Use Appropriate Cleaning Products
When cleaning fire doors, choose appropriate cleaning products. It is recommended to use warm water and a low-foaming detergent, avoiding detergents containing corrosive or highly chemical ingredients. Alternatively, you can use a cleaner specifically designed for metal surfaces, but pay attention to the usage method and dosage.
Correct Cleaning Method
1. Before cleaning, use a cloth or vacuum cleaner to remove dust from the door surface to avoid scratching it.
2. Pour the cleaning solution into a basin of water, dampen a cleaning cloth, and gently wipe the door surface. Do not rub excessively. Also, be careful not to let water seep into the door seams.
3. After wiping, use a dry towel or paper towel to dry the water and residue on the door surface.
Other Precautions
1. During cleaning, protect door locks, handles, and other structural components from liquid corrosion.
2. If stubborn dirt remains after cleaning, it is recommended to use a professional door cleaning service.
