## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works like magic!
  

*by C***. on Reviewed in the United Kingdom on 2 April 2024*

I have used this product for a number of years and I am still amazed how effective it is. My patio slabs look as if they were laid yesterday, the crazy paving is bright and clean, the block wall could have been erected last week, the algae, moss and lichen have disappeared from the garden walls and fences and the property walls appear to have just been painted.I use a garden sprayer and the solution is best applied to a dry and cool surface so that the former then remains moist for as long as possible. I do this once a year in springtime on a cool, clam and cloudy day or in the early evening. You don't want it to rain for about 6-8 hours or even a bit longer. That's all you have to do. Be patient and let the sun, rain and wind do their stuff over the coming days, weeks and months. Even the most stubborn types of lichen will eventually disappear. (Should an area be in constant shadow, it isn't quite so effective and you may have to repeat the application after a few weeks or use a stronger solution.) Overall, it makes life so much easier and works like magic!

Could not recommend this product enough. Sprayed my drive, patio, front and back fence. Looks like new again within days. Had some left over from last year. Worked just as well. Will get even better results after it has rained. Worth the price, very well packaged and really quick delivery. Thank you
