The Plastx does an alright job, had some hairline scuff lines on my PSA 9 Fossil Dragonite. Cleaned it up quite nicely.




Tried it on my old scuffed up case PSA 6 Blastoise, has cleaned it up nicely. It still some scratches but not as bad as it was  
 



If you continue to do repeat applications you can get at those deeper scratches too
How did it work?
I’m going to attempt using a dremmel with a small compound pad and some mothers mag and aluminum Polish on some cases. I will let you guys know the results but my bet is it will come out perfect if done properly.
Last night I did a few more applications and those deeper scratches are almost gone just tiny left over dimples in the plastic. This stuff does an great job if you put a bit of time into buffing.
Without the deep scratches on the case I can now see the card more better. It is good to see the case restored 
Funny to see people discussing how to remove small scratches from cases that describe the condition of a children’s playing card game. How ocd and in to a hobby can you be…
I’m buying a bottle  .

This thread is a lifesaver, thank you!
I found this thread sometime last year and have since made a “how to” video showing before and after shots + my technique. Just in case anyone wanted anymore info about it.
One last test on a PSA 10 Team Rocket Squirtle which had some nasty scratches on the case.
Unsure if link will work, Imgur is new to me:

Ask’s Fiancee - “How late is the hardware store open?!”… “Well do you have any unscented toothpaste?”
So glad this thread popped back up. Was in the middle of scanning my collection and noticed a few cases that have some decent scuffing. I’ll post some before and after once I get some polish!
Just did one pass over 3 different cards. For reference, these are all PSA 9, mostly due to back whitening/centering. They might have a scratch or two on the holo, but nothing that sticks out. I’ll probably go over these a couple more times to clear up what remains. Extremely happy with the results (I used some PlastX I got from Walmart).

I’ve used Iosso, a generical polishing cream. It works very well. But I imagine that a plastic polish is much better. I’ll try to find that PlastX here in Italy. Thanks.
@benoit489 The Magneton without eyes looks pretty cool, haha. 
But I’ll have to bookmark this thread and clean some of my earliest bought cases. Especially this MAP-graded one…

If I remember to do so, I’ll post an after picture later on.  Currently don’t have the time since I’m about to go.

I’ll have to try this. Has anybody tried using a CD/DVD scratch remover? I wonder how the options compare.
I am reviving this thread if possible. I would like to try this because somehow when I sold a $2400 card flawlessly, it got a scratch on the case with double protection and the buyer asked to return it. I am going to try and buff it out and upload the results once I receive my card back.

I tried this recently and uploaded it to my channel. Worked wonders   - YouTube

Awesome, thanks! @xgav1337x @pokeaddict84
