Efflorescence Remover+ is a non-acid chemical with the added advantage of neutralising the salts on and within the substrate, reducing the possibility of a re-occurrence of the white deposits. What is efflorescence?  The term is generally applied to any white deposit on paving, brickwork and cement. However, the white deposits can be one of many salt types, and different products are required to treat them. If the deposit is fluffy and can be brushed or washed off, it is likely to be sodium based. The correct product for this is Efflorescence Remover+. However, if the deposit on the surface is hard and doesn't dissolve with water or will not easily brush off, it is likely to be calcium-based. For this problem, use Mortar Stain & Calcium Remover. This removes the white deposits but cannot prevent the possibility of re-occurrence.Removes salt stains from brickwork Features: Organic formula dissolves and neutralises salts for long lasting results Prevents salt deposits returning Simply ap
