Where else than on a female riders forum would this q'n be most at it's place

My 'problem' is this.

Over the years my alu parts have kept nicely clean on the polished side, but on the back there is no smooth polished surface and one can see that the pores are full of stuff that isn't nice to look at.

Now there are probably several options to tackle this, but one of them is allways chemicals and such and i don't want to go that route.

Now isn't there a household liquid or such that does the trick.

So far is used just the average soapy stuff to do the dishes with and to a certain level it works, but i just want to go all the way and get it like it was when bought new.

Fill me in as i read it with much interest.
