Thanks John, I just wanted to double check, it’s really not worth using the acid? If not, I’ll get rid of it at the tip because I only bought it for the wall.
i live in a hard water area and we get a lot of lime bloom on new walls, worst in the first dry spring when it is drying out, and worse if the wall has got very wet during build. Then it weathers away.
sometimes there is a bit more in the second spring, once the wet weather is mostly over.
IME brick acid is not needed, but opinions may vary.
the acid is needed for cement mortar splashes and smears, which are more durable than lime bloom.

I'm naughty and lazy. I left the top of my extension cavity open to the elements over the winter and have terrible effervescence. As a trial I had a very quick go with the brick acid, I think you can see that it does work:
