Using citric acid for rust removal
Loading...
Uploaded by FuelFetish on Jun 17, 2008
Citric acid can be bought from drugstore (they use it in jelly or such to adjust acidity) but it is very expensive there. Therefore Finnish rodders buy it from some agriculture-store. It is not expensive. Officially it is used as pigs obstruent! I dipped those parts in citric acid for overnight, next day brushed it with wirebrush and flushed it with water. Then again back to citric acid over night and wirebrushed + flushed it next day.
Flushing is important, you'll want to get all acid away, otherwise steel will turn to yellow.
You can't use this method on all parts because of hydrogen embrittlement. So no pedals, frames, brake drums, engine blocks or such to citric acid!!! And yeah, parts should be clean -I've cleaned 'em with fuel- because grease will neutralize acid. Ratio was 3%
Parts must be dried soon as you get them flushed, I quess you guys know why...

How 'bout a small angle grinder with a wire brush tool on it? Takes far less time to do the job, doesn't require heating the damn thing with a blowtorch and it's really inexpensive.
-
Hydrogen embrittlement can be avoided using molasses and water.

@dreamsfgh Police use it [Coke] to clean blood off the Highway after accidents. Coke is shit.
-
@LYinKansas Pepsi & Coke both contain Phosphoric Acid [food acid], which coverts the rust to iron phosphate.
-
Phosphoric Acid for light surface rust, Tani Acid for heavier "flaky" rust. Will do are far better job, than Citric.
-
for drying , why not simply wipe it with a cloth instead of using hot air ?
-
@snakeoil24 Agreed
