Hi Guys,
Has anyone come across yellow staining on polycarbonate roofs as have seen a few recently and would like to try and remove it ;)
It seems to be only on sections of the roof and appears to be where the water runs down from the top cresting/cover!!!
Cheers

dont think you can remove it , i have done a few recently where 1 complete panel has turned yellow , all the rest are clear, think it's something to do with uv

just baffle them with science m8, i havent come across it to be honest! there isnt alot of pressure you can get on a con roof unless you have a ladder and i wouldnt personally use one anyway,as you can cause broken seals etc. spray raffic film, and if that doesnt work use a cream cleaner with a used green pad and if that doesnt work just explain to customer that it is impossible to remove. u can use cream cleaner via a waterfed pole with a strap and it works a treat. i have never had a complaint, and this kind of work is on the increase/..

Alan...it is exposure to uv rays that causes it.Why it happens on some sheets and not others is still a mystery to me,but not a lot can be done about it. :)

Hello Alan,
I'm have to agree with everyone else. It is definetly down to uv rays bleaching the polycarbonate panels.
I would just tell the customer that you do get the odd faulty panels.
I do plenty of conservatory roof cleans, with no problems.
Hope this has helped.
Kind regards. :)
