Using this Fisher & Paykel fridge door shelf dairy cover is easy. Just place it on the designated left - hand short fridge door shelf. When you're ready to clean it, simply remove it from the shelf and wash it with mild dish soap and warm water. Rinse thoroughly and let it dry before putting it back. As for the mounting pin (if you purchase it), follow the basic instructions that come with it to attach it securely. A few things to keep in mind: always check your fridge model number against the compatible list to make sure this cover is the right one for your appliance. Also, handle the plastic cover gently to avoid cracking or breaking it. For long - term maintenance, try to keep the cover away from direct sunlight and extreme temperatures as this can cause the plastic to warp over time.
