Question:

Can i clean my skateboard bearings with 50% alcohol?

or witch hazel? im just looking through my cabinet and seeing what i have....

Answer:

Im not sure.. That could probably ruin the bearings.. That could cause them to rust up over time. I say just wipe clean them with a rag.. maybe if you spray just a little WD -40 to loosen up the dirt would be ok. .. They sell this bearing lubricant at skateshops. That would probably be ur best bet... Bones also sells this speed cream for bearings... If you got good expensive bearings like Bones then i would suggest you taken care of them buy special made products to clean keep your bearings lubricated.. Me my self got a mix of bearings , Lucky ,black panthers ,black widows .. So i don't really care i just spary a little WD-40 to wipe the dirt of clean them .. Though i heard that Wd-40 tends to rust up bearings .. But i just use a little my bearings are cool.. Had them for a while now no rust.. ..
my god, both people just told you to use wd40.... jesus christ... do NOT use wd40!!!!!!!!!!!!! ideal way to have your bearings get ruined. 50% alcohol is a little low, could have impurities which can ruin the bearings as well. your best bet is 70%+ isopropyl alcohol (preferably 96% or higher). it really only costs 3-4 bucks. also gasoline works to clean the bearings. then once they have soaked in there for a long time buy some bones speed cream, and apply one drop to each side. never, ever use wd-40 on your bearings. they will speed up temporarily and then get wrecked.
i cleaned my bearings yesterday and i used an air compressor to knock the dirt off then i spin my wheels as hard as a can and apply WD-40 while they spin, then i spin the wheel for bout 10-15 seconds so it sets in wipe of access then ride! ( do this for each bearing and or side)
