Efflorescence is a white, powdery substance that can appear on pavers due to moisture dissolving salts and minerals within the pavers. To treat efflorescence, remove debris from the surface of the pavers and use a solution of equal parts white vinegar and water to scrub the affected area. Rinse the area thoroughly with clean water. If necessary, a stronger solution of muriatic acid and water can be used with caution. Prevent efflorescence by ensuring proper drainage and moisture control, such as installing a layer of gravel under the pavers and using a sealant on the surface.
