2. Avoid using hard objects to clean the ceiling: When cleaning the ceiling of the bright board, you need to pay special attention not to scrub with tools such as hard objects and cleaning balls, because this will leave tiny scratches on the bright board, thus affecting the beauty of the ceiling.
3. Carry out deep cleaning regularly: thoroughly clean the coated board once a month and deeply clean it twice. The first time, use a soft cloth dipped in water to scrub, and then use clean water to scrub. Just open the window and let it dry naturally.
4. Protect the flatness of the ceiling with proper force when cleaning: the force can be slightly larger when scrubbing the middle part of the panel, but it should be light when scrubbing the periphery of the panel, so as not to affect the flatness of the integrated ceiling.
