Building the mouse Logitech won't make

My biggest issue with the MX Ergo is the finish on the "top" part. After a while it starts to degrade and becomes sticky. I have not found a way to clean it properly. :/

I cannot say anything about the MX Ergo. So far, my MX Vertical hasn't gone all sticky on me (yet?).

What worked for me on other sticky plastics was rubbing alcohol. I does leave the finish slightly different than it was initially (less grippy), but I've had good results.

I'm going to give it a try. Thanks for the suggestion!
