Miranda Lambert wrote "Wash" with the Love Junkies: Lori McKenna
, Liz Rose, and Hillary Lindsey. The songwriting trio were also responsible for Little Big Town's huge hit "Girl Crush
," and Carrie Underwood's "Cry Pretty
" (with Underwood).
Lambert explained that she and the Love Junkies like "to talk about girly things and things going on in life" during their co-writes. She added: "This song is just kind of a mix of scenarios that all of us have either been a part of or seen, or, you know, something that's happened in all of our lives."
