When in doubt, guys, about a scratched-up dust cover, give this guy's method a try...



For deeper scratches, you may need to polish the covers a little longer, but you can see the difference the polisher makes! :D

And if you have some dull, scratched turntable platters, you could try one of these methods...



There are other ways and methods, of course, but those videos give you a general idea of what you can do...

Yeah, polishing is always easy with the proper power polishing tools. :)

Unfortunately, not everyone has those power tools .

From personal experience I can recommend the NOVUS family of scratch removal aids

I cringe to see someone using steel wool for cleaning hifi, it leaves ferrous residue that rusts. This is 2018, a visit to the PAINT aisle of your local Homedepot or Lowes will turn up lots of nice convenient synthetic (non rusting) cleaning materials, similar to the familiar kitchen scotchbrite products, that cost very little and are available in a variety of hardnesses for steel and aluminum.

I recently picked up a 6" orbital polisher at Walmart for $20 and used it to buff and polish the dust cover on my Yamaha P-350 in addition to the plastic dust cover of an old Sears Tele-Games console storage system. In both cases the results were excellent. It didn't take out the super-deep scuffing on the Yamaha cover, but it still looks significantly better than it did, and really restored the gloss and shine.

Good point. My friend owns a professional buffer, even that struggles to get deep scratches out. If things get too hot it can also warp or cause blooming in some acrylic lids.
I use 1500 grit wet and dry under a running tap, then 2000 grit. I finish off with jeweller's rouge which I dilute with mineral spirits and apply with a cotton cloth. Fairly easy to get a mirror shine for peanuts, and just as good as expensive polishing compounds. Jeweller's rouge is wax mixed with a polishing compound, I use the red one.

Most important thing is having immaculately clean cloths to do the last polishing, acrylic scratches easily and even tiny particles embedded in the cloth will cause visible marks on highly polished lids.

Those cheap hand orbital polishers don't have enough torque to move acrylic, that is what buffing entails.

On that particular lid, single cream. Double cream works better on deeper scratches.

I did the same thing a few months ago, using a 6" random orbit polisher from Home Depot. It was only $19. The 3-bottle kit from Novus was more expensive! I initially tried to use the Novus kit by hand, but unless you have very strong arm muscles, forget it. It would've taken me days or weeks. So I bought the polisher at Home Depot and used it with the Novus liquids, and was able to bring a horrible dust cover back to life in about an hour.

Too bad you don't have a "before-and-after" pic (or do you? :-k)...Would love to see a pic of the cover, though, if you've got one, BMRR! =D>

Picked up a second hand turntable that had deep scratches and was very hazy.

Used my car polisher and car polishing stuff and 5 mins later marked improvement. Could spend some more time and get it better am sure. Was a quick job but seemed to come out well for the little time I Put into it.

It's on the othe part of the forum under "pioneer needle identification"

I have removed some pretty nasty scratches from dustcovers. I have done at least a dozen in the last year. The Pioneer in the photo above can be made to look minty with about an hours worth of work.

The process is almost exactly the same as the wet sanding and polishing that is done to achieve show quality shine on a car paint job.

I use 1000 grit wet sandpaper first. I use water and a drop or two of dish soap in a spray bottle to keep the work nice and wet. Sanding is done in a straight line from front to back. Wiping with a shop towel occasionally to check progress (you can tell when the scratches are gone). Then 1500 grit wet with the same technique. The cover will look quite cloudy at this point.

I use 3M Super duty rubbing compound on a wool pad. I mount the polisher with the pad facing up in the jaws of a workmate. It's a lot easier to hold the dustcover in your hands.

After a couple passes with the 3M compound, I change to a foam pad and Meguiar's ultimate compound as many times as necessary.

The results are quite good. I have done a few for my friends. No complaints.

A little off subject but If all else fails...

I have spent the last few years building a Transcraptors Saturn hybrid and the final thing I needed was a dust cover! The dimensions were outside most commercial supplyers and so I decided on a bespoke cover.

If you live in the UK please contact and trust prdisplays check them out on Facebook or email them prdisplays1@gmail.com for a quote they may also be able to replicate an existing cover which maybe damaged!
