Seems to be doing the job of killing off the red algae on our rendering just by spraying it on.

Good value for money...because it did what I wanted it to do! Easy to use, just follow the instructions and use a clean stiff broom or brush on the walls and in 24 hours red algae gone. Takes hard work but the results are worth it.

Used to the instructions on the pack on black algae created by sea gull fouling. The algae appears to have been killed off but to remove it from the building it will need to be pressure washed whereas the product guidance indicated that the algae would disappear after three days. Hoping that the algae has been killed off and does not reappear.

Have used Algae Clean on my K Rendered property and am pleased with the result. The property had a lot of red stains on it but Algae Clean as removed them. It does not appear to work on black stains?
