anyone here know what cleaning agent to use to clean the aluminum window frames which have turned yellowish?
In order to save cost, I would like to try if there is any way to clean and restore back the aluminum frames to its original color (silver)??

please help..

Aluminum, like any other metal reacts with oxygen over time and loses its luster and shine when you first purchase it.

Try cleaning with a mixture of vinegar + water, tell me how it works out

thanks alot... what is the ratio between vinegar and water?
i will try it out this week.. will let u know the result.

Try the BRASSO. Either come in tube paste or liquid. Can get at hardware shop.

It is for any metal that the surface is oxidize and dirty stain. Very effective. But for aluminium, there possible got 2 outcome result after apply. Either shinning gross or aluminium mate. Try it with small potion first and see the result.

thanks bro.. will try it too.

Scientifically not very true, Aluminium is a kind of metal in which according to the periodic table, it is very fast oxidize and leave a layer of alu oxide on its top coat, this layer will keep the aluminium in shinny surface and that is why you will never see aluminium rusted, this is what I learnt during materials engineering

but what i can see on my aluminum frames are yellowish stain and not shiny at all. So is that Al2O3 too?
