After experiencing all benefits offered by a greenhouse shading agent or coating, the greenhouse should be cleaned for autumn and winter. Removers were developed to remove greenhouse shading agents from greenhouses. These give you the possibility to easily and quickly remove the shading agent from the greenhouse. 

Tips to remove greenhouse shading agents

We provide several tips below to make the removing of shading agents from the greenhouse as easy as possible:
  • Carefully spray the roof with remover by following the recommended dosage on the package, so that the greenhouse shading agent ''breaks''. In this way, it is removed from the greenhouse easier.
  • Always use the solution prepared within 6 hours for optimal functioning. After 6 hours the solution should not be used anymore, since the functioning will have reduced. This will make it more difficult to remove the shading agent and the risk for attempt might be necessary.
  • Gradually apply the solution to the roof of the greenhouse. It is an option to make use of a greenhouse roof cleaner. It's also possible to manually apply the product to the roof of the greenhouse. However, this way of working is less precise, takes more time and brings along more risks. 
  • Make sure to discharge in a ditch. The shading agents Q3 White and Q4 White do not contain any components harmful to the environment. If you make use of a different product, make sure to check if it is allowed to discharge in a ditch. 
  • It's easy to remove a greenhouse shading agent, however a good planning is needed. A rain shower will cause the shading layer or coating to flush off the roof of the greenhouse, completely cleaning the roof. It is recommended to apply your remover just before a good rain shower. If rain isn't expected but you have applied remover to the roof of your greenhouse, it might be necessary to apply the remover for a second time. 
  • In order to prevent a change in the pH level of the water in your silo, close the water catch basin while using a remover.
