Outdoor and Building FAQs
Here are the answers to some of our most frequently asked questions about our Outdoor & Building products:
SCRUBB outdoor cleaners are formulated for specific exterior surfaces such as paving, decking, driveways and exterior tiles. Each product is designed to clean effectively while protecting the material it is intended for. Always check the product label to ensure it is suitable for the surface you are treating.
SCRUBB outdoor cleaning products are designed to tackle typical exterior contamination, including grime, ingrained soil, grease, leaf stains, bird droppings and organic deposits. Some specialist products also target algae, mould or green growth depending on the formulation.
Some SCRUBB cleaners are ready to use, while others are concentrates that should be diluted before application. Always follow the dilution instructions on the label to achieve the correct cleaning strength and best results.
Most SCRUBB outdoor cleaners can be applied using a watering can, low-pressure sprayer, brush, or pressure washer detergent tank depending on the product and cleaning method. After application, allow the product to work for the recommended time before rinsing or brushing as required.
Contact time varies by product and level of contamination. Many cleaners work within 15–30 minutes, while specialist treatments such as algae removers may require longer working times to fully eliminate biological growth. Always follow the instructions on the label for best results.
Light agitation with a stiff-bristled brush can help loosen stubborn grime and improve cleaning performance. However, some products are designed to work with minimal scrubbing, depending on the surface and level of contamination.
Yes. Surfaces and materials can vary, so it is recommended to test the product on a small, inconspicuous area first before treating the entire surface. This helps ensure compatibility and prevents unexpected results.
Avoid contact with ornamental plants, lawns, ponds and waterways. If accidental contact occurs, rinse the affected plants with clean water. Treated surfaces should be allowed to fully dry before allowing children or pets back onto the area.
Coverage varies depending on the product and surface condition, but a typical 5-litre container covers up to approximately 30m². Heavily contaminated surfaces may require additional product or repeat applications.
Store the product upright in its original container, in a cool, dry place away from direct sunlight and extreme temperatures. Always keep cleaning chemicals out of reach of children.
Yes. Many SCRUBB outdoor cleaning products can be applied using a pressure washer detergent tank or rinsed using a pressure washer after application.
SCRUBB Sandstone Paving Cleaner & Renovator is designed specifically for natural sandstone paving surfaces. It helps restore patios, paths and other sandstone areas by removing deeply ingrained grime and staining.
The formulation is designed to lift deeply ingrained grime, black spots and general staining that can build up on sandstone paving over time, helping restore the natural appearance of the surface.
No. The product has been developed to deep clean natural sandstone without eroding or etching the surface when used as directed. However, surfaces can vary so testing first is always recommended.
Remove loose debris from the surface and apply the cleaner neat using a sprayer or watering can. Saturate the paving and allow the product to work before rinsing thoroughly with water or pressure washing if required.
Allow the cleaner to work for at least 12 hours before rinsing. For heavily contaminated surfaces, longer contact times may be beneficial and the cleaner can be left to continue working for several days before rinsing.
For stubborn staining or heavy contamination, working the product into the surface with a stiff-bristled brush can help improve results before leaving it to work.
A 5-litre container provides coverage of up to approximately 30 m², depending on the condition of the paving and the level of contamination.
The cleaner is not suitable for use on coloured grouts or certain specialist jointing compounds. Care should also be taken to avoid overspray onto plants, fabrics, or delicate surfaces.
Avoid applying the cleaner during strong sunlight, hot weather, or when rain is expected within 12 hours, as this can affect performance.
Store the product upright in its original container, away from direct sunlight and extreme temperatures. Always keep the cleaner out of reach of children and pets.
SCRUBB Glass Clear is designed for windows, conservatories, glass balustrades and other exterior glass surfaces. It is ideal for both residential and commercial glass cleaning applications.
The professional-grade formula cuts through dirt, grease and everyday grime that build up on glass surfaces, helping restore clarity and visibility.
No. When used as directed, SCRUBB Glass Clear is formulated to leave a crystal-clear, streak-free finish, making it suitable for large glass areas where a professional result is required.
Dilute 100 ml of Glass Clear per 1 litre of clean water before use. This dilution provides the correct balance of cleaning power and streak-free performance.
Apply the diluted solution using a cloth, sponge, or window-cleaning applicator. After cleaning, remove excess liquid using a squeegee or wipe dry with a clean, lint-free cloth.
Yes. The formulation is suitable for both routine cleaning and deeper cleaning of heavily soiled glass surfaces, including larger exterior glass areas.
Yes. As glass surfaces and coatings can vary, it is recommended to test the cleaner on a small, inconspicuous area first before cleaning larger sections.
Store the product upright in its original container in a cool, dry place, away from direct sunlight and extreme temperatures. Always keep the product out of reach of children.
If the product comes into contact with eyes, rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do, continue rinsing and seek medical advice if irritation persists.
SCRUBB Porcelain Paving Cleaner is designed specifically for exterior porcelain tiles and paving slabs. It helps clean and maintain porcelain patios, pathways and outdoor tiled areas while preserving the surface finish.
The cleaner is formulated to lift grime, ingrained soil, grease, bird droppings and leaf stains commonly found on outdoor porcelain paving. It helps restore the appearance of the surface while maintaining it in good condition.
No. The formulation contains no bleach or acids, which can damage paving over time. It is designed to clean porcelain surfaces while maintaining their original slip-resistant properties.
No. This product is intended for general cleaning and maintenance of porcelain paving. Stains caused by algae or mould require a dedicated treatment designed specifically for biological growth.
For general cleaning, dilute 100 ml of cleaner per litre of water and apply evenly using a sprayer. Allow up to 15 minutes contact time, then agitate with a stiff brush and rinse thoroughly.
Yes. For tougher stains or heavily soiled areas, the product can be used undiluted as a spot treatment. Apply directly to the stain, work it in with a stiff brush, allow up to 15 minutes contact time, and then rinse thoroughly.
Yes. The cleaner can be applied using a hand sprayer or through a pressure washer, depending on the cleaning method preferred.
Yes. As paving materials and jointing compounds can vary, it is recommended to test the cleaner on a small, inconspicuous area first, especially where surfaces are jointed with resin-based or rapid-setting grouts.
No. The cleaner should not be allowed to dry on the surface. After the recommended contact time and agitation, rinse the area thoroughly with water.
Yes, absolutely – it’s ideal for removing concrete and cement build-up inside mixers.
No. These materials contain polymers and resins that EradiCRETE cannot dissolve.
