Then I acquired from joy of experimenting even a bottle of this substance; diluted with water and spread with a Gardena pump sprayer to the cleaned plates. Of course, nothing has changed because - they were already clean. And now, after nearly four months, they are still spotlessly clean!
It can mean the difference very easily see the places where I was too lazy, add spray the agent - there the stones look just like before the treatment: dirty. So it works!
In the driveway I have between a patch grid and over a 2 cm range grass. Of course, the stones are now no longer light gray but black and moss-covered. In manachen years, I have taken the trouble to edit each paving stone with a high pressure cleaner. Sauerhei disgusting and senseless work, because after a few weeks / months sees it again exactly as before.
So I draufgesprüht the Dethatcher just look at a few stones. Just a wide array of treats - the rest not because I was too lazy and only once wanted to see how it works.
Well - not at all. The grass suffers slightly lower; but recovers. Even after a long time I could not detect any effect and have it once forgotten. After three months, I noticed that I had a white stripe in the driveway. The stones that I had sprayed the moss remover were pretty clean and bright. After I had treated only a "strip" in the driveway, you could see the difference very well.
Conclusion: the agent need weeks or months to clean up these stones. Somehow penetrates the means and the rain does the rest. But slowly. But the effect seems to last very long. As it stands, I need my high pressure washer to stop using.
Well - how many stars should I give it?
Five because it does what it should.
Two, because it takes a bloody long time until it makes an impact.
Four, because the protection apparently persists for a long time.
Recommended approach: even high-pressure cleaner; then that means it and rest.
