Hey, all good points guys. With this heat wave, of sorts, my shop has gone from 60 to 80 degrees.
I noticed a lot of the cardboard, even emptied get that stupid ring around the bottom, and you can wipe many times, and it comes back. I'm just going to put a napkin under, and leave them for a while.
Grease tins, I open and empty and wipe out as much as I can. There is never a perfect way to do them, as you can get screwdriver marks.
Ah, I love the hobby, keeps my busy. I have fun doing it, and love it.
Take care guys!!
