The surface of the turntable of my Beogram 9500 is mottled, spotted & uneven in colour and shininess. Is ther a way to make it even and shiny?
//Bo.A long list...
Oops, there we go again...

Hi,
As said before, there is nothing that can restore the original coating.
What ruins it is 45 RPM records, because you have to use your fingernails to seize them...
I like to spread clear mineral oil and wipe it off gently, till the platter looks matt again. After two or three years you'll probably have to do it again!
Or leave it that way... with a record to hide the misery!

Dear all, Although I do not have more than 6 or 7 Beograms, they all suffered from dirt and not only.
I must admit that I totally agree with Leslie. By profession I'm involved with chemical Cleaners etc and frankly speaking there are ways not to remove any coating.
One solution that can be used is an enzymatic cleaner (e.g. for Endoscopes/Surgical Instruments) which really make the platter look new.
I have treated all of mine since a few years now and there was not even the slightest mark of rust or corrosion etc.
Unfortunately the coating is completely gone, so is there a way to clean the aluminium? I tried most of the chemical stuff you find in a home but nothing helped. Next step will be sodium hydroxide an then furniture polish to seal the surface.
If the coating is gone you have nothing to lose. Go to ICA (since you're in Sweden), in the cleaning section there's a product called "Fläcksuddare", it's around 30 SEK. It's a melamine foam sponge that cleans just about anything. Just cut a small piece of the sponge and add a wee bit of water and the rub on the thing you want to look factory new.
I've used it with great success on my Beomaster 1900 and my Beocenter 9000, among countless other things in my home. I should say that there are other brands of the same product, but the ICA one is easy to get and it's cheep.
Good luck!

There's one guy here who never had dirty platters at all, zero! I managed to clean my platter(s), don't ask me how but I did and they keep clean, no oxydizing whatsoever.

Wrong: The "guy" as you call him, said the he never sold a BG with dirty or spotted platter, he changed the platters with good spotless ones.
Collecting Vintage B&O is not a hobby, its a lifestyle.
@Johan. Thanks for the advice. I´ll try it.
Do try oiling first: nothing to lose here!
Bos00: @Johan. Thanks for the advice. I´ll try it.
Let us know how that worked out. Bought these sponges a while ago on Ebay but no go. What does it do anyway, I mean what's so special about these sponges? If you gonna use them don't use any pressure and always in a circular movement. Good luck, it can be done!

Yes, let us know!
I don't know what's so special about them. I just really like them. Easy to use, great result. It's just hard plastic in a foam form, no chemicals. Easy on both the thing you're cleaning and your hands. I find that the sponge works magic on aluminum (such as the BM1900 and BC9000), and even the lettering does not go away. I've also used it on wooden things to remove marks. It does rub on the surface, so it's probably not a good idea to use on shiny things.
Over here they are sold under the name Magic Eraser, I use them on aluminum (not on TT platters) and plastic, where I can't get it clean with normal cleaning, I also use it around the house to clean where other cleaning products does not do it. After using the moist (never wet) sponge I wipe the cleaned area with a rag moistened with mild soapy water. I have been using it on Perspex (Plexi) lids as a last cleaner before applying car wax or Pledge. On some types of plastic it also helps to take off the yellow on other not.
I cut off small pieces, fitting the lob to do, of the sponge, and after use throws it away, if one time moistened and left to dry its like it doesn't work so good anymore.

I do the same . They are very good. I use them in the kitchen and bathroom too.Not really magic, of course, but still they seem to know what is dirt and what is not.Incredibly good and easy to use.They will not remove oxidation or scratches but on platters they will removedust, dirt and fingerprints. A gentle hand, no soap and no solvents and you will be fine.
Magic eraser is not just a sponge. It has some microfiber structure that performs the magic.I had my doubts too but read about them here and other places and decided that trying couldn't hurt.I was surprised at how well they work.I cannot find them locally, so I buy mine on Ebay. (Don't buy the cheaper ones from China (no offense), theyare just sponges...).

I use them too. Available at the supermarket here!
They are indeed very useful to clean alu surfaces, but cannot restore them.
chartz:I use them too. Available at the supermarket here!
Same here - I love it! It's so effective that it makes cleaning fun - try for example the dirt that accumulates in the wood grain around cupboard handles.
The melamine foam material used in them is an old BASF invention (official name is Basotect - originally used as a soundproofing material!), and it is either manufactured directly by them or under license. I'm sure Chinese and others do a lot of better and worse efforts to copy it.

I hope the FSs don't read this, we will be forced to take over the house cleaning.
Mika you have a knowledge of things I never heard of, impressive.

I'm sure my wife doesn't! Oh well I do it anyway...
I gave it a try, and it worked out quite OK. I'm satisfied with the result. Thanks Johan.
Nice silky matt shine.Looks good and very original.

I'm very happy to hear that. Great job! The platter looks really nice.
Very good Bo, you see, it can be done! Just like mine
