i used it on all my kitchen cabinets before i sanded and painted them and it didnt damage them at all. i even used it on the handles and hinges (put them in a bowl and sprayed,then washed in hot soapy water-you would not believe how clean they came- they were silver looking but wow how clean! i tell you the people who had this house before us must have never cleaned.lol.. it tells youonthe bottle what to not use it on,includes wood,leather,laminated etc. Greased Lightning - Cleans when others Can't .hope this helps, we had nothing to lose because we were painting them anyway,but it worked great and did not damage at all.
