Can I store OxiClean in a sealed container once I have diluted it with water?
NO. OxiClean solution cleans with the power of oxygen, which is released as it works. After mixing, always keep the mixed OxiClean solution in an open container or a container that has a small opening in it (like the OxiClean mixing bottle). Sealed containers will leak or expand, sometimes causing the container to burst. Discard extra solution in drain or toilet after use. OxiClean powder (unmixed crystals) should be kept sealed and in a dry location.
