Meguiar's Ultimate Quik Detailerhttp://www.amazon.com/gp/product/B000RXNLK6/ (I use it for basically everything outside the car to touch up. I even clean the inside of the rims and exhaust tips with it)
Eurow Microfiber Towels 16in x 16in 36-Packhttp://www.amazon.com/gp/product/B0031B4YU2/ (some cheap microfibers and they hold up pretty well. I like the fact that they're yellow so you know when you should throw one out.)
