First foray into derusting with Oxalic Acid
« on: April 18, 2011, 09:07 PM »
OK, peeps.... sharing yesterday's experience with some OA and very hard to reach rust (inside tubes, inside dropout welds etc.)

Mixed it rich (250grams to 4 litres water) and soaked for 30 minutes.

Water turned yellow (think morning after urine) and rust turned whiteish before disappearing.

Thorough rinse in cold clean water for a good while then into the sun to dry out for an hour or so.

I did end up with some tide marks on the chrome / nickel and the odd strange blemishes which I suspect relate to the quality of the rework the Frameset had before I got it. Some Peek and elbow grease soon put paid to those, though.

Now to treat the internals with ACF-50 and we are ready to build.

Sorry there are no pics; due to the location of all of the rust the "Before"s didn't turn out very well.

Still, I can confirm it works, and that any blemishes can be worked out with Peek. I probably would mix it leaner next time around, though, as the fumes were a bit heady!

^^^ what they said about pics

mate what did you use to soak the frame in? been looking for a suitable (and cheap) container as for some reason my wife thinks that trying to make an acid bath using a bin bag and a cardboard tray is a bad idea. nearest thing I found was some underbed storage box but that wasn't exactly cheap

I used a bucket for one end, and then the kitchen sink (the missus was at work) for the other.

Anything made of plastic, porcelain or glass, should be fine.

Clean.

I might actually build a bike this year instead of just hoarding parts :)
