Preparing Cleaning Tools
To clean a fire door effectively, you first need to prepare the appropriate cleaning tools. Commonly used tools include a soft-bristled brush, bucket, laundry detergent, rubber gloves, and sponge.

Cleaning Steps
1. Clean the door frame: Use a soft-bristled brush to remove dust and debris from the fire door frame. Then rinse the frame and door surface with clean water. Finally, dry the frame and door surface with a clean cloth.
2. Clean the door surface: Use a sponge to wash away stains and dust from the door surface. The sponge should be damp, but not too wet. If there are oil stains or other dirt, you can use a foam made of laundry detergent or soapy water to clean it, then wipe it with a damp sponge.
3. Clean the door gaps: Use a brush or other tools to clean debris and dust from the door gaps, ensuring they are clean and odorless.
4. Wipe the door handle: Use a sponge or cloth dampened with cleaning agent to wipe the door handle and related metal parts, ensuring there are no oil stains, fingerprints, etc.
Fire Door Routine Maintenance
1. Regular Cleaning: Fire doors require regular cleaning, such as monthly or quarterly.
2. Moisture and Corrosion Prevention: Fire doors are susceptible to moisture and corrosion. To be on the safe side, avoid hanging wet clothes or other moisture-prone items on fire doors.
3. Avoid Acidic Cleaning Agents: Acidic cleaning agents should be avoided when cleaning fire doors, as they will affect the fire resistance performance of the doors.
