Here are some of my favorite car care products. They are both easy to use and provide outstanding protection for new car materials. If your smart isn't already attracting enough attention, using these products will keep it looking new for many years.
Note - I do not work for or make money from any of the following companies

Washing
You want to avoid fine scratches and swirl marks as much as possible. I use a
Grit Guard at the bottom of my wash/rinse bucket as well a real
Wool Mitt. The mitt is high quality and has lasted 3+ years.
Add your favorite car wash liquid to the bucket and fill it with water. Three that I like are
Zaino Z-7, it is very mild, with medium suds.
Ultima Paint Guard Wash, also mild and a bit less astringent than Z-7.
Gold Class Car Wash Shampoo & Conditioner, not as strong a cleaning action as the others but can't be beat for the low cost and easy availability.
After using a hose to rinse the car with water, soak the wool mitt and lightly rub off the car from the top down. The cleaning liquid will do most of the work so the process is easy. Do not use the mitt on areas with heavy road grime like tires. For these areas use a micro-fiber cloth. I buy the yellow ones at Costco.
Rinse with a hose and you're ready to dry.
Note - For the first wash of a new car I use Dawn dishwashing liquid instead of the liquids listed above. This removes any low quality silicone based coatings added by the dealer during preparation. This is only required for the very first wash.
Drying
Using the correct micro-fiber towel makes drying very easy, and helps prevent fine swirl marks. The
Sonus Der Wunder Drying Towel is excellent and lasts a long time. I've been using the same four towels for 5 years.
