Evening all,
Had a conservatory roof clean recently and the roof is under a large tree. There was lots of dried sap sticking to the roof and I couldn't remove it for the life of me — usually a coat of Virosol makes conny roofs easy after leaving it on for 5-10 mins but after 3 applications and endless scrubbing/rinsing with WFP a lot of it still remained. Any ideas how I can get this off? I'd try hypo but I don't want to stain the frames of the conservatory and we can't scrape it off as that would mean climbing on the glass.
Cheers,
