Iv got a Perspex ( plastic) bike shed roof at an office to clean tomorrow and it’s thick with green crap and bird crap all over it under some trees.
If I put bio washing powder in hot water and apply - how long would I leave it for before giving it a scrub?

Cheers in advance

Its pretty much immediate, 30 seconds to a minute is more than enough if its just biological matter.
