i got a free bike today from my college campus that i want to make into something dandy for the little lady
shes not a hardcore skidzz kinda person, more like a leisurely mile around the park and im done type, so this walmart hybrid/whatever bike will be fine


question is: how do i get this nearly solidified grease off everything that is supposed to move? should i douse it with wd-40 and get my scrub on or is there some kinda awesome solvent i could just soak it in that would make life easier?

sub question: aside from fleamarket/garage sales is there a reliable source for walmart quality bike parts, namely 26" front wheels and a seatpost?
