From the Stoner website, I checked with a couple of local stores that were supposed to carry the product, but did not have it.

Finally found it at Checker Auto Parts @ $4.99.

I did all three of my curios yesterday, taking about an hour each to unload, remove and clean the glass shelves and clean the glass and mirrors inside and out, dusting the approximately 30 pieces in each curio, and reloading everything.

They are shining brightly now! Thanks for the tip. It was very easy to use. We shall see how long it keeps looking great.

It had been six months since the last thorough cleaning and the glass was looking pretty bad.
