Sure KIean® Ferrous Stain Remover is a specialty masonry cleaning product that effectively removes iron, manganese, vanadium, straw stains, acid burns and other metallic discolorations from brick, stone, and masonry surfaces.
Many staining conditions are created by excessive moisture in the walls. To avoid this, protect open wall cavities from rainwater during construction and correct any structural problems that allow water to enter the walls.
New masonry cleans most effectively if done within 14 to 28 days after installation. Allowing excess mortar and grout to remain for a longer time results in more difficult cleandown and may cause more severe metallic staining.
- Removes tough metallic stains quickly and easily
- Water rinsable
