Hey  
When searching through a local hardware store I came across this:  
[http://www.actioncan.com/type/463/AC-90-Multipurpose-Lubricant-Industrial-Spray](http://www.actioncan.com/type/463/AC-90-Multipurpose-Lubricant-Industrial-Spray)  
Would it be a cleaning solvent or lubricant?  
I have my suspicions that it may leave residue like WD40 on the bearing and have not bought/used it yet.

From what it says that it does no. I don’t think an “anti rust film” is a good thing for your bearings. Maybe to protect raw yoyos?

It would however protect you bearings from rust.

Might be responsive for a while but I don’t see why it wouldn’t work. As for WD-40, it DOES NOT leave a residue. WD-40 can be broken in just like any other lube. What makes people think WD-40 should not be used on bearings is because dust is attracted to WD-40, as long as you keep the shields on your bearing, it should be fine and last you a very long time.

Wd-40 still sucks as a lubricant.

Why? Just because it takes a while to break in?
