Predicta Holiday - my first Predicta!!

[StellarTV]

I would like to remove the front plastic CRT cover and clean it.

Yes. If there are no deep scratches and you'd like to add some shine and there is zero to only just a slight amount of mold, I highly recommend a microfiber cloth and some Meguiar's Cleaner Wax. Adds a high gloss 'slick' finish. (yes this early plastic formulation decomposes, similar to many radio knobs of the era. Yours appears to have some decomposition.)

I had one Predicta faceplate that was completely covered in what appeared to be a white powder... it was so thick that I had to scratch ALL of it off with my thumbnail. Soft enough as to not scratch the face. I ended up with a big pile of waxy, smelly plasticky powder but afterward it was possible to buff it out.

Jury says that in another 50 years there may not be much left of many of these Predicta faceplates that have started to decompose. We will see.

If the cover has scratches that you want to work out, that's much more involved, but can be done by feathering out deep imperfections with progressively finer sandpaper. Start with 400 (for deep cuts) or start with 800 (if there's nothing too objectionable) then progress to 1000, 1500, 2000, then a final polish. I like to apply plastic polish, which is available in stick form, to a loose cotton buff and work it over on the buffing motor.
