Cleaning brushed aluminium

[skimminstones]

Just bought a primare i21 amp and it has a little bit of discoloration on the front plate and a small yellowish stain too. Anyone know a good way of cleaning these without leaving any scratches or damaging the amp in any other way?

cream of tartar and water in a paste. smear on leave for a while..wipe off and clean with a general cleaner..should come up like new

Cheers for that, will try it over the weekend.

Although im not totally sure if it is discolored or not. Im going by the pics online but they are obviously all airbrushed and photoshopped.

Does this front plate look darker than it should be? Certainly there is a little yellow stain which i want to get out but not sure if the whole plate should be a bit lighter/cleaner or not.

looks to have a few rub marks . Dont see the yellow bit. a non scratch pad and a little cleaner may clear them. those miracle ones are good

yea the yellow but is only small and you cant see it in the pics, only if you stare right at it closely. Ill have a look at what i can get over the weekend.

Don't stare at it, then! WD40 is surprisingly good as a cleaner, BTW.

I have a neff-branded stainless steel cleaning solution designed for ovens which works fantastically well removing fingerprint stains and other marks. It seems oil or petrochemical-based, but is non acidic and should be safe on brushed aluminium. It leaves stainless looking factory new. Isn't that faceplate annodised though?

[struth]

If its anodised then a vinegar soaked cloth or even a paper towel laid on the surface and left for a while should remove it. just wash off after....

I use 3M Stainless Steel polish and cleaner.. very good indeed. It can also be used on glass and I use it on the Formica on my speakers to great effect.
