CLEAN FORMULATIONS AND USES THEREOF
Cleaning compositions and methods of using such compositions. The compositions comprise oxidizing agent(s); weak acid(s), and surfactant(s) (e.g., a combination of short-chain non-ionic surfactant(s) and long-chain non-ionic surfactant(s) or a combination of short-chain anionic surfactant(s) and long-chain anionic surfactant(s)). The compositions can be used to clean objects such as reusable water containers, home seltzer-maker bottles, hydration bladders, coffee mugs, etc.
