Does muriatic acid clean efflorescence?
A conventional chemical cleaner that has been used for removing efflorescence is muriatic acid in a mild solution, usually one part muriatic acid (hydrochloric acid, HC1) to 12 parts water. Several mild individual applications are better than one overpowering dose.
How long does it take for efflorescence to disappear?
Over time, efflorescence will eventually wear away or disappear, usually within 3-6 months, although it can take much longer depending on the circumstances.
How does vinegar remove efflorescence from concrete?

Is efflorescence acidic or alkaline?
A chemical analysis of efflorescent salts in the Southern California area (1) reveals that they are principally alkalies of Sodium Sulfates (Na3S04) and Potassium Sulfates (K2S04).
How do you remove white residue from concrete?
Buy an Acid-Based Efflorescence Cleaner The white residue on the surface of new concrete can be removed only with an acidic cleaner. Given enough time, acid rain can clean the majority of white concrete stains, but many homeowners do not wish to wait to remove the problem.

Does sealing stop efflorescence?
Sealing masonry surfaces The best protection against efflorescence and water damage is to use a penetrating sealer to make the surface entirely waterproof. The products we recommend using are a masonry sealer such as Resistain or Shower Plug.
