I use 77% sulphuric acid diluted at 4-1, Works absolutely first class, but you have to be careful when adding the ACID to the water, NEVER add water to the acid.My eldest son uses it in his crop desiccation business always has at least 800 gallons on stock. Leave stubborn deposits over night then rinse well and a quick wire brushing metal comes up almost like new.
Also removes mill scale a treat, just dissolves it then wire brush off.

Phosphoric acid is also a common ingredient in these products. so you could use a cola!!
Basically they are just mild acids.

have you thought of the washing soda electrolysis method?

BTW, I also use phosphoric acid (10% solution in water) to stabilise the steel cleaned by the citric soak.

Where do you get the phosphoric acid from?

You can also get 40% phosphoric acid from ebay, Just over £20 odd quid for 5L which when diluted to 10% will last ages!

Used as a cleaning solution etc. And FAR cheaper than buying little bottles of Jenolite solution- which again is an expensive way of buying the same stuff.

Or Countrywides stores, sold as milkstone remover.

Yes, very true- it is sold as Milkstone remover. I asked for that but not being in a milk producing area- I can't get it locally in this part of kent.

Maybe worth making a soda electrolysis bath too, very cheap to do and also very effective, I use one all the time to remove rust. Done some part in my blog
