Carrie Underwood declares here to her cheating man:All those midnights sneaking in
I'm late again, oh, I'm so sorry
All the Ajax in the world ain't gonna clean your dirty laundry
The songwriters were especially pleased with their use of a word that doesn't normally crop up in country songs. Zach Crowell shared with Taste of Country
"When we came up with the Ajax line, we loved that line. 'Ajax' we knew was a buzz-y word to say, and a bizarre word to say," he explained. "No one else is really saying the word 'Ajax.' When I think of Ajax, I typically think of shower cleaner and tub cleaner, and we were like, 'Do they make clothes detergent?' So we Googled Ajax detergent, and we were all super-excited when we saw that they do make laundry."
"We were excited, 'cause we could use our word correctly," Crowell continued. "We knew that word was a buzz-y word, especially in the melody and the post-chorus part that it's in. We knew that would be a cool line, if we were lucky enough for someone to record it. Anytime you can find a word like that, find a buzz-y word that lyrically fits and melodically fits, you kind of get excited about it, because it's hard to do. Those words stand out."
