Kawasakifreak Posted March 10, 2010 Report Share Posted March 10, 2010 Seems to work rather well! http://www.cookhaus.co.uk/vinegar/index.htm Whats happening here is that vinegar is between 5-15% acetic acid a mild organic acid compare to mineral acids like hydrochrloric, phopshoric etc. What you are doing is gently etching those parts. Which is fine and works well on sensitive items. For rugged items you could upgrade a little, coke is stronger, I think it is similar strengh acid but is phosphoric, ouch. Bleach is peroxide which will have indetermiate results. If you have organic residues it might lift them off. Be careful on aluminium as it forms an oxide layer that seals it. You might try caustic and buffing. A milder approach on steel is the reverse, that is use caustic soda a strong base (NaOH), be careful though as both strong acids and bases burn you. NaOH by nature does not etch which is a good thing as once metal is etched off you cant put it back Anyone know how this etching process affects screw threads pls ?

kwakap Posted March 12, 2010 Report Share Posted March 12, 2010 Not sure if this helps but I noticed Caustic soda mentioned, it will eat paint so be careful, and as it has a high pH it will dissolve aluminium. oh and it has a real go at body parts too.....

Instant Gymnast Posted March 12, 2010 Report Share Posted March 12, 2010 I put my RGV 250 barrels, power valves, heads and PV covers in a bath of vinegar and after 36 hrs it had marked the cylinder plating. They needed doing anyway, but I feel I should point this out to all other forum members. It did do a lovely job on all the c**p in the coolant galleries and saved me a job with a wire brush.

Devon Posted March 25, 2010 Report Share Posted March 25, 2010 I'm about to do this with coke on a rusted exhaust manifold Link to comment Share on other sites More sharing options...
Devon Posted March 27, 2010 Report Share Posted March 27, 2010 right, after a few days under soak the coke had done an excellent job, I finally got the bolts off that exhaust manifold and that can now be sent off to be sand blasted with the rest of the stuff. I highly reccomend this procedure and can confirm that it does not damage aluminium in anyway as all my barrels are aluminium. Link to comment Share on other sites More sharing options...

kwakap Posted April 17, 2010 Report Share Posted April 17, 2010 Carrying on from this and maybe not as cheap.... I had to pick up some caustic for a steam boiler from one of our chemical suppliers Performance Chemicals in Erith Kent, the guy there (didin't get his name) was really chatty and helpful, he sells a fair amount of cleaners (acid based I think) used specifically for aluminium, they seem happy to do low volumes too. http://www.performance-chemicals.net/ I have not spoken to him about this but hey..

kaighn80 Posted November 19, 2010 Report Share Posted November 19, 2010 tried the vinegar remedy for removing rust but i didn't want to ruin anything i wanted to keep so i dug out some old drill bits, left them for 24hrs and scrubbed with a toothbrush and the rust came straight off! forgot to oil them though and by the next day they were red rusty again.
