How to Clean Bronze Markers
The most common type of bronze markers that most of us are likely to come into contact with are those used for headstones. Over time these markers can become corroded and turn a dull greenish color. One of the first reactions to seeing a green bronze marker is to want to clean it and restore it to its original shine. This is a mistake and probably can't (and shouldn't) be done in any event. The slightly green patina that forms on a bronze marker is not a sign of deterioration, but a natural coating that actually helps to protect the bronze. However, over time bronze markers can become dirty and stained and need a certain amount of care. This is one case in which less actually is more.

Mix non-ionic detergent with distilled water as per the manufacturer's instructions and spray on your marker. Allow it to soak into the dirt and grime for 10 minutes and then scrub with your soft brush and use your skewers to remove the last traces of surface dirt. Spray with clean distilled water and blot dry with a soft cotton cloth. Do not touch the marker with your fingers after cleaning, as the oils on your hands will react with the bronze.

Tips & Warnings
Do not expect your marker to look bright and shinny after cleaning. Remember, the somewhat green patina is actually good for your marker.
In humid areas, markers may need to be cleaned up to twice a year; in dry areas markers may need to be cleaned only every two or three years.
In areas of high winds and dust, markers may need to be cleaned and protected with Armor-All up to twice a year.
Do not use shaving cream or other household cleaners to restore a bronze marker, as these can react with the bronze to form acids which are detrimental to the metal.
