Thanks for all your responses - for the time being i'm happy with the results of my refurb; however, if static build-up does become an issue in the future, and I decide to anti-static clear-coat the platter, i'll post here with the results, in case anyone is interested.

Thanks Again.

Is there no way to recoat the platter? What did B&O coat them with back then?

I've no idea what B&O used, but there are a number of anti-static products on the market that would do the same job. Most seem to be either spay or wipe on and leave to dry; they leave a thin, clear conductive layer behind, which, I believe, would achieve much the same effect as the original coatings - though I've not tried one out yet!

Hello Dillen,

I have two platters that will benefit from a light cleaning: a Beogram 5500 and a Beocenter 7700, both with some sort of light white rust or similar.
I've understood your advice to not clean them with anything else than a dry cloth because of the coating.

Then i cam across that thread where you unbelievably bring back from wherever it was a Beogram 2000 turned yellow by nicotine.
You obviously did clean the platter too, so I wonder is there something that can be done to refresh the platters, even if complicated or near impossible?
Or is there a rule like "you can do it once or twice in the whole life of the platter but not more" ?

Oh, it has been many Beograms since I did that Beogram 2000 and, I must confess, I cannot remember if I replaced the platter or cleaned it.
If I was able to find a good platter in the dungeons I'm sure, that's what I did.
If not, I might have ended up cleaning the platter as that was the last resort at the time. Certainly the "before" photo suggests that the platter had already
been cleaned (or at least an attempt had been made) at some point before I got it in, since that's what they usually end up looking after the first attempt at cleaning, with the coating partly damaged.

The streaks are not printed, they are stamped or cast onto the platter. It's not a lot but they do have a little height (you can easily feel them), just enough to make the record clear the platter.

The light white "rust" could be oxidation. Airs moisture or some chemical from record cleaners or whatever, attacking the aluminium.
You can remove the white "dust", but there will be scars that can be difficult to remove.

Thank you Dillen (I always feel not "allowed" to call you Martin)

I thought you'll just came with any marvelous answer about "fleur d'oranger mixed with some decoction of tea leaves" which would work flawlessly.
But your actual answer make sense and was what I thought thinking about the dungeon your often speak about.

Wouldn't it be ironic that after fixing the unit thanks to Beoworld topics, sending cells to be rebuild to the guy you recommend me, the weak spot would be aluminium rust with no solution?

Anyway, Thank you..

The solution could be a replacement platter.

And please do call me Martin. I sign my posts that way myself, so it'll be alright.  😂

Martin

Thank you, Martin.
