Product Reviews
By Alfred Blair-Smart

My order was sent very quickly but I had to wait a few days for the weather to behave before I used it. Like other customers we have been very pleased with the results of the patio cleaner as some of the Indian sandstone was covered with algae and only a few places will need a second application. I would not hesitate to recommend this product..

I purchased the xtreme cleaner and the wet look finish a good few weeks ago before we managed to get great weather. They are both great products easier use than you think made doing the project a lot more enjoyable to do and complete. Realy realy pleased shame cannot share before and after pictures. Many thank smart seal team.

I actually didn't expect this patio cleaner to work quite as well as it did. We inherited the patio with the house and it clearly hadn't been cleaned at all, it was so black we didn't even know what colour the slabs w ere supposed to be. I used the extreme clean first, which made a massive difference, then the black spot remover. Turns out the slabs are a buff colour, and they look brand new. A lot cheaper than installing a new patio, great products well worth a try.

Technical

Application:

  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.

Q: Can this be used on solar panels to remove black spot and lichen? Thanks

Andrew

A: No, this would be too agressive on solar panels. We would suggest for solar panels only using a form of concentrated household detergent. Hope that helps
