We have just Started doing Builders Cleans etc...
When it comes to cleaning the windows, we pull off the protective polythene sheet off the glass and find a lot of the glue left on the windows....
We have tried white spirit - which doesn't really work. (takes forever!!)
We are using scrapers, but am worried about scratching the windows, especially as it is still a building site and a lot of muck everywhere.
Is there a solvent we can use, or any other ideas out there???
Thanx
