I’ve got some pretty nice yoyo’s, but i’ve never really thought about ways to maintain them. Should I clean my yoyo’s? How? Am I supposed to use lube or something for the bearings? Any tips about keeping my yoyo’s in best condition and spinning well would be great! Thanks!
Cleaning - If they get dirty, take out the bearing, clean them w/soap and water. Dry well. Reassemble.
Lube the bearings - Yes, lightly. Opinions on this vary widely.

Change the string - As needed, before it breaks.
When should I change my string… heh?
