Problem with yoyo bearings

Hi please I need some advice, I have a problem with my bearings. The bearings stop working and become coming to my hand(only when i tug strong and pull hight)

about 10 mim of yoyoing from everyone. I in the lighter fluid and put a very small drop of oil in them (a tiny drop on the end of a pin) and then I twist them properly with tweezers. I tried yoyoing longer with that, but it doesn’t help. I needed some advice. Otherwise use OTS Fat yellow strings. And the original bearings from W1ld yoyos or the original bearings from yoyos from providers like Empathy or Offset. I also have the bearings without the shields that I gave away. Could someone please help me with this?

And I also have a problem with some bearings, that when I turn them very hard, they stop turning, but when I turn them weakly, they turn. Can anyone help me with this too?

as long as it’s deshielded, try washing it out with dish soap and water and a small brush like a toothbrush or similar. just make sure you dry it immediately and thoroughly. i use an electronics duster to blow dry mine out. the amount of lube you use after it’s clean is less important than the cleaning process. i flood mine with 8 or 10 fat drops of lube so don’t be afraid of the lube part, just make sure it’s good and clean
