I have a new to me cast iron pan my mom found for me at a garage sale. I scrubbed it many times but everything cooked in it tastes "off". Also the lid has an almost waxy coating on it. It is in great shape and seems seasoned but now I am leery of using it with the strange flavors. I have no idea what they used on it so now I would like to strip it and start over. I know how to re season but any suggestions on how to strip it clean? Any help would be appreciated! I really like the pot and it's exactly what I was looking for. It's about the size of a 12" skillet but with tall sides, a regular handle and small handle on the other side, no brand on it though.
