I have wanted for a while to try to use bleach as paint on fabric; today I noticed that my converse were falling apart, which gave me a good excuse to give it a shot.
The bleach doesn’t immediately corrode the dye, and the delay is a bit tricky to deal with. The other issue, which I expected, is that bleach tends to spread in the fabric, so it’s a bit difficult to keep clean lines.
The issue I had not anticipated is that it corroded the fabric, but also my poor brush, which was balding heavily after a few minutes of this experiment. Time to go plastic.
