Removing light scratches from clear plastic windows

[LGB333]

Does anyone have a good technique to remove light scratches from locomotive or rolling stock clear plastic windows? I accidently put some light scratches on the inside of a couple LGB caboose windows when I was installing LED light strips.......the strip corner rubbed onto the two corner windows.

I might try on a test piece of clear plastic a very fine auto paint scratch remover and then use an auto polish compound to buff it up?

I once heard it said that Brasso might do the trick, if you have some worth a try. But experiment on a piece of scrap clear plastic first please before you blame me that it does not work!

I seem to remember using toothpaste years ago on scratched car windows and screens on Airfix kits (plus the cockpit canopies on the aircraft ones).

What about the stuff sold for cleaning automobile headlight lenses ?

Not long ago I used "shiny sinks" a stainless steel cleaner, removes the scratches, however leaves a slight "bloom" I then loaded a coat of "kleer" floor polish which fills in the fine scratches left and the window looks quite clear!!

Certainly have, been edited.

Some interesting ideas..........I have lots of spare clear plastic pieces from Pola and Piko buildings to try these on. Thanks all!

tooth paste works pretty good

Tom, I have a number of pinball games - yes, the large, heavy, noisy games that you put money into to play. There are a lot of plastic items in one of these games. On the games the plastic pieces may get scratched. Traditionally, we use a plastic polish product produced under the Novus brand. It is available in three versions, depending on how heavy the scratches are. I would suggest trying one for fine scratches first, Novus #2. Novus #1 is a clean and polish, and Novus #3 is for very heavy scratches. You can get Novus from most pinball part suppliers, or, perhaps, easier from Amazon.

I have also used toothpaste, but Novus seemed to work better on the plastics used in the pinball games.

Good luck!

There is also plastic polish for plexiglas sold for cars and airplanes for many years:

I've used the Novus products since 1967. (motorcycle helmet visors first)

Great...........I'll definitely get the Novus product to test on some clear plastic pieces to learn the technique, then on the caboose's two little windows.

Muchas Gracias!
