ᐅ Washing paintbrushes, nitro thinner, and other related materials

Hello everyone,

I am a trained painter and varnisher and had to work with primer today. Since I didn’t have an old brush available, I had to use a good one of mine, and well, I just tried cleaning it with nitrous thinner, but it doesn’t dissolve at all. Is there a way to clean it? Because if nitrous thinner doesn’t work, that’s a bit strange. I mean, okay, I had to dilute the primer with spirits, but unfortunately, I don’t have any at home right now to try cleaning it with (if that even works).
If anyone knows something, please let me know 😉

Best regards

and what do you use for that? My boss didn’t know either.
A coworker said something about a special thinner. Or is that nonsense too?

The solvent in the paint material is always suitable.

So with denatured alcohol, it should be soft enough to work with again?

"Brush cleaning" should be done while the brush is still soft and the coating material hasn't dried in the bristles. If the bristles or hairs are already hardened, the brush generally needs to be discarded.

They’re still not hard, not even today. Just slightly dried on. But why has all the nitro disappeared? I had filled the small bucket up to one-fifth (20%) after all 😉

You can’t know everything, right? But here’s a different question: would it help if you soaked the brush in a strong paint stripper and covered it with plastic wrap overnight?
