"It All Comes Out in the Wash" is a song co-written and recorded by American country music artist Miranda Lambert. It was released on July 18, 2019, as the lead-off single from Lambert's seventh studio album Wildcard. The album was released on November 1, 2019.
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.
