About 4-5 months ago i purchased a brand new yoyo that had a satin finish on it, about a week after i got it i found these weird dots all over it, I thought it was tarnish so i polished it up with some compound and it seemed to help, but then it started coming back.
I got tired of polishing it every other day and sent it for a more professional polish, and low and behold it came back in no time flat.
I’m now noticing this on all my yoyos with exposed raw aluminum.
Could it be that the sweat that the yoyo collects is getting stuck to the foam?
If so how could I get rid of it and solve the problem?
