Cleaned  corrugated cladding about 18 months ago using pure water, it took a lot of scrubbing, any ideas i.e. different brushes' chemicals, to make job easier,.as we doing it again soon we use clx poles with standard brushes.

I use my conservatory roof brush (old brush that I dont use on glass), connect it up to the customers garden tap as it has a higher pressure. If its really bad use TFR (traffic film remover) that you can buy from your local motorist centre. Always use this stuff for roofs. Dilute it as instructed and spray on panels/roofs. Leave it on roof for about 15 minutes and then wash off.

I tend to use hot water also a hypo soap mix if required
