After I used my Hardline molds the first time, I put some Bullplate on them as it was handy on the bench at the time. I was told not to use it in that way and to remove it with acetone, which I did. I then scrubbed with Dawn and let dry. I didn't bother with them for a few days. Yesterday when I was moving them to use the bench they were on I noticed some rust on them. It was only in the grooves where the handles go and in the set screw holes. I put some oil on them yesterday and left them on the bench. I haven't checked today, but if it is still there, what is the best way to easily remove it? I don't think it is a big problem because it isn't in the inside of the mold, but would like to take care of it.
