Remember that vinegar should eat a little bit of the gloss if you put some. However, it would also eat the first thing layer of paint if damped too long.
Fortunately, I had MicroSet and MicroSol purchased a long time ago for $1 a bottle. Still didn't finish a bottle. In my honest opinion, MicroSet seems like vinegar and MicroSol seems like vinegar with a little bit of alcohol or ammonia solution.
Lastly, use a "disposable" brush because vinegar and softeners kill brushes.
