Here's a quick way to clean - I actually get them in warm water to soften up the polish and brush the face - works fine by me.
I get more Blue pads than others, therefore don't need many spares of the other colours pads.
As mentioned a pad looked after can last a year and more.
Why would you need to blow air after each pass.
My pads always staying moist, key is as mentioned do not over do it with the S20 or any polish.
The 3 or 4 drops is all you need.
