@kriswright What about canned air or using the vacuum cleaner then?
I suppose, in a worst case scenario, you could put your Amiibo tilted upside down under running water so that the base stays dry while the rest gets a good showering. I doubt the paint job will be damaged from a bit of water alone.
If I happen to end up with any for some reason then yes, I would display it. If they work like Skylanders where they can be used on the portal without removing them from the box, then I'll also keep them sealed inside the box.
Maybe. But, based upon the downgraded retail versions, probably not. They looked super slick initially, but many now look super cheap - as if bought out of a gumball machine or something (based upon retail un-packaging videos).
