Brass fireplace screens create a beautiful addition to any home and generally can be easily cleaned. While several retail cleaning products are available, these are often expensive. Instead, a simply, homemade solution will clean and polish brass just as good as those found in the hardware store.
Lacquered brass is the easiest to clean, as it is already sealed and protected. To clean, simply wipe the fireplace screen with a damp cloth. For any build-up residue, add a few drops of liquid dish detergent to the rag and rub onto the brass surface. Wipe clean with a damp cloth, and the brass fireplace screen will look brand new again. Non-lacquered brass screens will require a bit more work, as noted below.
For non-lacquered brass screens, pour ketchup onto a cloth and rub into the surface. When clean, wipe off remaining residue with a damp cloth, then buff with a fine grain buffing pad (found in any hardware, home improvement or auto supply store). Repeat every one to two years to keep the fireplace screen looking its best.
Vinegar is a mild solution that cleans, disinfects and deodorises brass surfaces. In a spray bottle, mix a solution of one part water, one part distilled white vinegar (found in any grocery store). Spray the solution onto the brass screen and polish with a damp cloth. Let air dry, and your brass fireplace screen will be clean, polished and bacteria-free.
