Just cleaned up my Rift S after a few weeks of use. I mean I maintained it daily by using a fibrecloth to wipe the lenses after each use or while using because the lenses just get nasty, but damn do we as humans leave small bits of skin behind. Took the entire cover off and behind it were tiny white specs. Everything cleaned but damn when you wipe the lenses the follicles get pushed in the small area between the crevices of the lenses. I tried using air pressure and it got most out but damn I can already tell in a year this thing is going to look rough. The shitty fucking foam is awful on your skin. Feels like you're rubbing your face with sand paper after a while and with my sensitive skin it leaves some red marks every time. Soaks up sweat too, even if you're as careful as me. 

That all said about how nasty it is do you guys have any suggestions for extra covers to buy in advance from amazon.co.uk? Something that is a package would be nice and no more than 30-50 area. Mainly what I'd like to know is if you guys have experience on the different covers: Cloth vs silicone for example, over long periods of use. Also grips would be nice if they were in the package so that these battery covers don't fly off in beat saber.
