In this heartfelt track, Ryan Adams delves into the emotional journey of overcoming a deep-seated relationship and the struggles of addiction. The imagery of rain washing away all traces of his past lover symbolizes a cleansing, purifying process, allowing him to breathe and start anew. The recurring theme of water throughout the song not only represents turmoil but also rebirth. Adams acknowledges the difficulty in staying clean both emotionally and possibly from substances, reflecting on how sobriety doesn't erase memories but empowers one not to relapse. Ultimately, "Clean" is about finding liberation and peace within oneself after enduring hardship.
