On Feb. 22, starting at noon EST, Florida and Michigan residents can drive away dirt and receive drive-in dessert at the same time, according to a company press release.

The first 200 customers at each El Car Wash location will receive a free Crumbl dessert with their wash. In addition to the free dessert, these customers will also receive an exclusive Crumbl /El Car Wash co-branded air freshener.

This promotion is for one day only, so customers are encouraged not to delay their trip to El Car Wash.

El Car Wash has 65 locations in total, with 63 in Florida and two in Michigan. These locations span across Florida but are especially concentrated in the regions around Miami, Broward, Palm Beach and Orlando.

Crumbl has 77 locations across Florida and 23 across Michigan. Known for its viral weekly rotating menu of delicious desserts, Crumbl is among the fastest-growing dessert chains in the world. Selections from the Feb. 17-22 Crumbl menu will be offered free to the first 200 customers at El Car Wash locations on Feb. 22.

"Our goal is to deepen our brand affinity through unique collaborations and superior service," said Justin Landau, co-founder and chief strategy officer at El Car Wash, in a conversation with traded.co.

The Crumbl/El Car Wash air freshener features El Car Wash branding on one side and Crumbl branding on the other. The air fresheners are cookie scented and will only be available on Feb. 22 while supplies last.
