I wanted to share this experiment as it has so far been quite positive:
I read somewhere that you can remove surface scratches in glass with ordinary paste wax.
I gave it a try on a few of my pins. It really does work. Doesn't seem to work on deeper scratches but the shallow ones are GONE.
I took the glass out and set it on a old cotton sheet. I cleaned it will a quality glass cleaner and then applied a paste wax with a 10" orbital buffer. Dry to haze, buff off the wax and polish. Repeated on the other side. It leaves the glass very smooth to the touch.
Anyone else try this with good results?
The down side is that if you have a cat that like to walk on the machine, they are likely to slip and slide a bit and in some cases, fall off. For older cats, this could be disasterous.
