Allright, so i was reading some old threads about water damage from someones signature and i read that you can use a qtip and Vinegar Oil and rub it on the titmus paper and it will make it turn white again? does this actually work? and if it does can anyone explain it to me? i would think that the liquid would just set it off. also im not interested in trying to basically commit fraud. i dont even have an ipod at the momemt cuz mine was stolen so im waiting for the September 1st event to get all excited about the new one! im jsut interested if this actually works and if anyone can testify for it.
