Haha I bought about ten of them for about £15 that's like 11 dollars to you folks so I still won no matter what!
I'd take a risk and dip it really quickly in either MS-70 or e-Z-est. Both are coin "dips." If you decide to do this, make sure to dip them for a very short amount of time and then rinse w/ distilled water.
You can dilute the ez-est with distilled water for a less drastic effect and gradually increase if necessary.
Typically when people use the term "dip," they are referring to an acid based product like EZest. MS70 is basically lye (strong base) with surfactants.
