…and spent 4 hours cleaning them. They had been stored with ink on them.
I cleaned the ink off before stripping the emulsion. All but one came clean, though all have some hazing that hasn’t come off even with an application of the haze remover. I think I need a finer bristle brush. I’m also going to try to use my pressure washer and see if that has any good effect on the remaining emulsion and hazing.
I probably should have just bought new, but it’s been a learning experience. I only needed a few but I bought six expecting some duds. So far it looks like I’ll end up with six.
