If you’re a proper skate nerd then you’ll probably strip, clean, lube and re-assemble your bearings. Go Project Bearing Milk* was designed for the lazier skater, with a view to giving you some extra zoom WITHOUT spending your Sunday dismantling your bearings. Just give your bearings a wipe down (kitchen roll will do), then add three drops and work them into the bearing by spinning it a little. The lube will give you some extra spin-time and aid any expulsion of grit, dirt and dust whilst you save up your pennies for a new set.
*It's not actually Milk, it's ultra light Oil. (Oil works better than Milk. Milk sounds cooler than Oil)
