Cleaning Aluminum, Suggestions for chemicals to use Options

[John]

I would like some suggestions as to what to use to clean and "brighten" aluminum such as an engine case.

I don't want to media blast the case. I know this would clean it but would end up leaving a more rough surface finish that I would like.

I would like to use some sort of cleaner/brightener. I plan on using a pressure washer or a spray type parts washer.

In searching the web I have found only a few types that can be bought in small quantities (like a gallon).

Thanks for your advise.

Find out what the price is and PM me back. I might be able to get it cheaper (read: Wholesale) from a Johnstone Supply near you and put it on 'will call' at the cash counter.

And the statement above about it being too caustic for aluminum is pure BS, that's what it was formulated for. (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif)

"Have you used the stuff and know it to work well?"

I've used it for years on various aluminum items (EAC's, alum. filters, Air conditioner coils, etc...), but not on an engine block (yet). I have a spare short-block (filthy) sitting out back, and a little coil cleaner left in the jug, so as soon as it stops raining (Weds.
