Author Topic: Cleaning Rust Out Of A Gas Tank With VINEGAR!!!!!!!!!!!!!!!!!!!!  (Read 33840 times)

I recently read here or on another site of a way to clean rust from within a gas tank for $30.00 and does not require coating. It is very simple to the point of being unbelievable but it WORKS!!!! First buy a large box of 1" long sheetrock screws, $20.00. Then buy 4 gal's of white vinegar from the grocery store, $10.00. Then simply insert all the sheetrock screws into the tank, close the cap and shake the hell out of it by hand. I shook it on and off for a day. Every time I walked past it I would shake it. This process knocks off all the loose rust within the tank. I removed the screws. Then simply filled the talk to the brim with vinegar and closed the cap.  I let it set for two days. I then poured out all but approx. 1/2 gallon of vinegar. I then added the sheetrock screws again and shook the hell out of it again. Removed the screws again and refilled the tank with the same used vinegar. Let it set another day. Drained the vinegar out and flushed the tank out with a water hose. After flushing it out, I immediately poured Coca-Cola into the tank and sloshed it around good to keep it from flash rusting. It was that simple. It took it down to bare matal......... Mine looked so good after that I didn't even have to coat it inside.     The first picture below is of the large pile of finely powered rust dust that came out of the tank when I emptied the screws out.

sweet. i've read about the vinegar technique a few times but it's great to get pics and positive feedback. the coke trick sounds like a charm too. thanks for the pointers.

just a few questions though, did you reuse each of the emptied lot of vinegar when you refilled?
also, if you weren't, how were you getting all the screws out for both occasions? did you just empty the whole tank and get the screws out and then refill?

Yes, I reused the vinegar. After filling and shaking the tank, I emptied the vinegar out as much as I could into one 5 gal plastic bucket.  I then turned the tank upside down and emptied the screws out on a large sheet of plastic on the ground by shaking the tank till all the screws fell out. Then I let the vinegar sit in the bucket till all the rust  settled to the bottom of the bucket. I then poured the vinegar into the another 5 gal bucket through a cloth filter. I did two tanks with it and still can reuse it again.............

could you use anything other than sheetrock screws, like nuts?

Yes you could and I have tried other media and the sheetrock screws work the best because they have the pointy and sharp ends which help break up all the rust scale inside the tank.

Why Coke to stop it from flash rusting? ??? Carbonated water is still water isn't it?

And wouldn't the sticky coating left by the soda syrup on the inside of the tank have any negative effects on gas you put in it afterwards?

Great to hear someone with success from the Vinegar method tho. I need to clean out my KZ400 tank and have been looking for the best "budget" way to do so.

The Coke is added because it contains Phosphoric acid which neutralizes the acid in the vinegar....
Vinegar is an acetic acid solution in water (5-9 %).
As far as any syrup left inside the tank, I always rinse the tank out with some gas before filling the tank.

Damn.  Now I'm craving chips with vinegar.
"Quality . . . you know what it is, yet you don't know what it is. But that's self-contradictory. But some things are better than others, that is, they have more quality. But when you try to say what the quality is, apart from the things that have it, it all goes poof! There's nothing to talk about. But if you can't say what Quality is, how do you know what it is, or how do you know that it even exists? If no one knows what it is, then for all practical purposes it doesn't exist at all. But for all practical purposes it really does exist."
