It's a Wash is where Greg lives in his van, as it is almost always seen there. How and when he acquired it has not yet been revealed, although it seems to have replaced his occupation as a rock star after some time. His inspiration to find a job was revealed in "Greg the Babysitter", but he would have had to take ownership at a later date.
The exterior of the car wash houses a logo with an elephant presumably dousing itself with water and the business name. It has two main sections with the car wash being in an 'L' shape and what seems to be an office space being allocated adjoining to the wash. The interior of the car wash has only been seen in "Cat Fingers" but the office space has yet to be revealed.
It is seen again when Steven is taking a full cat form. They decide to rinse the cats off using the superwash.
The car wash makes an appearance as Steven is going to look for his father to rehearse for Beach-A-Palooza.

Steven undoes this new timeline, causing the boat to get stuck and cause the initial damage.

- Within the context of business, "a wash" is a business decision which isn't profitable enough to count as a success but isn't costly enough to count as a failure (i.e. breaking even). This possibly references Greg never being seen having much business and not living particularly well himself, but still seemingly earning enough to support Steven.
- It is located at the corner of Waterman and Thayer.
- According to "Steven Universe: Art & Origins", It's a Wash was going to be originally a laundry store called "It's a Fold".
