A stainless steel wire brush is fine as long as it is clean...maybe some alcohol to remove oils. A little trick is to put a piece of copper behind the hole when welding. The filler won't stick to it.

Slightly diluted "simple Green" ( it's slightly caustic) seems to draw out oils, soak for a few minutes, your biggest problem, followed by acetone or MEK, then alum only SS brush.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

Raised ports eh?
It was like that when I got it. Just a hack job. My sister
could have done a better job. They had just patched over
it with some flakey epoxy. There are several things that
need fixed on this un-cut intake. 
Thanks for all the responses. Looks like cleaning it will be
cheap enough.

don't ever glass bead aluminum if you plan to tig weld it. the glass can impregnate the aluminum and cause issues of porosity in the weld. MEK and then heat (after it evaporates) works well.

I have used a few things, but a new or clean stainless wire brush is the ticket. I also purchased some aluminum cleaner from the local welding shop expensive but it works great. It eats off the oxidation. But Easy off in the yellow can works just as good, and it is much cheaper. Make sure you buy the one that doesn't need you to preheat the oven. Oh and the stainless wire brush is a must. Aluminum will start oxidizing within a couple of hours. I always clean it off really well, then clean it again just before I do the welding.

acetone and a brand new stainless wire brush. make sure you wear rubber gloves while applying the acetone. Some of that stuff will KILL you.

what ever you do, DO NOT use brakleen anywhere within about ten miles of where you are going to weld that.
Thanks, but you're a week late with that advice. Anyhow, tell me why. I'm guessing I was fortunate that nothing happened as a result.
