How to Keep Brass Door Knobs Shiny

What You'll Need
Brass Polish
Clean Cloth or Rag
Blue Painters Tape

Brass door knobs are shiny when they are newly installed. With use, the shine will eventually disappear due to grease, grime and other contaminants that can cause the metal to loose its shiny sheen. Brass is an alloy - a mixture of copper and zinc. This combination of metals creates a golden color that gives brass door knobs their stylish appearance. When exposed to moisture, the brass will naturally form a patina as a means of defense against corrosion. The oxidation process forms the patina and will also cause the brass to become dull in appearance. To keep brass door knobs shiny, read on for simple instructions.

Step 1 – Polishing with Brass Polish

Brass door knobs can be polished easily using commercial brass polish products. This chemical mixture easily removes the patina, grease, dirt and grime from the door knob’s surfaces. To use the polish, simply place a small amount on a rag and use it to wipe off the door knob. Simply rub the rag until a clean shiny surface is revealed. Afterwards, buff the door knob with a clean soft cloth.

Step 2 – Polishing with Ammonia

Another alternative to polishing brass door knobs is using ammonia. Ammonia strips off the patina as well other contaminants on the knob. To use ammonia, simply put a small amount on a clean rag and use it to wipe the surfaces clean. Buff the knob afterwards with clean cloth.

Step 3 – Polishing with Natural Products

Perhaps the safest way to keep the brass door knobs shiny is to use safe and natural products available in the kitchen. One way to make a natural polish is to mix equal parts of vinegar, salt and flour in a container to make a paste. Another option is to replace the vinegar with pure lemon juice extract.

To use the paste, apply it evenly on the door knob and allow it to sit for about ten minutes. To keep the paste from falling off, cover the knob with plastic a bag. Allow the paste to dry completely before removing it. Place newspapers on the floor under the knob when removing the paste to save on cleaning time. Use a clean rag or cloth to remove the paste and buff with a soft cloth afterwards.


In order to keep the brass doorknobs shiny, make sure to polish them at least every week. Make sure to keep an extra supply of ammonia, brass polish or natural polishing products for regular cleaning purposes.

In order to protect the other parts of the door from being stained with brass polish or ammonia, one recommendation is to wrap the surrounding areas with blue painter’s tape. This tape will not stick to the surfaces too much and will safely keep the other surfaces safe from the chemicals used in the polish.
