LOS ANGELES, CA (Catholic Online) - First of all, it's not necessary to have your car washed every week or every day. Some people view their vehicles as status symbols, and an extension of who they are. That isn't so - it should just take to one point to the other. Minimizing the time you scrub your car down with harsh chemicals puts less of these elements back into the environment, running down sewers and back into the oceans. 

Another helpful tip is to wash your car on the grass. This will give the grass a drink, and the soil will help break down impurities and prevent the water from entering storm water drains. Some of the chemicals in car wash detergents are nutrients for algae, so this water getting into waterways can help feed algal bloom and create other problems.

Be prudent with your use of the hose. Use an adjustable trigger nozzle to improve pressure while reducing water consumption.

As for the soaps and detergents you use, always use an earth friendly detergent. You could also just skip using soap altogether. If you do use detergent, don't use in excess of manufacturer's recommendations. You'll only waste money, put more chemicals into your lawn and you won't even more your car cleaner.

Another helpful hint is to use a bucket, and only use the hose for a final rinse. You can blast off grime with a hose going full blast, but that can waste an awful lot of water.

You should also wash in the shade, as hot metal evaporates water quickly. The more that evaporates, the more you'll need to use so try and either wash your car in the shade. Wait for a cloudy day or do it early in the morning or late in the evening.
