At work I came across some electrical contact cleaner. I needed to clean some contacts for a ice machine. I had never used this stuff before. I worked very well at removing corrosion that was on the old contact. And it dried fast and no residue.
…I thought to my self “I wonder if this will clean my bearing. I like a clean dry bearing. I have more at home. What the heck, why not?” I open my throw, sprayed it down, gave it a few spins and it was dry (this stuff drys really really fast) I put it all back together and gave it a toss.
I was Amazed. Smoother than i have ever felt it.
As soon as I got off work i went to lowes, bought a can of my own and cleaned every bearing i had in all my throws and got the same results with them all, mostly 10 balls but a few yyf spec. They all played far beyond my expectations. Tons of momentum made grinds glide and binds snappy, ss well as add a pretty fair amount stability.
I highly recommend this stuff to get your bearings super clean, super dry, super fast. No residue.
After using this, I feel like my yoyo skills have been dipped in butter.
