Hi all

I've got a "P" - form conservatory that goes right across the back of
the house, and sticks out 3m along the straight bit, and a lot more
at the 'bulge'. It's too wide at any point to be able to lean right
across, even on top of a ladder, to give it a 'bucket & sponge'
clean. It is a couple of years old now, and starting to get
algae-covered, and SWMBO has decided that this summer, yours truly is
going to get this clean ...
So I figured that I could use my pressure washer with one of the
extra long extendable wands that you can get for guttering cleaning.
I've just discovered that the pressure washer has a little pull-out
tube with a strainer on the end, to go into a detergent container
(Doh! that'll teach me to RTFM and know the capabilities of my kit
...)
So, anyone got any experience of getting this algae off ? Any
recommendations for a suitable detergent or whatever ? Is there a
proper stuff that anyone knows of ? I guess it has to be something
low-foam if you don't want the garden covered (I could always rig
some lights and play loud music if that happened :-) )

Pressure washers often dilute chemicals heavily. Commercial machine may
only allow a max 5% solution, DIY machine maybe double that, so its not
strong enough to develop much foam.

Just the water will shift algae, no need for chemicals.

Thanks all. Plain water it is then ! I will do the windows with my magic
e-cloths.
