The alternator....

I may have dreamt this, but I thought there was a product on the market for typing up cast aluminium. My alternator looks a bit grim on the outside.

This stuff maybe?

(no personal experience of it though).

That could be it. I'm sure I'm thinking of a paste you smear on that removes ally oxidation.

I've never used it, but this comes highly recommended by friends...

EDIT: Oops, too late

Maybe you're confusing that with Naval Jelly (by Loctite) which removes rust oxidation from ferrous metal?

While Googling around, I did find this however: https://www.amazon.com/Henkel-01-802.../dp/B000BZX3PI
... which is the only ad for it I could find for it, and appears to be NLA anyway!

Muriatic acid, Phosphoric acid or Hydrochloric acid would also do the trick I think, but I wouldn't fancy getting any of them near my car at all, let alone in any concentration likely to be effective. Try to explain that to the insurance company when your engine spontaneously catches fire as a result of cleaning it! All in all the Race Glaze product sounds the best one to try?

The problem is the product I suspect you are after contains Peracetic acid, I am not exactly sure when but the EEC restricted its use, apparently it could cause bone cancer.

As has been said all the products now contain other acids but are not as good as Paracetic Acid.

My new Alternator in black does look a lot better than the original for this very reason.

I'll give the raceglaze a try. I'm not a great one for cleaning the engine bay, but the alternator is rather in your face in these cars. Thanks all.

Do not get that product anywhere near plastic as it’ll stain it white. It’s a good product but it’s harmful to plastic

There's always Solvol, fine wire wool and a lot of effort!

Always works, but at my age I simply don't have the years left I imagine!
