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 :-) )
The conservatory is made from white uPVC, glass in all the windows, and multi-wall polycarbonate (smooth inside and out, but 'crinkly' between the smooth layers) for the roof panels.
Cheers Arfa
