Patio Clean XTREME Powerful Concentrated Cleaner for Black Spot, Algae & Lichen
Product Reviews
By M F

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.

Have to agree with the other reviews noted. I have used this patio cleaner for the first time and was amazed at how quickly it reacted. I am in the process of re ordering to enable me to complete the rest of the paths and patio area.

I have to say guys what a great patio cleaner this is, I got to work on this project Saturday morning early and followed the instructions from a YouTube link And the results were great so thanks for all your help. Great service great products I personally would pay just a few pounds more to get the results Thanks again

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.

Response from George

Q: I’m looking at buying some of your extreme clean product to clean my driveway which also has quite a lot of black spot around the perimeter the driveway mainly consists of block paving with the edging where the black spot is being made of stone Will the product clean it and remove the black spot. Another potential issue is that the angle of the run off of the driveway leads into a septic tank. Will the product damage the functioning of the septic tank if so do you have any suggestions or alternatives/ advice Thanks in advance

Mr Jon Hutchings

A: If you follow the instructions on the label and our 'how to' guide videos, harming plants, wildlife and the septic tank would be avoided. Hope that helps.

Response from George

Q: We have used your black limestone sealer, which covered well in 2 coats, but got damaged when we used the pressure washer, not realising that you're not meant to. Will resealing cover the damaged, faded areas or have we ruined our sandstone? How should we clean it in future?

Kate

A: We we would suggest resealing the damaged areas to create a uniform finish. Then moving forward with an occassional treatment of Xtreme Cleaner or Green Clear to keep the stone looking nice, without the need for aggressive cleaning.
