Application:
- Brush off any dirt or loose debris from the surface
- Lightly dampen area with water
- Apply NEAT using a watering can or sprayer (do NOT dilute)
- Work in by brush or stiff broom
- Make sure that surface area doesn't dry out
- Leave on surface for 1-2 hours before rinsing off

It is important the surface remains damp during application, 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. If a second application is required, leave to dwell on the surface for a longer period (2-3 hours) before rinsing or pressure washing off.

Q: Will this harm wildlife, birds? There is no life in my new pond but the birds drink from it.
A: Like many domestic cleaners, this product contains some powerful ingredients, hence the name Xtreme Cleaner. If washed away properly after use, it would not cause any harm. But it would not be recommended for cleaning a pond. If it is Green & Black Algae you are looking to remove, our 'green clear' product is made up of far 'gentler' ingredients, it can be applied to the surface and just left to work, without risk of harming wildlife. Hope that helps.
Q: Can this be used on Indian sandstone?
A: Yes, our Xtreme range has been formulated to be used on natural stone, so the Xtreme Block Spot Remover will do a great job on your sandstone.
Q: My patio is surrounded by grass. Will washing it off kill/damage grass and plants?
A: As per the application video, if you wet the susceptible areas with water before and after use, the Patio Xtreme will cause no harm to grass or plants.
I used the black spot remover on a 4 year old honed sandstone terrace of around 300sqm. The terrace was quite badly marked and nothing else had shifted it. We were quoted over 3k to clean and seal it! I followed the instructions carefully - wetted the stones first and soaked the surrounding grass and plants. After 2 hours I pressure washed the terrace and against all expectations the terrace is literally like new. Quite amazing. Def use protective clothing and old clothes as the product will bleach fabrics. Excellent product.
This black spot remover really works. I was a bit sceptical as Id been told, its impossible to get rid of once black spot had invaded my Indian sandstone. Tried it as a sample on the worst affected slab. Just sprayed it and left it. After about 15 minutes I could see the spots fading. Half an hour theyre gone. Brilliant! Sprayed the rest of the patio (25sq m), and still got about half a container left. All sorted. I would highly recommend this product.
