摘要

The invention concerns a method of cleaning objects contaminated with fresh paint and/or varnish, using a hot paint-removal agent. In order to be able to regenerate the paint-removal bath economically, without significantly reducing the proportion of active substances it contains, the invention proposes that the aqueous paint-removal bath is regenerated by microfiltration. The bath liquor is passed, without significant cooling, across a ceramic membrane at a given minimum flow rate and a given minimum cross-membrane pressure difference. The material retained by the membrane is discarded.
