SmartSeal Patio Cleaner Xtreme - 5L - Powerful Black Spot Remover Patio Cleaner & Rapid Mould Lichen and Algae Remover for Cleaning Stone Paving, Concrete, Sandstone, Porcelain, Slate & Granite

Why we love it
  • Effective against numerous fungus types.
  • Enables efficient, fast cleaning.
  • Suitable for various surfaces.
Main Highlights
  • Powerful Patio Cleaning Solution: Patio Cleaner Xtreme is used for cleaning stone patios fast. The powerful heavy duty patio cleaner is often used as a patio black spot remover & lichen remover to rapidly clean and transform the look of patios covered in dirt, algae, lichen and grime. The multi-surface patio cleaner will quickly clean paving slabs made from concrete, slate, granite, limestone, porcelain and sandstone.
  • Multi-Purpose Cleaner for Patios: The versatile black spot patio cleaner is also classified as an algae remover & lichen remover. Apart from cleaning patios, it is also used as a decking cleaner or, more often these days, as a composite decking cleaner. Depending on what your patio is made of, it will also work just as effectively as a porcelain patio cleaner, block paving cleaner or a general paving slab cleaner.
  • Fast-Acting & Easy To Use: Patio Cleaner Xtreme is easy to apply by watering can or sprayer and usually diluted 1:1 with water, but can be used neat for heavily soiled patios. It is the ultimate green algae remover & black spot patio cleaner that ensures a fast & effective patio cleaning process. 5 Litres will clean approximately 40m2. A second application of the outdoor surface cleaner may be required for very dirty patios.
  • The Ultimate Patio Cleaner: If you have a patio that looks like it needs a good clean, Patio Cleaner Xtreme is the go-to patio cleaning solution that can make an old, grubby patio look like new in no time at all. Furthermore, it is just as effective as a concrete cleaner for concrete paving slabs or a natural stone cleaner for sandstone, limestone, slate & travertine patios.
  • Outstanding Cleaning Results: Patio Cleaner Xtreme is very effective at removing green algae, black spot lichen, mildew, fungi, mould, and organic stains without damaging your patio. The powerful limestone cleaner & slate cleaner contains a unique blend of cleaning surfactants, specially formulated as a patio cleaning alternative to Sodium Hypochlorite solutions. It will also inhibit further growth and spread of lichens, algae & other fungal growth.
