By Mick MorrisFROM Gloucester

Used this patio cleaner on my sisters path. Incredible difference.

By Terry Cosshall

Really pleased with both the offer 3 for 2 of the patio cleaner and the performance of this product I use it on my patio and brickwork which was stained through plants. It does no damage but removes all staining superbly well brings both up like new with mInimum effort.

By Griffith Williams

Great product cleaned our Indian sandstone of all black spot and blemishes. Would highly recommend it will be used on the block paved drive next.

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.




  1. Sweep away loose debris & areas with a heavy build-up of dirt & grime.
  2. Wet surface area with water.
  3. Dilute Patio Clean Xtreme at a ratio of 1:1. If removing black spot, don't dilute (use neat).
  4. Apply product to surface using a watering can or sprayer.
  5. Make sure that surface area doesn't dry out before rinsing off.
  6. Leave on surface area for upto 60 minutes.
  7. Rinse area with water.

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.

Response from Rick

Q: Hi is smart seal patio cleaner ok to use near pvc windows. As just had some new ones fitted.

Ian Jackson

A: It would be advised to avoid the PVC, if possible, when using the Patio Clean Xtreme. Wetting down the PVC with water before and after use will help eliminate any problems.

Response from Ricky

Q: Hi, When applying xtreme patio cleaner it says to keep wet is this with applying more cleaner or water Regards Brian

B. Godfrey

A: When using the Patio Xtreme, you would want the cleaner to remain damp for at least an hour before washing off. You would do this with water, but not flooding it as it will dilute the product too much.
