How Efflorescence Works

  1. Simple washing can sometimes remove efflorescence. Scrub with a stiff brush and mild detergent or plain water.
  2. Power washing also can be effective in removing surface deposits.
  3. Sand blasting is effective, but should be used with care.
  4. Chemical cleaning might be needed for some cases of efflorescence.

Subsequently, question is, will CLR remove efflorescence? 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.

Regarding this, does efflorescence go away?

In many cases, efflorescence will disappear on its own over time (usually after the first year of a paver or retaining wall installation). Efflorescence can also be removed with special cleaners like the Gator Efflorescence Cleaner. On average, you should wait about 60 days before applying an efflorescence cleaner.

Is efflorescence a sign of damp?
