| Question | Answer |
|---|---|
| I just purchased one of your stainless filter holders and after only a few uses it is starting to rust. Is the unit defective? | Rusting of stainless steel holders can usually be attributed to high iron content in the water. Iron deposits create rust "stains" that can be removed with non abrasive cleaners or sometimes fine steel wool. All stainless steel can rust over time. It should be washed with DI water and dried thoroughly immediately after each use. |
