Powerful cleaning agent for eliminating organic green contaminations from roofs, tarmac and hard outdoor surfaces

Green Remover Concentrate will effectively remove green organic contaminations from roofs, tarmac, concrete, stone, block pavers and hard-surfaced driveways. This product is a powerful cleaning fluid for treating external vertical and horizontal surfaces, removing problematic organic growth. Green Remover Concentrate can be applied to any roof, driveway, patio or other external hard surfaces where you wish to quickly treat green growth, algae, moulds & other organic contaminations.

Spray on and leave the cleaner to eliminate green organic contaminations without agitation

Simply spray the product on and walk away, it could not be easier. This powerful cleaning agent has a non-acidic formula so it will not damage acid-sensitive surfaces like limestones or concrete. It is highly effective at removing green contaminants and is suitable for use as a general one-step patio cleaner. This product removes the need to regularly pressure wash green organic contaminations, algae & mould from your patio or pavers. For the removal of heavier build-ups of green growth on roof tiles, spray over the area and allow the solution to soak in. This will start to break down any growth over the following days/weeks/months. Follow the same procedure for the removal of green growth & other organic contaminants on tarmac driveways. For best effect saturate the surface so the solution is fully absorbed into the contamination you are trying to remove. Green Remover Concentrate is to be diluted 1:5 with clean water, you do not need to apply this product neat. (It can also be used at a dilution rate of 1:3 when treating heavily contaminated surfaces). 5 litres of Green Remover Concentrate will produce 30 litres of cleaning fluid (when diluted at 1:5). This means you can cover a surface area of approximately 100m2 – 120m2 with a single 5-litre container! Green Remover Concentrate is one of the most economical and effective green organic growth removers on the market. Apply Green Remover Concentrate using a low-pressure sprayer. Saturate the surface making sure not to exceed 5m2 per litre of diluted cleaning fluid. Please allow the product to dry on/into the surface to remove green organic growths, algae & moulds. This cleaning fluid can be used as a general one-step, no-rinse patio cleaner. It can also be used as a quick periodic cleaning solution to treat surfaces which have been sealed with one of our sealers. It will also inhibit the reappearance of green growth, algae & lichens when applied once or twice per year. Available in 5 litre, 10 litre & 20 litre containers with free economy shipping and express delivery shipping options.

  • How long does Green Remover Concentrate take to work?

    Once the surface has been treated, green matter, algae & slimes will die off over the next few days & weeks. Larger clumps of growth will take longer but will eventually perish.
