too much friction after 2 weeks

I had always issue, even one time my hand sweat and there are created spots on bottom of mouse and it has terrible friction. I can tell even, after one use !!! After 2 weeks mouse is useless... And i follow all maintenace rules:
1. don't touch it with dirty hands
2. cover that at night
3. clean it with microfiber cloth
4. don't use water

It doesn't matter, there is insane friction. I am better on garbage office mouse for 3$...

I heard about polishing, while it helps a bit, i am not skilled with my hands, i doubt i will be able to apply same pressure all time. Also i even asked on chemical forums and didn't advice anything. Biggest problem is spots are created from sweat, which cause huge friction, i tried isopropyl alcohol everything nothing worked...

Edit:

Mice skates are of low grade quaility !!! One time my hand sweat and on bottom of mouse on the skates are created spots from sweat and there is too much friction already after 2 weeks !!
