By kathleen hughes

this cleaner is excellent, it has cleaned up our 40 year old flagstones amazingly well. the flags were so soiled i appled it neat to the dampend flags and left it on for 3 hours, some of the blackspot needed 2 applications but the results were great. this stuff is strong, wear protection as advised, don't waste your money on patio cleaner from the garden centre, this is the stuff you need.

Product Description

Smartseal Xtreme Multi Surface Cleaner is a professional grade multi-surface cleaner specially formulated for the quick removal of black lichen, mould, mildew, green algae and general surface staining from most external hard surfaces.

Suitable for use on:

  • Concrete & Block Paved Driveways
  • Natural Stone Patios including Sandstone, Limestone, Granite & Slate
  • Wooden Decking & Garden Furniture
  • Composite Decking
  • Roof Tiles
  • Brickwork & Masonry
  • Flagstones

It is used widely by many commercial cleaning companies to clean external hard surfaces without the need for intensive pressure washing. It's an easy to apply, fast-acting formulation, that leaves outstanding results and makes hard surface cleaning easier than ever before. This powerful alkaline cleaner can be used on concrete and most types of natural stone without risk of damage to the surface. 

In most cases, a dilution ratio of 1:1 is sufficient to get outstanding results but in cases of heavier surface contamination, the product can be applied neat.

Product FAQs

Q: I have a sheet metal powder coated roof to clean. Covered in green and black algae appropriately 500m2 what would you recommend I use and the suggestions on the application would be appreciated. Many thanks Phil

Phil Dale

A: The Xtreme Multi-Surface could discolour the metal on the roof. You would be safer to use our Green Clear Pro, as that will not harm your roof and do a great job in removing green growth.

Response from Alex

Q: Do you have a product suitable for cleaning KREND render?

Martin

A: The Xtreme Multi-Surface Cleaner is formulated to be used on K-Rend, without causing any harm to the surface. It will do a fantastic job on cleaning algae, blackspot, lichen and general dirt and grime.
