Kent asks:

“I want to strip the paint from one Atlas and one much older blue-box Athearn. I read to use 91% isopropyl alcohol but wondered how safe the stuff is, do I just soak it in a container of some kind (for how long), and/or scrub it (using what)? I would do it right rather than guess. Thanks if you can help.”
