You can buy it as brick acid, I believe, from DIY stores and

I'm planning to get some brick acid and pour it into my toilet. What
concentration would you recommend?

I'm not certain how concentrated it is and have not used it for a
toilet application. Since you probably don't want something too
vicious I would have thought diluting 5:1 would be a good start.
Add acid to water, of course, and you definitely do not want any
bleach around because copious amounts of chlorine gas would be
released. You can always increase the concentration of acid if
needed.



I've already tried emptying the trap and leaving it 24 hours with 2 litres
neat bleach filling the U-bend. It made it much cleaner, but there's still
loads of scale and general nastiness.
