"It 100% works !"

Have been using black spot system for 2 seasons now
Every time I use the preventer I can’t believe how it brings back the warmth of the stone …as well as removing all the stuff that builds up over the winter period ….I love it !
It is truly brilliant !

"Amazing results"

Amazing results, especially on older stone.

Found this company to be exceptional. We wanted their professional team to renew our travertine patio areas and associated walls as their comprehensive guarantee was attractive and it was a very large area to cover.

The two gentlemen that arrived were polite, friendly and completed the work with care and enthusiasm. The results were outstanding and the old stone which was black in most places was restored to it's first laid glory. They took care to protect any plants overhanging the walls and cleared up everything afterwards.

Really impressed with the product, service and company as a whole and intend to purchase the 'preventer' annually so as to keep the stonework gleaming.

I cannot recommend this lovely company highly enough!

"Works really well, but goes nowhere"

Works really well. Goes virtually nowhere.
But if you can afford it, go for it.
Just remember, it is not diluted with water, so 5L is the minimum to buy, in my opinion.
It works, where others do not, and does not pollute or harm soil.

"Just perfect."

Just perfect.

I have been using the preventer on my patio now for the past 4 years and I can honestly say it works brilliantly. Even had someone think we had a new patio. Expensive but I think worth it.
