superchargerA company already known for its environmentally friendly bent could soon offer another service to entice drivers who are mindful of their effect on the planet. Tesla might soon start a car wash program at its charging stations across the country. The electric car company is currently testing a pilot program in California, according to Left Lane News.

It’s a neat idea, but it sounds like you’re going to have to pay top notch dollars for the eco-friendly service. Should Tesla pair with Eco Green Auto Clean, drivers will have to pay upwards of $40 for a wash. That’s because the Eco Green Auto Clean service uses just one cup of water.

Tesla customers would be asked to sign up for a car wash program. Drivers of the smaller Model S would pay $80 a month for two monthly washes. Drivers of the larger Model X would be charged $90 a month, given that it’s a crossover vehicle. Elektrek reports that the program is being tested at a supercharger station in Freemont, California but that Tesla spokespersons have declined to provide more details.

Eco Green Auto Clean already offers similar services to companies such as Google, Elektrek reports.

Eco Green Auto Clean uses microfiber towels, a biodegradable auto wash spray and about a cup of water per vehicle. The company claims that the process is environmentally friendly and ‘designed to lift and dissolve dirt on contact.’

We’ll keep an eye on this one and be sure to let you know when a car wash option could be coming to the more than 620 Supercharger stations across the country.
