mikevernontalktalk.net Posted July 1, 2005 Share Posted July 1, 2005 Where can I get hold of some phosphoric acid? A chemist friend gave me some years ago and it's finally running out. It's the best thing I've found for rust treatment and for surface preparation of bare steel prior to painting. Link to comment Share on other sites More sharing options...

DohNut Posted July 1, 2005 Share Posted July 1, 2005 Sweet talk a school chemistry technician I seem to remember buying a 2-pack product from Halfruads , acid to de-rust then an inhibitor etc. I think I sent the stuff off to get profesionally painted in the end.

Wight Skipper Posted July 1, 2005 Share Posted July 1, 2005 'Supa Glaze' from Arrow Chemicals is 18% Phosphoric Acid and is great. It is designed for bogs but will do most things. Link to comment Share on other sites More sharing options...

Nigel Riches Posted July 3, 2005 Share Posted July 3, 2005 Food grade phosphoric acid (85%) should be available from any reputable chemical supply company, whether they will allow you to buy it would be a different matter, a look through the Yellow pages may point you in the right direction. How do I know this? I use it, diluted, to remove Calcium Oxalate (beer stone) from my brewing vessels. 1982. 5 speed, clamshells. B.R.G / Ali. The True Colours.

Chris W Posted July 3, 2005 Share Posted July 3, 2005 Coke definitely has phosphoric acid as a constituent. Experiment with an old copper coin left overnight in Coke. Chris 2003 1.8K SV 140hp see it here Link to comment Share on other sites More sharing options...
