I was cleaning one of the rocks that came with a second hand tank I bought awhile ago and noticed what I'm pretty sure is paint.
I had some vinegar on them last night and then they were soaking in a diluted mix of vinegar and water and it won't come off with a scourer
Aesthetics don't matter I just want to know if they're safe.
So, how can I tell if they're safe?
Edit: Sorry if I chose the wrong section, if so can a mod please move it.
