mouse feet poor durability + your mouse are to small

I talked about this with razer support and than told me to not clean mousepad with water, because it will damage threads in mousepad. Only thing they adviced me to clean mouse with with microfiber cloth for glass.
Which i do, i clean my mouse feed and mousepad with microfiber cloth, after each gaming session. Still during gaming, my hands sweat and than appear on mousefeet spots and mouse stick to mousepad. I even cover it during night so dust wont get on my mousepad. Aren't there any better material than teflon ? Teflon is already so old. I don't have money to buy mouse every week or so. Also what people with big hands, i have 19 hand lenght and width 12. My ring finger overeaching and i can't hold mouse in spots, which is meant to, i have death adder and even this big mouse i hold it only with finger tips. I would like to use 67g mouse if i had small hands. Why aren't there mice over 140 mm and 80 + for width. People with large hands are f2cked. And you can't play on 120g and biggest mouse have usually laser, still i tried most width mouse i found and it still was to slim for me. And air conditioner or fan doesn't help, it only takes longer, to sweat destroy mouse and mousepad.
