Aluminum fuel cell cleaning

I bought a used aluminum fuel cell. I removed the foam from the inside to check out the condition of the foam I looks good with no apparent deterioration. The cell itself must of had gas setting in it for a long time as the inside is scaly about half way up the sides. Need ideas on how to remove the scale. Chemical or blasting?

Use some 400 grit sand paper

Get some aluma bright from a truck stop or ebag.

how would that work if you can't get your hand inside to polish it ? or is this an etch type liquid ? sorry to sound so dum.....

It's a mild cleaning acid. It won't eat the aluminum.

thanks ! you just learned an old dog something new. [now if i can just remember it....]

I sent off a e-mail and asked if their aluma brite would remove the scale build up inside the tank cause by old gas. Their reply was to use Sta-Bil . Little to late for that.

Chief aircraft and Aircraft Spruce both sell a liquid aluminum corrosion remover, maybe the name is Aladyne Maybe not it's been way to long since I've bought and use it on my old airplane It works very well doing that corrosion scale removing
Call them to get some
I have also used Eagle Cast Aluminum wheel cleaner on intakes to clean them up so they look good

Sold by the brand name Alodine.

Also available on Amazon.

That isn't the product I'm thinking of, I believe that is a sealer and corrosion preventer, not the corrosion remover I'm thinking of

Must be that Aircraft and Mopar are synonyms . I could buy a new fuel cell for what their products cost. Still didn't find anything that will work for removing dried gas build up.

Try some easyoff oven cleaner. It takes burnt oil off coated headers if u let it soak for a while. Give it a shot.

No way in the world would I use Easy Off, or any oven cleaner,on aluminum, unless I wanted it to disappear

Try some carb cleaner.. I like chemtool's B12..

Metal Prep by Amchem has an aluminum formula. I cleaned an intake, but I also could scrub. I don't know if it works by dwelling or not.

It doesn't harm aluminum, I tried it.

That really surprises me, I would have sworn I remember some one screwing up a AFB by spraying it with Easy Off to clean it
