Try a soft tooth brush,or a paint brush. Try using a quick spray detail spray by Eagle one or Meguires, something to remove the wax and yet not take off the shine. Best thing when waxing your car .use Eagle One Polish/Wax, use the Quick detail spray on the sponge they give rather then water. That way you DEMAGNETIZE the wax as you put it on and it wont attract the polen or dust as fast.
