Found 8th Aug 2010
does anyone know how to get mortar off upvc with out it ruining them? the house we moved into has had all the front re-rendered and the builders got mortar over the upvc and didnt think to wipe it off. Ive tried everything in the last 5 weeks even scraping it with my nail which got some off the glass but not the upvc,
the window company said hot soapy water and a scourer but i dont think thats a good idea surely it would scuff the upvc?
any ideas here guy would be great

have you got a jetwash? or even a steamer? they should work!
steamers work even on artex.
sorry cant edit for some reason
pressure washer wont damage glass
my o/h uses pressure washer on all our upvc and windows. Hasnt caused any damage.
you can also get upvc cleaner which is non-abrasive and brings it up sparkling

You can use a scourer, just use one that's suitable for non-stick pans and not the abrasive ones. Elbow grease as well.

problem there is that the grit in the mortar is abrasive

pressure washer is ideal for first attempt
for the glass

for the pvc,
If you have a blunt wallpaper scraper and butter knife, use the blunt scraper on all of the flat surfaces and use the blunt knife in the sculptured hard to get areas. once you have got the thick of it off, try a good cream cleaner and plenty of elbow grease.

Aye, fair point - should have said to remove the worst of it first.
