Didn’t work

It Definitely Works Needed to order more and this was delivered next day at no extra cost.

The product was extremely good and removed most of the black spots from our Indian stone patios.

It works great on black spot. Some areas needed a second application but ended up ordering double the quantity recommended as ran out half way through. So have spent over £250 cleaning my patio. Would a generic chemical from other well known sites have done the same job for approx a tenth of the price ? Probably, but who’s to know.

Great products with great results!!

Excellent- read about PBSR on RHS and thought I can’t go through another year spending three days cleaning my natural stone pavings which was back breaking. Done in 6 hours. Worth the money or counter balanced water and electricity over three days v 6 hours.

Fantastic product, works exactly as described, very prompt delivery

Happy to answer any questions we had and it’s not harmful.

Delivered quickly, easy to use and gave a great result, saving hours of jet spraying.

Brilliant product, does exactly what it says. But expensive.

Some stones came up really well others even after 4/5 treatments have a lot of spots left. Customer service said that all spots must be removed to prevent spots coming back.

Order easy, delivery quick, the product that I have used before has been excellent.

Cleaned the Indian sandstone paving of dirt, but only partially effective on black spots

Only had 2 litres which did not cover all patio’s. First application, black spot still there, have ordered more( 4 litres) at £70 . If there are black spots visible will try bleach at 0.70 pence.

You were pleasant and efficient on the phone .the order came very quickly.no problems.thank you.

prompt delivery

While expensive it was better than two other products that were also used. It worked and the the patio looks much better

Expensive but effective even on black limestone

Easy to use and works . Was expensive but I was amazed at the results Limestone patio looks like new
