Applying Efflorescence Cleaner
When you apply Single Clean to the efflorescence it should bubble up similar to shaving cream. Depending on the consistency of the efflorescence will determine how easy it is to remove the bothersome material. Once applied, you can simply power wash or scrub with a bristle brush and then rinse the surface to make sure it's clean. If there are difficult deposits that may require additional application then go ahead and repeat the process. Once cleaned of the efflorescence, seal with the appropriate sealer, in this case, retreat.
