Efflorescence Remover, any tips or pointers?

[markwombat]

Hi all,

We moved into a new build 12 months ago. On the front of the house there are some white stains across the stonework, which I think has been caused by efflorescence(?)

Does anyone have any tips or suggested product to get rid of these unsightly stains?

Thanks in advance

Ibstock say:

In considering remedial treatments, efflorescence should preferably be allowed to
weather away naturally. Its removal can be accelerated by dry-brushing with a soft to
medium nylon/bristle brush.

A wire brush should not be used.
