Lambert wrote the song with a songwriting collective known as the "Love Junkies," which is composed of
Hillary Lindsey,
Lori McKenna, and
Liz Rose. She described the writing process for the song as "fun" and that the hook was inspired by an idiom often used by her mom and grandma ("it will all come out in the wash") that she felt described getting "over the hump" after her last record which took her through a lot of personal trials and tribulations: "I think that it's got some sarcasm to it, but it's very honest. I haven't had a single out in a long time, and I'm just ready to have new music. I'm in a new phase of my life and ready to have new music out there that represents that," she explained. "This one just felt perfect as far as the vibe of it. It’s fun and lighthearted and I'm really excited about it." It was produced by
Jay Joyce, marking the first time Lambert has worked with the producer. "Locomotive", another song Lambert co-wrote with
Ashley Monroe and
K.S. Rhoads and first previewed on the
CMA Music Festival in June 2019, was also released alongside the single.{{cite web|url=https://pitchfork.com/news/miranda-lambert-shares-new-songs-it-all-comes-out-in-the-wash-and-locomotive-listen/|title=Miranda Lambert Shares New Songs "It All Comes Out in the Wash" and "Locomotive": Listen ==Critical reception==
