We are painting indoors and my son used the downstairs wash sinks to rinse our brushes and roller. He had hot running water and a bucket to let them soak in but when I went to do wash last night the sink was still almost 3/4 full of water (from about 3 hours earlier).
I am thinking more paint got in then he thought. He did rinse the roller brush directly in there and that was a bit of paint on it.
I used a plunger and ran hot water again. I even used some baking soda and vinegar.
About 4 hours later it was down to just an inch above the drain.
This is a rental so I would like to get this working again.
I wondered if there was anything else to dissolve the paint. I was not certain about plumber's helper or such.

I would suspect that it's something other than paint. We use our kitchen sink to wash out brushes and have never had issues with it clogging. You would have had to have washed a lot of very dried out paint down in order for it to have clogged.
If plunging hasn't solved the issue, you could try any of the chemical drain cleaners, or you could try a snake or auger. Hand operated snakes are fairly inexpensive and are handy to have around in general and don't have any of the drawbacks/concerns that people have with chemicals.
