Review: TOP QUALITY PRODUCT - This is a top quality product that I have used frequently. Please read the instructions carefully. A few things to mention; the normal ratio of 1lt of product to 4lt of water makes 5ltrs. This is great for smooth flat non absorbent or vertical surfaces (Fence panels) For flat paving slabs,, concrete, stone, plain or decorative /brick weave/composite surfaces; I would recommend 1lt product to 3lts water, with two sprays about 2 weeks apart Make sure that all surfaces are dry & it is vital that the surface remains rain free for a minimum of 6 hours after treating. BUT, do not treat with a surface temperature below 8c or above 20c. Use the opened "undiluted product" promptly as it will not keep in the long term The instructions are clear and understandable on the label The instructions say to drench surfaces, I have only sprayed from a 5lt "hand pumped sprayer & to successfully "drench" such as brick weave & semi porous horizontal surfaces please work on a coverage of about 25/28 square meters per 5lt of sprayed mixture Don't be tempted after spraying (including a second spray) to pressure wash thinking the product is not working, WAIT ! This is a slow acting long lasting treatment - natural wind and rain is enough help (the manufacturer does say that a soft brushing after a while or at most a normal rinsing from a hose nozzle after a period of time is ok, but I have not done that!) Because once opened the undiluted product looses effectiveness as the label says I think the buying in 5lt flasks is best to save on waste. This product does not contain bleach. Do take sensible precautions when spraying, gloves & a face mask as with any sprayed product
Review: Easy to apply - I use on drive and patio. Works well but not permanent and have to use twice anually.

## Features

- Effective Mould, Lichen & Algae Remover: Green Clear is a powerful biocide specially formulated for use as a roof tile cleaner, patio algae remover, and stone cleaner. The multi-purpose no rinse patio cleaner is also frequently used as a green algae remover for sheds, fences, caravans, boats, as well as upvc windows and conservatories.
- No Scrubbing or Rinsing Required: Green Clear is an easy-to-apply spray and leave patio cleaner that delivers effective cleaning results without the need for pressure washing or surface scrubbing. It is also an excellent decking cleaner and composite decking cleaner that can be used now and again to prevent them from getting slippery.
- Excellent Coverage: One 5L bottle is enough to treat up to 125m², making it a very cost-effective solution for cleaning large outdoor surfaces such as tennis courts or car parks. Usually diluted before use, it can be used undiluted on areas with lots of green growth to work well as a paving slab cleaner, block paving cleaner or roof cleaner.
- Easy to Apply & DIY Friendly: Green Clear is a green algae remover that can be easily applied using a watering can or pump sprayer. It is best described as a spray and walk away cleaner that quickly kills lichens and green algae on exterior surfaces. After applying the spray cleaner, any green growth will start to die off within a few days.
- Multi-Surface Cleaner: There are many uses for this powerful outdoor cleaner, so no need to look for a different product for every surface you need to clean. It can be used as a tarmac cleaner, fence cleaner, wood cleaner, wall cleaner, render cleaner, as well as a brick cleaner, to name but a few. It is a one-product fits all outdoor cleaning solution.

### ⭐⭐⭐⭐⭐ It k*lled the lot
*by M***N on 26 May 2024*

I've been very ill, in and out of hospital and what have you, which has had a very bad effect on my MS. This means that things have overgrown and been neglected at the back of the house for nearly 2 years. There was an impressive thick, green carpet of moss, beloved by all God's creatures, except for me. I shifted everything over to one side of the yarden and used this on the other. It offed the lot and I just finished off brushing up the dead moss yesterday, so I'm waiting for some consistent dry weather to do the other side. Brilliant product! Would heartily recommend. Thank you very much!
