Corrosion of Yo-yos


#1

Has anyone noticed, specifically collectors, that anodized yo-yos you’ve had for a year or more develop a subtle corrosion of sorts… intermittent tiny black dots on the surface area of the yo-yo…

Is there any proven method for “polishing” yo-yos that will not in any way damage the yo-yo?

I’m a drummer and I feel like this is a similar question as what cymbal polish/ cleaning method should I use if I want to reduce the chances of removing the logos when cleaning cymbals…
