Rust Removal and Prep CITRIC ACID

Postby fargo on Sun Jul 03, 2011 9:08 pm

Hi All,

Just thought i would put this up as i have searched around and found this to be the best economical and efficeint way to remove rust from panels and parts.
Most of you may know this already but thought i would share as i did a search and minimal info came up.

Citric Acid Solution to remove rust from panels does an amazing job very little cost and made from citrus.
I can purchase 1kg of citric acid crystals (used in cooking) at a food store for $4.00 and diluted with 15 litres of water makes the solution (add more to make more solution)could probably buy it cheaper and bulk from a chemical supplier

Left over 24 hours does wonders the picture of the parts below have been left in longer around 2 days a very light wire brush then put into the solution removed then a scrub with a platsic brisstle brush and hosed off.

I know coke and alot of other soft drinks and substances have citric acid in them this was easier and cheaper.

After finished a light wire brush then there ya have it.

Any thoughts good or bad let me know!

Just to add and correct me if i am wrong the Molasses method is similar the fermet reacts and turns it into cirtic acid just takes longer from what i have read and seen.

malt vinigar from woolies or coles, $2.50 for four litres, also does the same job, you just need to make sure you wash everything really good in soapy water afterwards or it keeps eating away at the metal. check parts every 12 hours, these discs came up like this after 18 hours soaking in mault vinigar, when removed you just use tap water and a dishwashing brush, then repeat washing in soapy water.

Very interesting. Does this stuff only work by immersion? How would you go about doing large panels? The rear guards from my Wolseley have quite a bit of active rust on them and I'm thinking they will need something doing sooner rather than later.

Thanks for sharing a great idea!

I Think phosphoric acid? Hotrod andy Used on his surface rust, seemed to do the job.. Must admit i havent tried anything myself as yet.. but need to do so soon.. roof interior, front & rear guards :lol: :lol: :lol:
