INSTRUCTIONS FOR USE

For Removal of Stains from Concrete & Brick: Wet down the surface with water. Then dilute as needed and apply R&S Remover by spray, brush or broom to the affected area and to the entire section to create an even finish

Comes in 1 gallon and 5 gallon containers.

Apply more copiously to the affected area. Allow the product to dwell as the surface dries before rinsing with a pressure washer. For more severe staining, repeat on the affected area. 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 Concentrate and rinse thoroughly with a pressure washer. This can make it easier for R&S Remover to penetrate and remove the stains faster

For Removal of Stains from ‘Non-porous/ Non-mineral’ Surfaces such as Painted Walls, Stucco or Vinyl: First rinse the surface with water and apply R&S Remover to a damp (not dripping wet) surface. Do not let the product dry, and rinse thoroughly when the stain disappears.

CAUTION: Before commencing any large-scale use, always test first in a small inconspicuous area. This product is a highly effective, fast acting acidic remover, and is capable of discoloration or damage on some surfaces.

Please take care to avoid applying to anodized aluminum or other metallic finishes.

TIPS FOR ACHIEVING EXEMPLARY RESULTS

TIP 1: When cleaning concrete or pavers, it is best to pressure wash first and/or clean with World’s Best Detergent Concentrate and rinse thoroughly with a pressure washer. This can make it easier for R&S Remover to penetrate and remove the stains faster.

TIP 2: 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.

TIP 3: This product contains oxalic acid which will form water soluble salts as it reacts with iron oxide. Rinse thoroughly after it has finished working.

TIP 4: Some agitation with a brush may be helpful. R&S will brighten concrete so it is best to spray on lightly from control joint to joint rather than just in affected area only.

SAFETY ISSUES: Causes serious eye damage. Keep only in original container. Do not breathe mist, spray, vapors. Wash exposed skin thoroughly after handling. Wear eye protection/face protection/protective clothing/protective gloves. Refer to SDS for safety information.

LIMITATIONS: Due to the superior cleaning power of World’s Best Rust & Stain Remover it is advisable to check for ‘over cleaning’ in some areas before commencing large scale use.

ENVIRONMENTAL CARE: World’s Best Rust & Stain Remover is biodegradable. If necessary, water can be collected using a wet vac and disposed of safely. We believe nothing other than rainwater should enter our precious storm water systems.

CAUTION: Before commencing any large scale use, always test first in a small inconspicuous area. Avoid applying to anodized aluminum or other metallic finishes. 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.

• Vinyl siding

Unlike harsh acids, it restores surfaces without damaging them when used properly.

Will it damage or etch concrete like muriatic acid?

No—this is one of the biggest advantages.
