What is a good polish for black acrylic?

The Best I have is PLEXUS,www.plexusplasticcleaner.com.
Music Direct sell it, but it`s all around at car dealers and
motorcycles shop.It`s the BEST.

I agree with the suggestion for Novis.

The only other cleaner-polish that I feel is equal is ROR. ROR stands for residual oil remover and is designed for cameras and high quality optical products. NASA uses this and treating a high quality camera lenses will actually delivers MORE light to the film (or digital pickup).

Link to home page if you wish to learn more. I have been using this and Novis for many years and love both products. The neat thing about ROR is it removes all traces of previous treatment without harm.

Well, for starters I used Google and found this:

If you don't want to wait for it to be shipped, I've seen Novus for sale at upscale hardware stores, a few Home Depot's, almost every Container Store and many plastic's supply houses (look in local Yellow pages "Plastics").

Here is a link to the Container Store page with location listings. With luck, you live near one.

What about the clear plastic covers for turntables? I just recently got a used one in the mail and it (cover and turntable) were taped together for shipment, but i can't seem to get the residue off the cover. The tape used was clear packing tape. I've not done anything yet to try to really get it all off because i thought i might damage the plastic. Would this polish for plastics work? robert
