How Many Gallons of Water to Wash a Car


You may not realize it, but you use a lot of water when you wash your car. The average washing machine holds about 27 gallons, and most people use about 30 gallons per load. That means that if you’re washing your car once a week, you’re using more than 1,000 gallons of water just to clean it!

Now, let’s say that you want to conserve water and only wash your car every other week. You’d still be using 500 gallons of water each month just to keep your car clean. And that’s not even including the water you use for other things like rinsing the soap off or watering your lawn!

When it comes to washing your car, how much water you use can be just as important as what kind of soap you use. If you use too much water, you’re wasting resources and money. But if you don’t use enough, your car won’t get clean.

So, how many gallons of water should you use to wash your car? The answer may surprise you – only 3-5 gallons! That’s right, even a large SUV can be washed with just a few gallons of water.

Of course, this number will vary depending on the size and condition of your car. A smaller car or one that’s particularly dirty may need closer to 5 gallons. To save even more water, try washing your car on the grass instead of the driveway.

This way, the water will seep into the ground instead of running off into storm drains and eventually making its way into our waterways.
