Single edge razor blades for glass, putty, and scraping
There’s no real substitute for a fresh single edge razor blade on restoration work. It cleans dirty glass, shaves off old glazing putty, and scrapes away the general gunk that builds up on an old window. The single edge gives you a dull spine to grip and bear down on while the sharp side does the work.
They go dull with use, so buy a pack and keep a few on the bench. When one stops cutting clean, swap in the next.
