i’d like to tell you about the most important night of my life … so far. your wife was right ,glad you listened to her and did not give up . he wants them to take another look. using a metal cleaner will remove the patina and change the look of the piece and may cause damage to the brass, copper, silver or gold. i have visited friends without needing to check and double-check my calendar for fear that i’d be too tired or in too much pain to have fun. we could not have had a better experience!
