patio to stop re-growth.

It seems it is well advertised on the TV shopping channels - I went to
manufacturers web site .. and their price was the same .......... but
importantly there is also a 20% scheme if you recommend someone.
Applies to both party's.

(happy to recommend any of you if you want the 20% off - ping me an
email)

I used that and saved a nice chunk of money.
