Beauty secerts

This is not a mechinal issue but I know that a lot of you guys show your cars. What is a good soap to use while washing your car to eliminate water spots. It's starting to get a little warmer where I live and a few months ago, I bought an 02 black LSE Sport. Washing this thing is makes it shine like new but before I can get it all washed and dryed off with a microfiber towel, it spots like crazy. Now I know a lot of you have a black LS and was just wondering your secerts. Thanks in advance.

Softened or deionized water is the secret.

Failing that, wash in the early morning or late evening to help slow evaporation.

You could also try one of those in-line water filters for your your rinse water.

A bar needs to be used with a lubricant. Don't try to rub it dry.
