Hotdog/Oldschoolace,
                                 How much do i use, how long do i leave it for and is it easy to get your hands on it ?
                                                                                                                                                                   Cheers

I have found chrome items are fine - the rust will turn a grey greenish powder and need washing off

but if a item has loose chrome or open metal it will need shorter time in as it affects the metal and turns it all greenish and it will need a polish to get off

time in can be a hour to 6 hours - any more and it tends to mess it up a bit and go past what you need

amount ? I have a plastic tray about 12"x45" and 3" deep - kids and pets out the way of it all - gloves on - i just use about 2-3 table spoons of AO after i have put hot water in - stir and then add parts - always wash parts after in hot soapy water - dispose of the solution in a safe and clean way

but amount of water to solution and volume of tub used can very - it's all try and try again and again this is just my way - wait for others to say how they do it and then put it all together and see what you come up with  ;)


If some parts don't come up as you want - then it maybe that you will have to turn to a polishing mop on a bench grinder or hand polishing

on clean up old parts you will have to try more than one method - so methods work well - some will only do certain parts and some can mess up what you want clean and nice - measure twice and cut once - soft before hard - and test first  ;)

cheers B  ;)

Nice One mate, I got a general idea. I suppose it's trial and error to some extent. Just need to find somewhere local to get some Oxalic/Citric acid.
Thanks for your time, your effort and your patience.   :daumenhoch:
