It's calcified efflorescence.  Use Heavy Duty Acidic Cleaner combined with Phosphoric Acid.  It will deffo take a few applications but coupled with a Hand Held Rotary fitted with an SIC Brush will make fairly light work of it.  Problem is that once that area is done it will show the rest of it up

Without getting technical.  Just a spray with 50% HCL should disolve it and the just rinse it off.

He registered on here 4 Months ago and the link refers to something in Australia so I wouldn't worry about it.  There is no magic formula for getting rid of calcified efflorescence.  You need to firstly remove the source then remove the efflorescence using a combination of Eff-Ex, Phosphoric Acid and a brush depending on how hard it is
