I used pickling vinegar for dyeing recently when I ran out of my usual acid mordant… I couldn’t find any other white vinegar in the shop I was in and figured it would just make the silks smell slightly different til I washed them!
I use 50/50 cheap malt vinegar & water in a spray for cleaning the bathroom sink & mirror. It’s great. It cleans the mirror really well. So long as you wipe it off quickly it doesn’t seem to leave residue, though if you let it dry it will.
