A water jet
A water jet with high pressure is mostly used to remove the salt from the bricks. Pressurized water will dissolve the salt and wash it away. However, care must be taken to completely blow dry the water if you don’t want it back.
Your next option is to brush the powdery substance with the help of a stiff brush. For better results rinse the concrete with clean water and let it dry completely.
Mix acid with water and prepare a dilute solution. Apply the mixture and leave it untouched for about 15 minutes. Rinse the application with water. Make sure to moisten the surface before spraying the acid solution. HCl (hydrochloric acid) and H3PO4 (Phosphoric acid) are usually used for the same. Be very careful while working with any kinds of acids.
