Thereof, what can I use to clean my bearings?

Clean all the old grease off thebearings,brake and spindle with solvent. Pop the old sealout with a pry baror even a screwdriver, then use solvent toclean upall the old grease. Dry with a rag or compressedair. Pack thebearings by mushing grease in between therollers untilthey're completely coated.

Secondly, can you use wd40 on bearings? It's important to use a silicone-basedlubricant.WD40 or others like it will dry outyourbearings and attract dust and dirt. It doesn'ttakemuch, and the excess will just spin out whenyoureplace your shields, pop your bearings back inyour wheelsand start shredding. Skate safe and enjoy yournew-foundspeed.”

Why must you never put oil on the brake blocks of a bicycle?

The oil reduces the friction between thebrakeblocks and the wheel so the brakes would notwork. Therain acts like a lubricant and reduces the frictionbetween thebrake blocks and the wheel.
