Elbow grease and any of a wide choice of mild polishing agents. Brasso wadding is my choice. If you have a bezel that needs protection I suggest a sticky (eg mailing) label cut to size with a circular cutter.

I can take a look later, but there are many good threads discussing this topic in detail.

If the scratches are deep, a liquid polish will not be enough. I generally use Novus #2 or Polywatch for a final polish, but deeper scratches need something more aggressive first.

That works well for me.
Great to know. Should I use a microfiber cloth or a lens cloth.

Microfiber would be fine, but almost anything works. It's just a plastic crystal and it's never going to be perfect.

I restore old watches and I found that for light scratching polywatch is the way to go. If the scratches are deeper then I use 1200 wet and dry with soapy water. Cut down the scratches and then finish with polywatch.

mind you all the above are great ways too that I am going to try also but the way I do it seems to work with terrific results so I thought I’d share.
Good luck, hope it gets cleaned like new.

Please make sure it is at least 1200 grit or smoother or you will end up making it a harder time to polish after with polywatch. The sandpaper is to remove the scratches and the polywatch is to remove the Sanpaper scuffs.

the crystal will go milky and you won’t see through it when you sandpaper it with the soapy water. Don’t worry it all goes clear and new when you use polywatch and a micro fibre cloth.

Will do! I am going to just try some elbow grease and solution at first.

Polywatch is great for minor scuffs and light scratches. For anything more than that, how aggressive you start will depend on how deep the scratches are. Here's an example I've shown before - very deep scratches on this crystal:



Started off with coarse film - pretty sure it was 150 or something like that - yes it will look worse before it looks better:



As with all polishing operations, you need to move incrementally through the grits, making sure that you completely remove the scratches from the previous grit before moving on. I work my way through grits up to 2500, then to 5 micron lapping film, then 1 micron, and finish with Polywatch:



Bit of dust still on the crystal there, but the final result was quite good:



Cheers, Al

Came up well. That’s the reason I prefer an acrylic crystal. You can repair the scratches without the need of replacement.
