daver555 Posted April 16, 2009 Report Share Posted April 16, 2009 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 Link to comment Share on other sites More sharing options...

alexp5 Posted April 16, 2009 Report Share Posted April 16, 2009 Good stuff! I've used 'a popular brand of Cola' instead of WD40 before on rusted fasteners. It works. And tastes infinitely better. Link to comment Share on other sites More sharing options...

stretch Posted June 10, 2009 Report Share Posted June 10, 2009 saw this thread some time ago and tried it with an old, old, old, bicycle brake over the weekend. I did not have malt vinegar, so tried apple cider vinegar, the cheap processed, filtered, clear stuff. and it rocked, brake went from crap to looking brand-ass new. I let it soak for 4 days, but that was just me not getting back to it. I did the other brake last night, and will check today, im sure it will sparkle just like the other. i looked it up to see which vinegar is the most acidic, but have forgotten if malt is stronger or weaker than apple cider vinegar, hope to land some pickling strength stuff soon. was very impressed!

Frey Bentos Posted June 10, 2009 Report Share Posted June 10, 2009 Would this work on a bike rim? The wheels on my Gs are fucking shite. The lacquer is long gone and the Aluminum is badly coloured and basically covered in crap. Thinking it could be a way to lovely clean wheels again. Er, don't suppose it would do tyres any good either? Link to comment Share on other sites More sharing options...
DC98 Posted June 11, 2009 Report Share Posted June 11, 2009 Certainly made a good job of those drive shafts. What effect would it have on ali? Good point, anyone know if its is safe of ali. I'm thinking I might drop my carbs in some. Link to comment Share on other sites More sharing options...
Kayla Posted June 11, 2009 Report Share Posted June 11, 2009 Good point, anyone know if its is safe of ali. I'm thinking I might drop my carbs in some. You can soak carbs in a popular brand of cola to clean them so I'd guess* that vinegar, being a weaker acid, would be ok too. * I do reserve the right to be wrong though.

kens Posted March 3, 2010 Report Share Posted March 3, 2010 Vinegar/acetic acid, wine (or even fruit juice) will dissolve aluminium, so be careful not to leave things soaking too long1. Also, if you have recently removed the oxide layer by polishing, the bare aluminium will react in possibly unexpected ways, although if the oxide layer is intact the acid should not touch the metal. If there is aluminium powder or swarf present it could react violently to the acid, evolving hydrogen. So along with not charging your battery in a confined space, you should ventilate your vinegar parts washer. and rinse parts off before soaking them, just in case. Magnesium engine parts could also react spectacularly in some cases. My advice - 'test on a portion of the material which cannot be seen'. 1 - I may have worked somewhere a long time ago where someone may have lost an aluminium spanner. It may have been found at the bottom of a 40,000 litre tank of wine some weeks later, as nothing more than a skeleton of the original part. We may have hidden the evidence. Wine containing aluminium ions forms a haze which is difficult to remove, and consumers of aluminium may suffer mental health outcomes2 2 - Alzheimers. Allegedly. What?

Frey Bentos Posted March 3, 2010 Report Share Posted March 3, 2010 Patience dear prat. Patience. There's no point cleaning the sodding thing at the moment. The salt is still around and the wheel is under an inch of wax. @Kens. Thanks for the heads up. I wasn't going to leave it for too long. Not over night but as I have two sets of wheels for the bike. The winter one and a summer one in far better condition I feel it is okay to push the boundaries of science a bit. Yeah I know what you are thinking. What a guy. Willing to take one for the team. Whadda ya mean that's not what you were thinking? Link to comment Share on other sites More sharing options...
