It's turning into springtime and with that comes tons of pollen.  If your car is parked outside, chances are that at some point it's going to be covered in yellow dust.  Because of that, many people's first reaction is to wash their car, however you can waste a lot of water if you're not careful.  Instead, read these tips below to help the environment even when cleaning your car.

• If possible, wash your car on any subject other than pavement.  Grass, gravel, and other natural grounds have enzymes which help break down and use the runoff water instead of simply sending it down the drain.
• If you're simply washing your car, doing it from home is fine.  Use your own biodegradeable soaps and limit the amount of water used.  If you want to do more detailing or hot wax, take it to an eco-friendly carwash.  They recycle their water and have environmentally concious options.
• Look into waterless options.  Select stores do sell waterless car wash options so you can preserve water when you get the pollen off your vehicle.
