Something i posted on matts forum this evening .... pictures and how i clean a conny .... hope it helps
Was an hour to an hour and half for the roof - pointy bits, pannels & roof bars (i did have to go round the neighbours to do one of the 3 sides)
The gutters took about 35 mins with a hosepipe and a brush from a dustpan and brush set (thats still in the van - dont tell my wife).
Trick is to be generous with the virosol ... the conservatory in the pictures was a 3 pannel x 3 pannel and i used 5L of virosol mixed to 1:24. That might seem alot, but 1 x 5L concentrate bottle makes 125L.
Spray from the top (pointy bits), spray down and leave for 2-5 mins depending on sunshine / heat (2 mins if hot / 5 mins if cloudy).
I use a vikan flocked sill brush (very soft brush) to clean the roof. Spray a little water on the roof (quick zig zag motion) and then start cleaning from the bottom upwards (start closest to the gutter).The sill brush helps as it has a larger surface area compared to say a superlight. The chemical will foam up a little, this is what you want to happen.
Once you get to the pointy bits at the top, the sill brush has another use. Sill brushes have two sides to the bristles. This means you can sit one lot of bristles on the ridge and the larger set of bristles to clean the pointy bits. By doing it this way, you dont have to hold the pole up - you just rest it on the ridge and mover it side to side.
Once you have done this, then rinse the roof off with custys hosepipe. Quciker than using wfp (you can do a final rinse later if you want to with wfp)
Once i have done the roof then i move on to the lips where the water runs into the gutter. Easiest way i have found to do this is buy using a cloth. Sometimes you can take the plastic strip off, sometimes you cant. If i can i do as i find its easier to clean then
Then i rinse the roof again with the hosepipe and clean the external gutters and windows.
If they want the internal gutters cleaned out, then its extra - this one i think i charged an extra £25 just for the internal gutters. If im doing the internal gutters then i do this before the final rinse on the roof and before the windows on the conny.
First thing to do is to get any crap out of there. I have tried various scoops, but its easier & quicker to take a bucket up and scoop it out with your hand - gross yes, but time is money and all that.
Once you have scooped out the crap, then i use the customers hosepipe with a hoselock sprayer (plugs into a female hoselock and you twist it to move from a mist to a jet). First thing is to spray out any crap left in there. Next spray the gutter and use the brush from a dustpan and brush set to clean to white.
Hope this helps mate ... has taken me a while to figure out how to get the perfect conny roof clean .... this is my method and it does the job !
