Lubrication is leaking out of wheels
I have a pair of inline skates that have been in storage for several years, never used. There's now a sticky substance coating the wheels, and the wheels won't turn easily. In addition, one of the wheels needs replacing, because a chunk of the wheel has broken off. Not sure if this was caused by the sticky stuff, or if it was damaged when I moved to my current place.
I'm wondering if the sticky stuff is lubricant that has leaked out, and if I could clean them up and add a new lubricant.
Do inline skates use a lubricant? And if so, what type, and how should it be applied?
