Default How to get rid of aluminum corrosion?

I got a newer motor for my ITR to replace the old one, and i worked all week so i let it sit in the garage under a tarp. Well, one night the garage started leaking and it got really moist in there, to my suprise two days later the engine now has a white powdery substance all the time now, even after i clean it. Is there some way i can get rid of this stuff completely?

Hardware store. I saw it at Meijers one day. They actually sell it for cleaning concrete, so look in that section.

Also, "The Works" toilet bowl cleaner has a high concentration of acid in it too.

But beware, acid + aluminum = gas byproduct. I'll let the chem majors figure out which one Click the image to open in full size.

Also pool supply stores. You may need to thin it with water however.

Wear rubber gloves and eye protection. Muriatic acid is nasty and will burn your skin on contact.

After cleaning and a THROROUGH rinse, use some polished aluminum wheel coating, or a good wax to 'seal' and protect the aluminum from further contamination.

I know of other, really interesting uses for "The Works" toilet cleaner and it has to do with aluminum, but I'm not going to say what it is Click the image to open in full size.

Actually, the best way to protect from further corrosion is to leave it as is. Al203 is a hard ceramic, and further protects the aluminum from corrosion. In fact that white chalkyness reduces corrosion to .05mm/year... the definition of corrosion resistant aluminum.

Muratic acid is also found in rim cleaners. Detailers call it "wheel acid" - gets brake dust off really well.

It also takes off the bronze-y coating on the R calipers - ask me how I know Click the image to open in full size.

muriatic acid is a pool cleanser, and is not paint friendly.

Default Re: How to get rid of aluminum corrosion? (Captain Commando)

I know exactly what your talking about. I had that stuff all over my B18C in my GS-R. It usually happened when I let the car sit for a while. Plus, the wet weather around here eats up metal like candy. The gas thats given off by the aluminum-muriatic acid reaction is the diatomic version of Hydrogen...Hydrogen gas (H subscript 2). Most metal-acid reactions produce hydrogen. It is a Redox Reaction. I would just leave it alone if I were you. If you pour corrosive chemicals all over the aluminum parts its not only going to slowly eat the metal up, but all the rubber and plastic part will be adversly affected too.

I used aluminum jelly to get oxidation off an old block I got a year ago. Picked it up at my local hardware store.

muriatic acid worked great, just be sure not to wash it off with water and just wipe clean. If you do wash it off with wtaer the corrosion will just come back.

I used some chrome polish after to seal everything up, i hope it lasts.

Plastic and rubber are imperiable to muriatic acid. I dumped a bit over the rubber gloves and it just sat there and didnt eat it up.

You're confusing the corrosivness of muriatic acid with HCl or H2SO4. Muriatic doesn't eat rubber up before your eyes...it makes it weak, brittle and hard over time. Muriatic acid, although still corrosive, is mainly used to adjust alkaline and pH levels of swimming pools.

I used a 3m cleaning pad, and 18v drill on high speed to get rid of my corrosion, then either painted, or polished the metal after.
