Never, never and I mean NEVER!! clean IEMs with alcohol, alcohol is a solvent and could damage the paint and/or the glue, I know you want to have clean your IEMs but alcohol is too strong better use some baby tissues or a degreaser for oily skin, at the end of the day that's the only thing you should clean your IEMs from.

You could try to re apply it to the nozzle but if you already ordered a new pair I don't know how much do you want to have 2 pairs of each filter.
