Hi
I'm cleaning the trad way and been going 1 month and have a question about the black marks sometimes that i leave on the frames.
When i scrim the glass/frame edges, the black rubber part of the frame glass edge is leaving a black mark on the scrim then if im not paying attention if i wipe the frame it leaves a black skid mark which doesnt come off the frame, well it probably would with a ton of arm aching scrubbing.
What can i do, obviously if i take more care when scrimming it will solve it but is this normal???
Ta chaps chapessess
