I did my first polish yesterday and used 1 orange pad and 2 white pads. Everything seemd to go very well. I cleaned to pads last night with the Snappy pad cleaner in my sink. The orange pad I used the SIP on and the white pad I used some Zaino PC on both came perfectly clean and returned to their new color. The white pad I used the grey Nano Polish on turned orange in the center? Does anyone have any ides?
