Distilled water?

I would use 91% iso alcohol instead

Yeah, I can’t see the old Hasbro FAST 201 having a “High Quality” bearing or the duncan out of an old Throwmonkey for that matter! 201 bearings have 7 balls. The duncans have 9 balls. I’ve also had some duncans outer race rust(so not stainless Steel?), but have never had a 201 bearing rust making me assume they are stainless steel?.Other than that I have no idea what “Quality” these bearings are. I’ve never had it happen with ANY bearings other than the ones mentioned and I use bearings for a lot more than just yoyos. The ones that fell apart in mineral spirits really threw me off though.

Here’s a pic of the 201 bearing that fell apart in mineral spirits. I guarantee I could put it back together(as I did with the duncan that did the same), but I actually like it apart.

I can’t find anything visually wrong with any of the parts, and have had a pretty extreme close up view of it in it’s entirety. When I soaked in MS, it was in a small GLASS jam jar, and I did shake it lightly occasionally. The one blown out with compressed air had been cleaned in the same manner, albeit not the same week. The air was blowing on the side of the bearing retainer that is face down in the above photo.

Yup, that’s the crappy kind of cage. Those are the ones that tend to cause more problems for me.

but then you have to worry what the last 9% is, 100% alcohol or acetone is the way to go

100% acetone is the way to go, you just have to be responsible and careful.
