Oxalic Acid?

[Varnae]

Has anyone ever heard of this Oxalic Acid? I've read that it is incredible for taking rust off of chrome. I'm thinking of giving it a shot with the headers on my exhaust (maybe the pipes themselves as well) and the engine guards that I got.

From what I've read, all you have to do is create a mixture of this stuff with water and soak what ever you want the rust removed from in it only taking it out every so often to wipe the removed rust off with a sponge or maybe a light scrubbing with a toothbrush. The pictures that I've seen from people that have done it are incredible. Here's a link to what I've found... http://www.vintagebmx.com/community/...wtopic=4004702 Now granted, these folks are doing this to vintage bmx bikes, but I don't think that should make a difference.

My other question is, will it be ok to soak my mufflers? Is the water going to do any damage to the inside of them?

Hmmm... Sounds promising. I wonder what it would do for my black MNS headers! Might be worth a shot. Seems like the issue of getting water in the pipes would not be a problem, since you can just turn them over and dump it all out. Running the bike for a few minutes should be plenty to evaporate any left-over moisture.

There is a product out there called naval jelly which is a rust remover that works really well. It can be a little hard to find, but if I might guess it might be a jellied version of this? You don't have to soak things, just brush it on and the rinse it off. I'm thinking about using it on my Jardine pipes to get rid of the rust at the collectors before I paint them (either black of silver grey).

I used naval jelly on my '68 VW bug's bumper when I was in High School. Works pretty good, but this stuff just seemed to work really well, and covered a larger area with less effort. Of course, you do have to take the parts off the bike before soaking them, and with Naval Jelly, you don't.

XSChop gave me a bottle of stuff that's labelled citric acid. It's a powder you mix with water. It's a lot higher concentration than the average person can get from what I understand... but he says that it will work like this other stuff does. It attacks the rust and encapsulates it, but won't hurt the "Good" metal. He gave it to me to use in my tank.. says it will look like a new one when I'm done and won't hurt the paint or chrome.

I haven't tried it yet so can't vouch... but maybe he'll chime in here with some technicals about it. Either that, or I opened my mouth when I shouldn't have.. lol. (Like that's never happened..)

citric

The citric works like the oxalic acid, except the oxalic is MAJOR TOXIC! The Naval jelly converts the rust to Iron Phosphate and sacrifices some of the base metal, but is an excellent primer. Spray on Rust Converter is the same as Naval Jelly in a spray can......You can also reuse the Citric Acid solution a few times over for other rust removal jobs....

I just finished doing that yesterday to de-rust my tank. It's a little messy and time-consuming to set up but it works. I used TSP for the electrolyte. It's the same thing, basically sodium carbonate, as washing soda.

Loctite product

I used this stuff on the chassis of my 4x4 a couple of years ago and it worked really well. The label doesnt list whats in it, but the tds should be on the web somewhere.

Oxalic acid

About Oxalic acid, rhubarb leaves have high concentrations of the stuff and people have poisoned themselves through eating them.
About the link to the guy getting wondrous results using Oxalic acid to de-rust a kid's bike; I am not saying it's BS but check the April 1st dateline?

Lemons are 4 for a $ at the grocery store this week. Microwave for 15 seconds before cutting in half for more juice.

lemonade

Although lower conc. You could use the conc. lemon juice in the peel cans from the grocery store......get a case tho! if you are doing a tank.....
Ok. I searched around and this is even less expensive than what I have been using......500g will do 2 different 5 gallon motorcycle tanks......Just dump in 250g NaCit to 5.25 gallons of HOT water in a bucket, mix well and then pour into tank, leave 24hrs, 48hr if super rusty......afterwards Dump out while shaking vigorously.....She will clean right up.....After this you can take it one step further by coating the tank inside with Phosphoric Acid (Naval Jelly) Treatment....For a minute or so, Rinse inside out thoroughly and keep it full of gas.....

I use oaxlic on my rusty beer cans and it works well! People also use citric for rust removal as well. Here is a link to some tips from my can site.

I know that works on shower heads, but does it work on metal too? It's really thin, watery stuff, so you'd have to soak in it, I would think.
