Customer Reviews

I am disappointed. My driveway has improved a bit, but I cant justify another 2 double containers to do it again undiluted. I cannot recommend it. Andrew Chalmers

By Andrew Chalmers

Tried this out on dirty pavings and patio and am very pleased with the results, it is nice to have some colour back. It is straightforward to use and does what you say - recommended.

By John Lee From Herefordshire

Applied extreme clean to my block paving. Very pleased with results.

By Kenneth Knowles

Brilliant. Did a perfect job on my patio. Much better and quicker than my power washer.

By Mel Lloyd

Smart seal for block paving super product does the job try it you won't be disappointed staff are great and helpful

By Alun Jones From alunjones124@gmail.com

I followed the instructions to the letter and was very disappointed at the results even after two applications,simple hosing made no difference and had to jet wash my entire drive . Fair enough my block paving is twenty plus years old but I expected better. SMARTSEAL REPLY- We spoke to our customer, agreed, on very old or surfaces in poor condition, jet washing at a low level plus, using the product might be required to acheive the desired result.

By Gary Guest From South yorks

Used Xtreme Cleaner plus sealant on my Indian Sandstone patio that is very porous and a nightmare to keep clean . 1 year since being cleaned and still looks good. Certainly recommend products.

By Nick Carter From Stowmarket

the best patio cleaner I have used. Very effective at removing black algae scum and leaving a brighter surface. May need a second go on difficult out of sun areas, but worth doing. I used at 1:7.5 strength initially and 1:10 for second. Must be kept damp, do not let go dry for a couple of hours until you wash it off with low volume pressure sprayer

Powerful and Effective Patio Cleaner

Remove black spot from block paving, concrete or natural stone on patios. *Not recommended for use on Tarmac*

PatioClean Xtreme is a fast acting, high performance patio cleaning product, with four powerful active ingredients. PatioClean Xtreme offers the simple way to keep any patio clean often avoiding the need for pressure washing. Simply dilute 1:1 and apply to a wet surface by watering can or sprayer. It is important that the patio remains wet for 1 hour. Then wash away with water from hose or pressure washer. For areas of heavy soiling, scrub into surface or re-apply.

PatioClean Xtreme is a powerful cleaning product, which combines with a biocide to slow down future contamination.

For Removal of

  • Black Spot
  • Algae and Lichens
  • Moss
  • Surface Grime

5 litres of product will clean and treat approximately 40 m of flagstone, natural stone, or block paved patios. Wear appropriate safety wear at all times. See technical page for more information.



Sweep away loose debris and areas with heavy build up of moss. Firstly wet the surface of the patio with water. Dilute PatioClean Xtreme at a ratio of 1:1. Then apply liberally using a watering can or sprayer, leave on the surface for approx 60 minutes or longer before cleaning off.

It is important the patio remains wet throughout during 60 minute period, as the product becomes inactive once dry. Most ingrained organic matter and grime will be removed after one application, but sometimes a second application may be required to remove all black and white spot algae.
