Quick question, I am thinking of trying Simi-Chrome polish on my newly acquired and formerly VERY dirty Beomaster 1600 aluminum parts.
I asked eons ago vis-à-vis using this product to polish the polished aluminum panels on my Beomaster 4500 and was told this was a DEFINITE NO.
Fine, I got that. However the Beomaster 1600 has burnished aluminum.
So would it be safe to try a specific polish designed for aluminum on a burnished aluminum surface?
I am thinking it might get out some of the dark spots the rubbing alcohol failed to remove while providing a nice soft shine.
Or are polishes of any kind best avoided?
Any thoughts?

Try first with Mr. Clean Magic Eraser

The aluminium on the Beomaster 1600 is not burnished, it's eloxated.The very thin eloxated aluminium surface is one of the hardest and toughest materials on earth (harder than diamond) - but it's onlya very thin layer and it has nothing but soft aluminium behind it, so it will withstand quite a lot when it comes to normal use, wear and tear butwill be damaged from tough handling, dents etc..The eloxated surface cannot be restored easily, it will have to be removed and reflowed.Scuffs from plastic etc. can often rub off using Magic Cleaner sponges with a tiny drop of water.Chemical damage and deeper marks are here to stay.

Only a few damages can be repaired. But eloxated alumenum is one of the most difficult materials to be repaired.
Oh boy, am I ever glad I asked this question.
Both the Beomaster 1600 and Beomaster 2400.2 have been restored to a most acceptable cosmetic level and it would have been a terrible shame to have ruined the aluminum panels.
From the beginning with this two Beomaster project I erred on the side of caution starting with the benign vinegar based Windex, but it quickly became clear that something stronger was needed. (The crud just laughed at the Windex.) I then went to rubbing alcohol which made a considerable difference.
I completely forgot about the Magic Eraser and that might be worth a try on the few remaining scratches that have dark dirt in them. Thanks Søren.
I especially want to thank Martin for preventing my making a very unfortunate mistake. It is my darn jeweller’s background getting in the way of judgment, as with jewellry, no matter what the problem, polish it. (except for rhodium plate.)
Pictures? No problem.
Thank you gentleman, as always for your help and advice.
The above photo has nothing to do with the exterior cosmetic condition, but speaks volumes vis-à-vis the overall condition of the Beomaster 1600. This photo shows the damage to the Beomaster 2400.2 rather well.
This is the "after" photo of the Beomaster 1600.
Lastly, a Beomaster 2400.2 that was destined for the trash bin. When offered I hesitated as I already have a near flawless example, however the Beomaster 2400.2 was a "package deal" with the Beomaster 1600 that I DID want. Suffice to say I am very, VERY glad I took on this project. Thank you again gentlemen with your help with the bronze prongs.
I just tried the Mr. Clean Magic Eraser (which I use for my styluses) on both the Beomaster 1600 as well as the Beomaster 2400.2, in no small part because both Søren and Martin recommended this product and with two such endorsements, I was compelled to try it.
I beavered away (this is a Canadian term) on the aluminum for about 20 minutes with no effect, which is really not much of a surprise when considering the hours I spent with rubbing alcohol scrubbing both these Beomasters repeatedly. The Magic Eraser did no damage, but it didn’t make any improvements either….. but at least I tried and still a very good tip.
THEN I noticed, completely untouched and unmolested, the plastic tuner belt on the right side had completely broken apart. Sigh. Not a good sign by any measure I comprehend.
Tomorrow I plan to test for power before and after the switch. If there is power, then the power supply is OK (which would be very good) then time to de-solder the switch wires and take the switch apart.
With a good deal of luck, the switch has failed for one reason or another (that’s what I am hoping for) and once bypassed I can see what happens when the Beomaster 1600 powers up.
If the 1600 powers up I can then address what can be done about the broken tuner belt and ask Martin about one of his clutch kits.
Funny how these things “evolve.” When all the controls had been cleaned they all worked well, except the volume control. Now virtually all of the selector clutches slip.
The clutches slip and the selector cord breaks: I see a good deal of progress evaporating before my eyes. Hopefully tomorrow will go better.
Piaf:This is the "after" photo of the Beomaster 1600.
I see your problem, ugly marks, and just where you dont want them, at the logo, I have a lot worse on my pizzabox stack al of them with ugly marks and scratches, but the BG looks nearly good, so when stacked one cant see it and the fronts are pristine. I have wasted hours polishing and cleaning all to no avail.
before checking the main switch pull the 2 fuses sitting just before the transformer, when you have power established put in the fuses again, cross your fingers and power on
Hi Søren,
I missed your warning as my email notifications have ceased to function. I mentioned this to Keith, but so far, no post notifications appear in my email box.
None the less the Beomaster 1600 survived and tomorrow is the big day to test all the fuses. Assuming I find one or more blown I will need to go to downtown Victoria for replacements on Monday. (They are closed on Sunday.)
Wish me luck! (I may well need it.)
