Protect discs from splashes
To keep your discs free when painting paint, dampen newspapers with warm water or other paper with smooth edges. Then cover the slices completely with this paper. Nice close in the corners and it must be good. Due to the moisture, the paper sticks until the painting - at a normal pace - are finished. Then remove and you have no more work to scratch the discs free. Normal wiping is enough.
If you did not pay close attention when painting and you have oil or synthetic resin paint stains on the glass, remove alcohol or nail polish remover to remove. Leave for a few minutes and then rub with a cloth. It even goes from color, which is a bit older.
