That's interesting to hear. You must be describing your experiences with those thin, square, yellow microfiber pads, several of which I received when I bought my most recent steam vapor machine. I'll have to try using them in place of the more customary round white terrycloth pads and see if I notice the same result as you. One source of microfiber bonnets is www.swedeclean.com. They are round and 19" in diameter.
