A car wash never felt so dirty.

A business in Malaysia reportedly offered car wash customers free sex after their ninth wash, according to the Malay Mall.

The alleged reward-program-to-end-all-reward-programs was born out of a partnership between the car wash and a massage parlor, police said.

After becoming suspicious that the massage parlor was harboring illicit activity, authorities raided the business and found that several of its patrons had customer cards for the car wash.

The cards offered a little more than your average discount, though.

"To get the extra 'offer,' customers must send their cars for washing nine times within a certain period," Officer Emmi Shah Fadhil said. "The tenth car wash will entitle them to free sex."

Nine Vietnamese women believed to be prostitutes were arrested.

The Toronto Sun reports that four men suspected of running the sex ring were also arrested.

The Stir's Nicole Fabian-Weber fears the sex-for-car-wash deal undervalues one of life's great pleasures.

"Call me old fashioned, but I think intercourse is worth a scosh more than nine car washes," Fabian-Weber writes. "... I'm all about the punch card. But, I don't know, I have to say, after reading this, the term 'customer loyalty' has been sullied for me a bit."

    This was one of the workers at Drom in NYC. He wasn't supposed to perform, but when a competitor spilled a beer on stage, Mop Guy gave a little show. Awesome.
