Can the dirt on the surface of UPVC shutter window be cleaned with a wet cloth?

The dirt on the surface of UPVC shutter windows can be wiped with a damp cloth. UPVC (unplasticized polyvinyl chloride) materials usually have good weather resistance and corrosion resistance, so they can withstand wet cloth cleaning.
When cleaning, please make sure to use mild cleaning agents or only clean water, and avoid using cleaning agents containing acidic or alkaline components to prevent damage to the UPVC surface. In addition, after wiping with a damp cloth, remember to use a dry cloth to dry the water, to prevent leaving water stains or causing water to enter the mechanism part of the louver.
If the dirt on the surface of the blinds is stubborn, consider using a soft bristled brush or specialized cleaning agent for cleaning. But please note that before using any cleaning agent, test it in an inconspicuous place to ensure that it does not cause damage to the UPVC surface.
In short, a wet cloth is an effective tool for cleaning the surface of UPVC shutter windows. As long as you pay attention to the usage method and choose a suitable cleaning agent, you can easily remove the dirt on the surface.
