I'm only talking about unclicking the row with the faulty board, takes about 10mins, both ways work, just a matter of preference
Wd40 will dissolve the wax, if that's what's causing the shine, then a bit of soap should get rid of any residue of wd40, there will probably be something online
Anything you put on it will probably stand out just as much as the shine when the light hits it,better to just go for the replacement
