We were told a diluted CLR solution would work. We tried this and it was a lot of work to scrub the surface clean of the residue and you have to be sure to rinse immediately because technically CLR is not for painted surfaces.
You can remove efflorescence relatively easily with high water pressure (spray) or with acids such as muratic acid. Products such as CLR or Lime-Away can work too if used with water and a brush... These will keep moisture from seeping through the wall and evaoporating, leaving behind efflorescence.

Once the water source is eliminated, most efflorescence (also called Calcium Carbonate or limestone) can be removed with abrasive techniques. Dry brushing, light water blasting or light sandblasting followed by flushing with clean water. In large areas, rotary scrubbers with scrubbing pads may also be used.
First, for very mild cases of efflorescence, try a 50/50 mix of white vinegar and water. Using a scrub brush, spot treat and scrub affected areas with the vinegar mix. The acidity in the vinegar helps remove the efflorescence and calcium deposits by breaking down mineral crystals.
A stiff scrubbing brush and a dry brushing technique will remove the efflorescence. Muriatic acid can be used for efflorescence removal, but it poses risks such as discolouration and potential surface damage. Consider safer commercial solutions.
Calcium lime rust remover (CLR): CLR is a popular choice for removing calcium buildup. It's a powerful cleaner that can dissolve mineral deposits, including calcium, lime, and rust.
Clear water repellents, silicone and acrylic coatings also may help you remove efflorescence as well. The coating will absorb water across a masonry surface and prevent efflorescence from recurring. Plus, the combination of warm water and white wine vinegar has been shown to eliminate efflorescence.

If CLR Grease & Oil Remover is left on a surface for too long it begins to dry and can be very difficult to remove.
Muriatic acid is the standard way to remove it—muriatic acid basically being diluted hydrochloric acid. There are other efflorescence cleaners out there that can provide you with similar results, but they may be costly and perhaps not readily available, while muriatic acid more than likely will be.
Apply directly to the stain with a brush, cloth or sponge. After 2 minutes rinse promptly with cold water. Never leave Calcium, Lime and Rust Remover on an area for longer than two minutes.
