In our continuing Green Your Summer series, we’re taking a look at how to save water, time and cash by washing that car or bike without turning on a tap or lugging around a heavy hose.

It’s estimated that washing a car at home can require up to 150 gallons of water — a wasteful use of valuable water.  And the dirty runoff water created from conventional detergents winds up downstream polluting our rivers, lakes and oceans.

Eliminating almost all toxic nasties in its formulation, here’s a brand that derives its power to clean and shine by utilizing eco-friendly, plant-based ingredients.

Lucky Earth was founded by parents whose 2-year-old daughter suffered from Multiple Chemical Sensitivity Disorder.

Water-based, these products are packed with coconut-based surfactants to help whisk away grime. They also include a tiny bit (less than .05%) of the preservative, Benzisothiazolinone.

In addition to the car’s exterior, the Car Wash Spray can be used on the dashboard, leather seats, doors and any other non-fabric surfaces; 32 oz Spray Bottle, ($14.99).

The Waterless Bike Wash is the exact same solution, packaged in a smaller dose for bikes, scooters and motorcycles; (16 oz, $7.99).  Or try the handy Starter Kit (with 4 microfiber towels and the Tire Wash Spray).  As a socially responsible company, you can also feel good knowing that Lucky Earth donates 1% of its net profits to California-based Heal the Bay.
