Removing ''hard water" stains from brick work.
 

We live in an area with especially hard water and had an issue with a
toilet overflow- fixed some time back. However, it left some stains on
the wall. I had hoped they would fade but they hadn't. Scrubbing and
power washing hasn't helped.

Does anyone have any suggestions, please?
