When you're using these massively expensive swabs to clean your sensor you can only use them once. Or can you? On the sensor, yes only once otherwise you just end up putting more microdust on the glass. However, you can give it a flick, wet it again and use it to clean your dslr mirror and underside of your focusing screen because you don't even see micro dust on them. The big stuff however will fall on your sensor sooner or later. I then wet again but this time just the corners to clean the eye piece. After that you can use it even more to clean all the little grooves on your camera and lenses. Get your moneys worth.
