Big Wash

Big Wash is a self-serve car wash and truck wash in Katy, Texas.

Wash bays with a pressure wand and foam brush where you do the work yourself — pay with quarters, a card or your phone, depending on the site.

Wash bays and wash lines built for tractor-trailers, buses and RVs — tall doors, long bays and equipment for heavy vehicles.

It is open 24 hours a day, seven days a week.
