Couple irons I acquired

These pans have been in my family a long time. They have been neglected as you can see. I’m wanting to restore them and use them. The BSR is rusty all over. So far baking soda scrub hasn’t helped much. What do you suggest I try for the rust?

The Martin is not in bad shape at all. It has some build up on the bottom. I have gotten a lot off but I want to get it stripped down. I’m going to try the easy off yellow cap and see how that goes. What do you think?
