How to Store Drano Products

Like with most other cleaners, it’s best to keep Drano products in a room temperature, dry location. A good space for this is normally under your bathroom or kitchen sink. Alternatively, you could store it high up in a utility closet, out of reach from wandering hands.

Final Thoughts

Although Drano doesn’t “technically” expire, its shelf life is still important to pay attention to. After around two years, your Drano may not work as effectively as before. That doesn’t necessarily make it a faulty product, but it does hinder it from working like it should.
