I found 2 different ways of removing wax from brass:
1. Wash in hot, soapy water. You can find this information at this site:
"..To polish antique brass pieces: wash in hot, soapy water to remove grime,
wax, etc. Rinse and dry. Moisten a soft cloth with boiled linseed oil and rub
on the brass surface until all the dirt and grease have been removed.....Very
old brass items, especially if in poor condition, require special care. Consult
museum experts for advice.."
I checked a museum site (Henry Ford Museum) to see what they recommend for
cleaning brass. They did not really address the issue that you are concerned
with but it was very informative generally. You can read that article at:
2. Another method that was interesting was 'Blow drying'. Its mentioned at this
Here's an excerpt from that discussion:
"..First, is the brass laquered? Removing candlewax with a knife often
removes the laquer. Using a brass cleaner on top of the laquer damages
the finish, too. You can't polish through the most likely damaged
laquer coating...and need to remove it.
In my opinion the best method is to heat the wax with a hair blow dryer and
wipe it off with a trash rag or paper towels as it melts. My husband has a
modified hair dryer that is much hotter than usual because he uses it for
Blow drying at high heat might actually work! I hope this helps.
