Care for your CRYST base
How To Care For Your Crystal Bases
Wood and white marble bases only require dusting as necessary. However, if your set comes with a brass base, extra care needs to be given.
Over time, brass can lose its' shine as oxygen, water, and touching brass can cause the metal to tarnish.
Dust your brass base first, and then polish with a soft cloth and brass or stainless steel cleaner. This will bring lustre back to your brass base.
Using a brass cleaner will also leave a protective coating on the surface which helps prevent future tarnishing.
