EF Efflorescence Remover™ Specialty Clean

EF Efflorescence Remover™ is a specially formulated cleaner that acts quickly to dissolve efflorescence (white mineral deposits) that dulls pavers. These mineral deposits appear on the surface of the concrete as a noticeable sign of salt deposits migrating to the surface due to water movement. With our ready-to-use formula, you can quickly restore the original surface color on pavers, concrete, brick, and clay.

Remember to spot clean with an SRW Specialty Cleaner first, then clean the entire surface with PW Paver Wash™ or DW Dual Wash™ before sealing.

Why is cleaning before sealing important? Always clean before you seal for the best sealing results. SRW Products always recommends using PW Paver Wash™ or DW Dual Wash™ before sealing a project. Cleaning solutions pull dirt and debris out, opening up pores and leaving an ideal surface for the sealer to bond, while pressure washing alone drives dirt and debris deeper into the pores.

Efflorescence is a natural formation that may appear on any concrete or masonry product. It is actually the residue of soluble salts carried to the surface by moisture – a natural by-product of the chemical reaction between cement and water. Efflorescence does not affect the structural integrity and will dissipate over time. It is not indicative of a flawed product. If desired, it can be removed using EF Efflorescence Remover or PW Paver Wash.
No negative effects on the asphalt driveway should be expected. But it is possible that the surfactant could have a slight impact on the tar and dull it out. Test in a small discrete area if you are concerned.
EF Efflorescence cleaner is a mild acid used to remove the efflorescence currently visible. The cleaner alone will not prevent future blooms of efflorescence from occurring. To help prevent efflorescence blooms in the future, please consider the use of a penetrating sealer to waterproof the surface.
