Dark magic 2 problems

HI im a intermediate player and i had my dm for about 2 months. I havent done anything to the yoyo no bearing cleaning nothing even standard yyj speed bearing in it. Anyway recently i have been playing with it and it hasnt been sleeping as long. B4 it used to sleeep at least a minute and at most 1min and 30 seconds. Now it only sleeps barely to 30 seconds what happened. Do i have to clean the bearing. And if i do how do i clean the bearing???

clean it. get some mineral spirits


Best solution ever (seriously): Clean the bearing.

And the guide from Samad is one of the best. (As linked above)
