Now, here's another vids for you and others to view and enjoy, a resto on one of the Brilliant Finish Cymbals.
I'd likely believe that for these types, Bar Keepers Friend will work, but might not be the optimal or even the correct product to use. In essence, there might not be a "one works for all" situation.
Restoration-cleaning of a finish, whether paint, a wrap, or a metal have specific needs of various products and methods.
For many years, my mother who was born-raised in UK had a love-affinity for Antique Indian Brass. Surely not to be confused with lesser Chinese thrift store stuff. Very high brilliance and quality, hand beaten-carved.
I inherited all of her better Brass Antiques, two of which are a 30" and 34" Brass Tables on hand figured Wooden Stands.
Now for these, I/We usually did use Brasso. And as you likely know, such a polish can work the bejesus out of you. But the final results are worth it.I also have a priceless Pewter and rose Copper hand hewn Jug that is about 400-450 years old. No recent appraisal, but might guess it's value around $10K. It has been cleaned with Brasso over the years. I cannot see any other product made that would really be as suitable
Yep, you're gonna rub till the cows come home, go through numerous rags, your fingers-hands are black, and sore.
No, I would not ever use Bar Keeper's Friend on these valuable artifacts.
I'd say either one of these Tables is likely worth more than my entire Cymbal Collection.
Here's a short vid and one example of a Brass Table which I speak of.
You note he mentions the use of a Lacquer after to stop further/future tarnishing occurring.
Being an Amateur Astro Buff, I have seen and viewed through fully restored Alvan Clark Brass Refractors, one example, a 6" with a 4" piggy-backed at an Astrofest StarParty. That scope setup is likely worth $60K today. And the views were marvelous, Alvan Clark has gone down in history as a master Lens Maker, largest being the 40" Yerkes in Williams Bay Wisc.
Yes, again the Brass Tubes were sprayed with a protectant product to seal and cease tarnishing.
One thing I liked about my Paiste Sigs, less upkeep. Most important, I fell in love with their sound. Too many and mostly all of the newer Zildjians, Sabians, and all the rest were sounding too much like Garbage Can Lids.
But the New Beat Hats still reigned supreme. LOL I remember having Krut Hi-Hats in the 60's! LOL Again, Garbage Can Lids! LOL
