As the title says I need help for choosing a product for cleaning the bearing.
I have the choice between acetone, lighter fluid and paint thinner
If anybody could tell me which is better, and your experience with any one of them would be great 
No to the acetone. Get Mineral Spirits paint thinner, not just any old paint thinner. Some others contain water and other things. Lighter fluid works too, just not as well. Make sure that if you go with the lighter fluid that it’s actually that and not butane. BE VERY CAREFUL! IF YOU’RE YOUNG, GET AN ADULT TO HELP YOU!
mineral spirits is the way to go. it just works way better than other cleaning fluids
