I did a quick search and didn't see anything other than a suggestion to use WD-40. I'm below-novice when it comes to restoration, so I'm asking you professionals for some help. Is there a general consensus as to the best way to remove rust from the screws on figures? Is WD-40 harmful to the plastic or should the screws be removed first and then cleaned (seems logical)? Also, instead of cleaning, has anyone found that G1 figures, in particular, use a typical sized screw that can be purchased at a hardware store and used in lieu of cleaning? Thanks in advance for any and all suggestions!
