I'm 99% sure it removes exhaust. It's intended to remove all debuffs, so yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, otherwise it's either not actually a debuff (like karthus's ult, which gives a debuff icon but is not in fact a debuff) or it's a bug. You can generally assume that if it gives a persistent effect of any kind, it can be removed by quicksilver sash. However, consider the cooldown, and realize just how rarely removing lux's passive and marks of the storm (if you really need to, you can just remove the stun itself) is a better idea than saving it for something like a malzahar ult.
