I use this thing called "Magicloth"
I bought at our Post Exchange. It's basically a Chamois, but it still works really well. We bought it at a bargain price of $20 per package, and I'd say it's worth it. You can take it and cut it in half; one for washing and one for drying. It's been working for be on both washing and drying my Focus.
I also use Turtle Wax brand car wash and wax.
