Things You'll Need
1/4 cup dishwashing detergent
1/2 cup baking soda
Brass cleaner (optional)
When cleaning a security door, it is best to just clean one side at a time because people will still be coming in and out of the door, so you don’t want both sides soapy at the same time. If the door handles are brass, use a brass cleaner rather than the window cleaner.
Clean the door during a time when traffic is slow to avoid injury to you or people going in and out of the door.
Most security doors are installed in businesses, factories, schools, hospitals, military bases and other types of buildings where safety and security is important. The heavy security doors are usually made from steel and are quite thick when compared to a traditional door. With so many people passing in and out of security doors daily, the doors can become dirty and soiled from filthy hands, clothing, packages, shoes and other items that come into contact with the doors. You can clean a security door as you would any steel or metal door without removing it.
Mix 1/4 cup dishwashing detergent with water in a 1-gallon bucket.
Dip a sponge in the cleaning solution and wipe down the entire security door. Go over the door two or three times with the sponge to remove the surface dirt, fingerprints and marks.
Empty the cleaning solution from the bucket and rinse the bucket with hot water.
Prepare a new cleaning solution consisting of 1/2 cup baking soda with water in a 1-gallon bucket.
Use steel wool to clean the door with the new cleaning solution. Scrub hard around black marks and other grime on the door. You may need to clean the door more than once to remove all marks.
Empty the cleaning mixture from the bucket and rinse the bucket with hot water.
Clean the door handle with Windex or any brand of window cleaner and a paper towel. Spray the cleaner on the handle and wipe clean with the paper towel.
Repeat these steps to clean the other side of the door.
