Client decided to clean her polished onyx bookends by giving them a vinegar bath. How would one go about restoring these to a polished finish? What tools and methods have you used in the past
on a similar project? Obviously there will be detailed work involved that won't involve my floor machine & 17" pads. I have a Makita 9227c, a Dremel, & an orbital hand buffer/polisher.
In the attached picture, the small elephant in the foreground did not get the vinegar treatment and is an example of what she suggested the other larger ones in the background used to look like.
They are about 6-8" tall. Small project, but I'm sure it will be very tedious. They have sentimental value to her, rather than $$$ value.
