If you have a louvered door, it’s important to clean it regularly. This will help keep the door clean and free of dirt, dust, and other debris. To clean a louvered door, first remove any obstructions. Then use a plunger to suction onto the top lip of the door and pull until all the dirt and debris has been dislodged. Be sure to rinse off any excess water before returning the door to its original condition.
