Splash Car Wash was founded by Mark Curtis and Chris Fisher with the opening of their first hand wash -- Splash, Greenwich. Both lifelong Greenwich, CT residents Curtis and Fisher cast aside their business suits and ties to immerse themselves in suds and water with the purchase of Greenwich Car Wash in 1981. Eventually renamed Splash Car Wash in 1994, to mark a totally innovative concept developed by Curtis and Fisher for washing cars on conveyor by hand in a tunnel, overwhelming response to their new hand wash became the catalyst for phenomenal growth at Splash.

Happy birthday FREE wash!

Love SPLASH - it’s my neighborhood go to! And how awesome to get a birthday bonus. The Staff is friendly - accommodating and always willing to go the extra mile. Only bummer is I have a white car and there are always those hard to remove spots like the tar residue. I hate having to ask the team to go get the special spray and give it another go - inevitably that’s always the drill.

Amazing Service

I have been coming to this car wash for 4 months now and every time I come the staff is so pleasant, they do an amazing job with both of my cars and always have special offers.

Great Car Wash Great Service

Darien Splash is top notch. Friendly staff and attention to detail results in a great car wash experience. I’ll never go back to the automated car wash that scratches your paint. Five Star experience!
