Everbuild Salt Away Sprayable 5 Litre EVBSALT5 Salt-Away is a biodegradable and safe formula that removes salt and unsightly white efflorescence from bricks, stone and concrete. Efflorescense is commonly caused by soluble salts within the building materials, or when salts are transfered into building materials by water. At the surface of the building material the water containing these dissolved salts evaporates leaving behind unsightly white deposits which if left untreated can cause corrosive damage to many building surfaces. 5 Litre Container EVBSALT5
