Just read some reviews on the above where a chap restored some car brake discs complete with photos - do you have any idea what the main active ingredient is?
I know back in the 1960's our paint sprayers used something similar on new body panels that had some flash rust from long term storage.

James, I've not tried this but heard good results. What dilution do you use?

Normally 100g per litre of warm/hot water. So 1kg makes 20 litres of de-rusting solution, working out at about £1 per litre (compared to circa £6/liter for evaporust).

Mr Google seems to say the BH Deox C is Citric Acid based.
Whilst having a shave an hour or so ago I had an old memory surface from when I worked in the Analytical Process Lab at Associated Octel back in 1967 as part of my "thick sandwich degree course".
One of my monthly jobs was to dilute some of the highly concentrated acid with water to make stock reagents that were used daily in the Lab.
I was actually quite nervous of the process as I had to add a precise volume of the acid to the water as the temperature of the water rose it was important not to rush the process to avoid acid spitting. The strong acid was contained in large glass vessels iirc with a steel wire support cage packed with some sort of brown wadding.
Due to the passage of time I can't remember what the acid was - not done in a fume cupboard due to the size of the flasks - just safety specs, face mask and rubber type gauntlets plus a rubber type apron.
Afterwards I would always wash my face and arms feeling itchy for the next hour - even my scalp demanded scratching.

I cleaned the interior of a tank like that, but then it turned black! :o

Thanks, I just read about it. Alas, I wouldn't want to keep it in the house too toxic, I have some COPD and I avoid risk as suggested in my original post, if in an exaggerated way! :o
