Hi Rolf: I have used NOVUS products to remove scratches from dust covers: https://novuspolish.com/ The stuff is very good for removing the haze on the the acrylic. Light to medium scratches can be removed but may take some time. For example swirls from dusting can be removed very easily. Tip: Use a cloth like a used T-shirt to clean and polish. Don't use paper towels. Deeper gouges that you can feel with your finger will take more effort. You may have to use a polishing wheel etc. There are a number of Youtube videos showing how to remove scratches from the dust covers. Various techniques and products are used. Here's an example: https://www.youtube.com/watch?v=GBZ0iHo4Kdo   Derek

Rolf, For something like this, technique is much more important than the product that you use. There are hundreds of plastic and car polishes that can be used to get great results. Polishing is a multi-step process where one progresses though ever finer polishes until the desired results are achieved. The aggressiveness of the products that you use depend on the problem you are trying to fix. Deep scratches may need to be addressed with sandpaper, light haze might only need a final polish. A few tips...

• Practice on a junk cover to develop your technique. Thrift shops are a great place to find these inexpensively.
• Remove any metal trim or brackets if it is possible to do so without damage. Mask any trim that cannot be removed. (I hope that it is obvious that the cover should be removed from the turntable ;-) )
• Use the least aggressive polish that will fix the defect. Using too fine of a polish usually does no harm. Too coarse of a polish or sandpaper (or paper towels) will add new scratches that you will need to polish out.
• Microfiber cloths are ideal for this
• Using a machine will speed up the job. It can also speed up the severity of your mistakes. I prefer random orbit over rotary machines.
• Securing the cover so it will not move makes polishing easier and reduces the possibility of unintended damage
• Don't try to polish the inside of a dust cover. It is usually not necessary and the inside corners are impossible to polish
• A (new) reproduction cover might be available. This could be a good option depending on your skill set and how much you value your time.
• Don't forget to post before and after pictures ;-)

Hey guys, really thank you for your responses. I forgot to turn on subscription, so I became aware of your support only when I checked on the forum last night. @Derek: Thank you for pointing me toward the novus polish, it seems to be a real good one. I must admit that I was being impatient and ordered meanwhile the Mer polish. As you said, I think that paper will not do, so I ordered some specific cloths for polishing. "Deeper gouges that you can feel with your finger will take more effort. You may have to use a polishing wheel etc." --> At the moment I will go only for the lighter ones, because in this case I do have no experience at all. Since I am trying this for the first time, I find the video very helpful. I did not check the scratches in detail yet, from the first looks, they seem to be more of the lighter kind. @Glitch: Thanks for your comprehensive tips which surely will support my endeavour. Here we go: Practice on a junk cover to develop your technique. Thrift shops are a great place to find these inexpensively. --> Very good idea, I have a spare dustcover - ruined by a B&O repair shop - I can practice with. Remove any metal trim or brackets if it is possible to do so without damage. Mask any trim that cannot be removed. (I hope that it is obvious that the cover should be removed from the turntable ? ) --> Mmmmh ?, according to the pictures in the book, I thought I could get away with the dustcover still assembled on the BG. I have disassembled some parts of a BG before, but never a dustcover. I will check on the service manual. Use the least aggressive polish that will fix the defect. Using too fine of a polish usually does no harm. Too coarse of a polish or sandpaper (or paper towels) will add new scratches that you will need to polish out. --> Right now I would go only for the light scratches, having no experience at all. I have read that sandpaper will take away deeper scratches, e. g. taking care of the speaker displays of BL 3000, 4500, etc., but for this I definitely need more training and experience. Microfiber cloths are ideal for this --> Got me some. Using a machine will speed up the job. It can also speed up the severity of your mistakes. I prefer random orbit over rotary machines. --> At first try I will go manually, which should be good enough for lighter scratches? Securing the cover so it will not move makes polishing easier and reduces the possibility of unintended damage --> O. K. Don’t try to polish the inside of a dust cover. It is usually not necessary and the inside corners are impossible to polish --> I did clean the inside of the cover and it seems to be good. A (new) reproduction cover might be available. This could be a good option depending on your skill set and how much you value your time. --> Time is a good point ?. I did some repairs myself in the past and now want to get more things done, because the people knowing how to take care of the old B&O stuff are rare and getting even rarer now. Since my time during the year is really limited, I have to go in small steps, although having an ever longer list of projects I want to start with. So in between holiday season and new years day, dustcover repair it will be. Don’t forget to post before and after pictures ? --> Yes! I appreciate your advice a lot. Get some rest, happy holidays and stay healthy! Kind regards, Rolf

So, here are two pictures after I was done with cleaning the BG on the outside. The scratches cannot be seen on the pictures but I find the BG really beautiful: Login to view image Login to view image After a demanding year I need to take a breath now for the holiday season. After that, I will take the RX2 out of its storage and post more pictures and let you know about my success. And, if time allows, I will administer the procedure to my BG 9500, 3300, .... Kind regards, Rolf  

I'm currently working on a Beogram 8002 and its dust cover needed some work. Here is my setup. Login to view image   This cover had some pretty deep scratches. I started with 1000 grit sandpaper. Here is a picture of one of the scratches after a light 1000 grit sanding. Login to view image   I stepped through 1000, 2000, and 3000 grit sandpaper with an occasional rough polish to check on the progress. I had to make several loops through the 2000 to rough polish stages. Once it was "good enough" (i.e. I got tired of working on it for the day), there was a final fine polish. Here are some before and after pictures. Login to view image Login to view image Login to view image Login to view image Login to view image   The cover is reasonably presentable now. I plan to do a couple of more loops starting at 3000 grit to perfect it. I also need to do some work on the inside of this cover. The turntable was shipped with the platter installed (and the suspension not locked down). The platter left some pretty nasty gouges on the inside of the dust over. Rolf:  It looks like your cover is starting in much better condition. It should be a pretty straightforward job to perfect it. Glitch
