If you're washing your car at home, you could be wasting a lot of water. The average home car wash uses about 80 to 140 gallons of water. This water picks up all the pollutants off your car, such as fuel, gas, oil, and tar and mixes it with the soapy car wash ingredients. This soapy, oily mixture then flows from your yard, to the storm drain, and ultimately to streams and lakes where it damages the environment and causes harm to marine animals. So how can we keep our car in top shape while still protecting the Earth and its fellow inhabitants? Here are some eco-friendly tips for washing your car at home.
Do Away with the Open Hose
Many people prefer washing their car at home, but to reduce the amount of water you use, try an automatic shutoff nozzle for your hose. This nozzle prevents the continuous flow of water and can save up to 70 gallons of water per wash. You can also use a power washer, which uses about 2-5 gallons of water per minute, compared to an open hose which uses 10 gallons per minute. Simply using a bucket is also a great way to manage how much water you use. Fill your buckets with water and refill only when necessary. This will allow you to calculate exactly how much water you’re using and force you to cut down.
Watch Where You Wash Your Car
Most people wash their car in their driveway, but this water goes directly to the storm drains. These typically don’t lead to sewage treatment plants but instead go directly into our lakes and streams. An eco-friendly approach to car cleaning is to move your vehicle to a grass or gravel surface. This allows the ground to soak some of the water and filter out the harmful contaminants that make their way into runoff water.
Use the Right Products
Many soaps that we use to wash our cars have chemicals that are harmful to the environment. These chemicals decrease water quality and damage the life of aquatic species. Instead, opt for a waterless cleaner. You can get a spray-on product and wash your car with minimal or no water at all. These solutions are also biodegradable so they don’t add any chemicals or pollutants to the environment. Simply spray on your car and use a microfiber towel to remove dirt.
Following these three tips will help reduce the amount of water you use when washing your car, and ultimately protect the aquatic environment from harmful pollutants.
