A friend just suggested using caustic soda to clean the paint off a plastic model kit that I want to repaint *. What I want to know is, what is the stuff, and how toxic is it? Can’t be too bad, as the stuff I used was sold as Espresso maker “shampoo”.
*It worked fantastic! One tbsp/pie plate of warm water, soaked 10 min, paint came off like magic. Only had to scrub panel gaps lightly with a toothbrush. Didn’t harm the model plastic at all. Paint was Tamiya Acrylic.
