Cotton towels for drying is the way to go. I've saved so many old worn out bath towels that I have a ready supply as each towel gets too wet to dry any more. As for wash mitts, I have one for the upper part of the car and a separate one for the lower dirtiest parts where the road splash ends up. For tires, I use a soft brush. Oh, and for after washing the dirty towels in the washer, I use 3 wool dryer balls to make them fluffy soft and to be sure any residual dirt is removed from the towels. Never use fabric sheets on car drying towels. They leave a residue that streaks.
