1. Do not use cleaners, sponges, or vacuum cleaners to remove the dust from the frame, and use special cleaning tools to clean the decorative paintings.
2. Usually you can use a soft brush or feather duster to clean the decorative painting, and then wipe it with a clean cotton cloth dipped in water.
3. If there is oily smoke on the decorative painting, you can wipe it with light soapy water and clean water, and then use a dry cloth or paper towel to soak up the water on the painting.
