I have a late 50's early 60's IH Fridge. Its been all all torn down and I am in the process of rebuilding. I took out a considerable amount of yellow fiberglass insulation. It had gotten wet and was a bit musty. What insulation is safe to put back in..can I get jut anything from the home centers? I've seen a few threads which talk about rock wool or mineral insulation....does anyone have specific examples or experience with these types of insulation? Thanks for the help!
