How to clean each type of shutter: plastic, aluminum, wood, PVC…
Plastic. If they can be disassembled, the ideal is to take them to the bathroom and wash them carefully with warm water and soap.
Wood. To wash them, you can use a mixture of two equal parts water and vinegar. Avoid chemicals, which can be very aggressive.
Aluminium. They can be cleaned like plastic ones, taking care not to let them rust.
PVC. In this case too, it is recommended to wash them with water and soap, preferably liquid and Marseille soap.
