Aluminum foil + Coca-Cola + Motorcycle = Yes???

Did you try it w/o the coke? I've used tin foil before not sure what the coke adds other than stickyness.
 
I fell for it. I watched that video twice trying to find where you dealt with the heavily rusted piece in the teaser picture.

I've tried the coke and tin foil on rustier pieces than the one in the video and was disappointed, but I guess I was asking for too much. Electrolysis on the other hand.... that it is like magic.
 
Coke has phosphoric acid in it.
.05%. The concentration is about 500x weaker than a mild rust remover, Coke is basically a lubricant - your simply scrubbing off the rust with the foil.

Coke’s concentration of phosphoric acid is too low to release rust let alone convert it to black iron phosphate.

The black/grey stuff in the video is aluminum oxide and nothing to do with coke - you get the same byproduct with water. The reaction is between aluminum and iron oxide (rust).

Coke will release rust simply by submersion without any aluminum foil or abrasion required.

It’s dilute but that just means it needs to be replenished more often, and will take longer than using a more concentrated acid.

So... trying to spell this out slowly because concussed brain no fast think...

You're saying the black ooze is from aluminum rubbing up on rust, not from the coke mixing with the rust, is that correct?

If so, I might have to go back out and retry this on the next rusty bike in the garage... luckily there are many **** boxes in there for me to choose from lol
 
Great tip. Wondering if vinegar would work as well?

From the research I did, yes it would work but you don't want to use vinegar...

(Science words go here, yata yata yata), so I think with vinegar there is a chance it will "flash rust" again... BUT coke will actually magically turn the old rust into a protective barrier instead of just dissolving it, because of (more science words go here).

Google it though if you're curious! These things are beyond my metal mental capacity scope right now.

Oh man, sorry. Do you guys think I should change the thumbnail?

I know nothing about electrolysis. Teach us all Nuggy!

Yep. I think that's why the poor man's de-rusting of a motorcycle tank, if you don't want to spend money on the actual acid, is to just pour coke in there.
