## Questions & Answers

**Q: can this be sprayed on a tarmac drive without discolouring or damage to the surface**
A: I sprayed this onto tarmac, bare wood, painted wood, and a painted external wall and there was no discolouration at all. Very pleased with how well it worked.

**Q: Is it ok yo use near plants?**
A: My decking was full of plants when I used it and they all remained perfectly healthy. I did the decking in two sections so I moved all the plants to one side, sprayed, let it dry and then did the other side. It dries very quickly. It is brilliant stuff. Over a year later I have no algae on my decking.

**Q: Do you have to hose it down a day or so after use? i’ve got cobbled stone driveway and it’s gone green:( is the ration 1/4 litres? ? tia**
A: No need to hose down, just spray and walk away! Never used it this time of year. I use it end of winter early spring and it usually lasts throughout the summer. Brilliant stuff! I use 1-3 parts water. Hope this helps

**Q: Will this kill grass as my path is bordered by my lawn.**
A: It doesn't seem to have affected our lawn and in fact not a lot of liquid is involved. If you're worried, you could always lay a tarpaulin on the edge of the lawn near your paving stones. I've used it twice now and it definitely seems to work.

### ⭐⭐⭐⭐⭐ Magic
*by N***Y on 17 April 2025*

### ⭐⭐⭐⭐ Works well over time

### ⭐⭐⭐⭐⭐ Top notch product.
*by P***3 on 19 October 2017*

I've been paying twice the price of this product for 'Wet n Forget' which i thought was the bees knees and the best product on the market. It was only when my local Costco didn't have it in stock that I came across this product online and after reading excellent reviews decided to give it a go. It does exactly the same job, if not more, than 'Wet n Forget'. So in future I'll be saving money and using Pro-Clean. I have approximately 100 square meters of INDIAN stone around my bungalow and the surrounding trees and vegetation quickly turns it green in large areas. In the winter it goes slimy and slippery but Pro-clean brings it all up like new with no effort. Just mix it 5 parts water 1 part Pro-clean and spray onto the flags and walk away. In just a few hours the algae has gone. I use it also on my fencing, shed, conservatory roof and pvc furniture. In fact anything outside that gets affected by algae. It keeps working in the elements for months. I use it in the Autumn and Spring for great results. Try it and you won't be disappointed.
