human sweat damages PTFE surface, is it possible to clean it somehow ?
empleat:
I always had problem, each mouse i buy, already after 2 weeks has too much friction. I notice spots already after first use on bottom of mouse feet, which are from PTFE. I read liquid sodium used for PTFE surface etching, increases surface's adhesion. I though about using gloves, but i have large hands and they are hard to get by.
How does sodium, or other elements, which are contained in human sweat react with PTFE ? Does sweat damage PTFE permanently, because it seems so. I tried pretty much everything: cleaning with microfiber cloth, or using even water, isopropyl alcohol etc. But nothing worked ! These spots stay there and i cannot get rid of them. And friction permanently increased. I am not chemist, you would have to be professional with lab to figure out how to remove these spots, if it is even possible in this time, because who knows what is happening there on molecular, or atomic level... Mouse skates aren't cheap and these installed by hand, aren't as good as original and i have same problem with mousepads.

Welcome, Empleat!
I doubt that sweat deteriorates Ptfe. Salt in sweat contains Na+ ions, which are not liquid Na. All compatibility tables tell that Ptfe resists table salt, including brine.
Maybe your mouse feet are not of Ptfe. Pp or Pa would be a natural choice for me, gliding well, and much more durable than Ptfe that abrades quickly.
My mouse too rubs more strongly after few weeks, but it's a matter of dirt. I've suppressed any mouse pad and use the mouse on the desk surface since I have an optical mouse. Every few weeks, I clean the mouse feet and the desk area with any dry cloth, and the mouse glides again.

Thing is i cover mouse at night and never touch it with dirty hands and clean it with microfiber cloth.
So explain to me, how come after my hands sweating, there are created weird spots on bottom of mouse skates, which weren't there previously ? That has to have some reason - that it exists ! If not sweat that what ? It wasn't there when mouse was new. There is more things in human sweat, couldn't it be something else ? And is there some substance, that would clear these spots ?
I wish i could choose pp, pa. But never heard about mouse skates like that. I heard ceramic mouse skates have less friction, but they don't exactly fit on places, where default skates were, so there may be problem with stability etc. Also it may be too slick on polymersurfaces. Maybe i am gonna try them, but it would be nice to have something to reduce friction !!!
What about silicone spray on ptfe mouse skates and polymer, aluminium, glass, or cloth. Wouldn't it damage these surfaces ? There was one product to increase slickness between surfaces from steelseries, but it doesn't sell anymore. I don't know what i should use, so i don't make it even worse. I think i tried wd-45 once on worn out mouse and it didn't help, made things worse.
This really frustrated me long time, because there is not much i can do. Any ideas would be helpful thanks ! And i don't have money to buy everything new every 2 weeks !
Do you think polisher would help ?: https://youtu.be/PQrt1PEM1Qo?t=218
I would try anything at this point !
Corribus:
Even clean skin has oils and other substances on it that can contact transfer to other surfaces. Also soap leaves residues that you don't see, and so does hard water. Easily these oils and other substance could create enough residue to roughen a polymer surface, and cleaning without abrasion and chemicals probably is not effective.
There's that. Plus polymers themselves do age. They do this chiefly by UV light and oxidation in air (particularly polypropylene). These processes do not happen quickly in most cases, but kinetics could be affected by aforementioned substances, which can permeate into plastics and change their mechanical properties, sensitize oxidation, and so forth. Fresh polymer will also outgas or otherwise leach various residual solvents and additives used during manufacture, and this can contribute to polymer aging as well. This may also be chiefly observed during the first week or so after opening the product and using it for the first time.
I don't have a sense of how much of a change in friction you are experiencing. I get the feeling these are only minute changes that are important to you but probably most consumers would not even notice. So if the changes are indeed very small, some of the above mentioned factors could easily account for it.

I bet for dirt on the mousepad being picked by the mouse feet.
The increase of friction is quite noticeable to me too. My answer was to remove the mousepad and clean regularly this desk area.
