Watch where and how you wash your car. The soaps used for washing cars are very destructive to the environment (often contaminating your drinking water!), so start by washing your car less often and washing your car yourself. When you do wash your car, use environmentally friendly products.
At a minimum, move your car onto grass in order to wash it. This will help keep the chemicals out of your drinking water.
Try to go waterless and simply clean your car with a green window or all-purpose cleaner.
Let us enjoy the modern day available facilities but at the same time be environmental friends.
Let us respect the nature. Doing so, we shall save our future generations.
