pu foam removal

[tchook]

used expanding foam to fill gaps around upvc windows. Removed excess foam but don't no how to remove cured foam from the frames. Tried a paste from Everbuild but that didn't work at all.
Any ideas welcome

Try getting the sharp end of a Stanley blade as flat as you can to the frame and scrape the frame. Try not to gouge the frame and ensure that the blade is new and not serrated or jagged.
