I've been using nail polish remover in exactly the same way as you for years.
There's basically two types; with and without acetone. Oddly enough the one - alledgedly- without acetone works almost as well even on resin models.
Rinse the models with water afterwards because the product keeps active for a while.
My wife buys me 'paint remover' - almost every time she goes shopping for nail polish, eye shadow or lipstick and such.
My previous batch was a horrid pink, the one I got now a ghastly baby blue
