I just went to look at a 5 bed detached house, and while the customer was away they had a firm in to spray paint the roof tiles, and clearly didn't give a damn where else they sprayed!! They're suing the firm. Anyway, this fine red terracotta spray paint is all over the 'lead' windows!!! Any idea's on: 1. How to remove the stuff off leads, rather than scraping each and every diamond cut glass which will take me forever?? 2. How much?? 5-Bed Detached - Uxbridge, Greater London. Cheers in advance.
