For best results, we recommend not applying HG "green algae remover" at an outdoor temperature below 10°C. The effectiveness of this product may be affected by other pollution than green algae on the surface. The active substance also adheres to the pollution, preventing it from fully working on the green algae. For patios made of non-acid-sensitive tiles such as gravel tiles, etc., which are not only contaminated with green algae, it is recommended to first clean them with HG "patio tile cleaner" and use HG "extreme power cleaner" (super remover) (HG product 20) for acid-sensitive surfaces, such as
hardstone/blue stone, marble, etc. After that, HG "green algae remover" can be applied to prevent green algae. Follow the instructions to prevent danger to humans and the environment. Treating hardened surfaces next to watercourses in the fight against green algae is not allowed. It must be prevented that the liquid reaches surface water.
Never spray or pour the solution directly on grass and plants; HG "green algae remover" becomes ineffective when it comes into contact with synthetic detergents.
Store frost-free.
