Any ideas on a good chemical that is easy to get hold of to clean up white powdery oxidized aluminium parts with intricate nooks and crannies that a wire brush will not get into? I do not have access to a sand blaster either.
Cheers G.

You could try using Ferric Chloride. It's what I use to etch brass copper and aluminium. Available from Maplins. Warning this is very nasty stuff, especially when used on aluminium. I take no responsibility for damage, injury or death.  No, really. |

It's simple. Just degrease, paint any area you don't want etched (or use lettraset), then stick it into the acid until you have the required depth of etch. Given enough time though it will eat under the paint so there are limits on how deep you can etch.

Sounds like a similar process to electrolysis etching.
