Question:

WD-40 on skateboard bearings?

I got a set of bones reds skateboard bearings about 5 months ago and i heard that theyre really fast. but they have been really slow ever since ive got them. today i squirted wd-40 inside the wheel over the bearings and span them for ages and they span for ages really fast. i heard wd-40 is bad for skateboard beasrings though? i only go to indoor skateparks with it so they dont get that dirty

Answer:

Wd40 Skateboard Bearings
Common mistake. WD-40 is a penetrating fluid; it dissolves oil and grease. You need to re-grease the bearings.
WD-40 will atract any sort of dirt dust and will slow down your bearings. You should take each bearing apart and place it in something like nail paint remover, then buy some lube from your skate shop! works everytime
Wow! Good answers all around! WD-40 made for NASA like in 50's or 60's to protect missile outer covering from moisture, ice build up, rust and all. And it did a fair job. Real rocket science stuff! But early rocket science stuff! With use like in door knobs, locks, wd-40 will collect moisture. Which leads to collecting rust, dust, dirt, and in cold weather ice. It also solidifies...turns gummy. And looses what lubricating qualities it has...After a while...had. So the bearings will spin really fast now as the oil put into bearings is thin.. And later bearings will be ruined by you using the board as the oil breaks down. Have bearings cleaned by a pro or by yourself if mechanically inclined. Then buy a serious lubricating oil made for your skateboarding use. You spent good money for a good board. Do so now with the oil and enjoy!
