I have waxed my new dooper for the first time and gave it a nice clean treatment. It's the first time i have waxed a car in my life

I used Eagle One's Nanowax and in the box was a pad for application and microfiber cloth.
I put all cloths that I have used in a washing machine but how should I clean pad for application?? I squeezed excess wax form it and do I need to do anything else? A detergent??
