Introduction: How to Clean Paint Stuck in the Ferrule of a (fineart) Paintbrush
Hopefully it's possible to read the whole title. Unfortunately, I don't think this is worth it with bigger hardware store painting brushes, not sure it would even work at all if you're using anything that requires solvents. This is specifically aimed at artist's brushes.
Materials: Soap, Sewing Pin, Alcohol (if you paint with acrylics), Pointed Tool (palette knife will suffice), Flat Surface, Towel, Water.
I won't be covering the video again as an instructable because I feel it needs to be seen visually. It may feel long for something so simple, but I think the little things I mention are crucial. I did kind of ruin the first brush I tried this with because I was too rough.
