Oxalic Acid

Hi All.

I have read somwhere about Oxalic acid baths? Been on the old fleabay and they sell the stuff quite reasonably but is it what i am after?

http://cgi.ebay.co.uk/Oxalic-Acid-400g-Tub-ethanedioic-acid-Stain-removing_W0QQitemZ290209856092QQihZ019QQcategoryZ104233QQrdZ1QQssPageNameZWD4VQQcmdZViewItem?_trksid=p1728.m124

Basicly i have an old DB frame that has strange 'liquid' marks on it and i have tried autosol etc but nothing seems to be shifting it. Is it possible to get this stuff off the bay and get a garden hand held spray bottle and spray it on and give it a rub without actually having to bathe the whole frame. (Dont think the wife would let me stick it in the bath)

Any help / advice would be appreciated.

Cheers
Steve

You really need to soak it for a couple of days. I'm not sure it will get the marks off you mention,but is worth ago. as the chrome does shine up nice.  :daumenhoch:

I use mine in an old wheelbarrow  :daumenhoch:

Munners did me a quite large favour and let my RSR frame and forks soak in his oxalic bath for a few days and it came out gleaming.  It will highlight any defects in the chrome like scratches or chips in the chrome and won't necessarily remove the marks, it will remove almost all traces of rust though.  Definitely worth doing as it gives the chrome a good clean removing years of grime  :daumenhoch:.

munners:
cheers mart. ;)

would love to see a pic of it now. ;) :shocked:

  Forget the bay mate you need more than what they are offering.

 At least 5kgs is required and it needs to sit for at least a couple of days, these are the best dealers of the stuff i have found and the cheapest, also offers a 24hr postal service.
