firstly i would like to point out that my palms are not above average on the sweaty scale, in fact i would probably say they are below average though unfortunately there is no way i can prove that. anyhoo, i have become increasingly aware that when i type for a long time on my pb there are marks being left behind by my palms on the keyboard rest. i try to rub off the marks with a tissue but this doesn't seem to get rid of it completely. i don't particularly want to wet the area as it is so near the keyboard and don't want to ignore the marks in case they contribute to discolouration of the rest (i think i've read somewhere that can happen). so can anyone recommend a product/wipe that will clean the area thoroughly so my palms can sweat in peace?
