Restoring and caring for brass car lamps and horns
April 5th, 2010Something I hate to see are brass lamps that have been over polished. Over time continual polishing wears the brass away, especially on any edges, and gradually removes any lettering. This process cannot be reversed. Another problem with old brass starts in the manufacturing process which leaves stresses in the brass. Eventually small stress-relieving cracks start and the formation of these can be greatly accelerated by acid corrosion. Many brass cleaners contain mild acids so using them is likely to cause damage, like a wedge forcing the small cracks further apart. I have found ways of dealing these problems.
