Product Use Instructions
For the removal of stains on concrete and brick, use R&S Remover (typically 1 part water: 2 parts R&S Remover but can be used in a 1:1 up to 1:4 dilution depending on the severity of the stain). First, wet the surface and apply R&S Remover to the damp surface by spray, brushing, or broom on the affected area and to the entire section of concrete to create an even finish. Apply more copiously to the affected area than unaffected areas. Allow the product to dwell as the surface dries before rinsing with a pressure washer. For more severe staining, repeat in the affected area as needed. Very deep rust stains may only be visible when wet, so allow the concrete to dry again before making a final assessment. Note: When cleaning concrete or pavers, it is best to pressure wash first and/or clean with World’s Best Detergent and rinse thoroughly with a pressure washer. This can make it easier for R&S Remover to penetrate and remove the stains faster.
For removals on ‘non-porous/non-mineral’ surfaces such as painted walls, stucco, or vinyl, first rinse the surface with water and apply R&S solution to a damp (not dripping wet) surface. Typically diluted R&S at least 2:1 (depending on the severity of the stain). Do not let the product dry and rinse thoroughly when the stain disappears.
Coverage
WARNING: Before commencing any large-scale use, always test first in a smaller area. This product contains oxalic acid which will form water-soluble salts as it reacts with iron oxide. Rinse thoroughly after it has finished working. Some agitation with a brush may be helpful.
World’s Best Rust & Stain Remover will brighten concrete so it is best to spray on lightly from control joint to joint rather than just in the affected area only.
