Caring for your Mezuzah

The mezuzah's outer case can be lightly dusted. Never use liquid cleaners because they may seep within the case and damage the parchment scroll. Every three or four years, the scroll should be removed and inspected by a trained sofer to ensure that it has not become faded or damaged in any way that would diminish its sanctity and cause it to lose its protective power.

When removing the old mezuzah cases, the nails, screws and tape previously used to affix the mezuzahs may be discarded. However, mezuzah cases and mezuzah wrappings should be treated as sacred material and require genizah, interment, after their use.
