Do I have Efflorescence on my walls? All manner of questions and solutions to problems and issues surrounding the subject of brickwork, blockwork and stonework

[wanoennogs]

So far I have tried a vinegar and water solution. I have also tried a chemical solution called salt away. I have used a jetwash afterward.

What I have tried has failed to remove it.

Do I have Efflorescence on my walls? If I do how do I get rid of it?

Here is a link to a photo of one of my walls

Hi wanoennogs,
It looks like water is getting into the wall above the line of salts, this water is then permeating down to whatever the line of header bricks is laid on (presumably an impervious cement mortar) then coming to the surface carrying salts with it.
You could try cleaning it off with brick acid but it will come back.
