Using this waste bin is easy. Just open the locked door with the provided key, and you can dispose of waste through the self - closing panel. When the bin is full, simply remove the waste bag and replace it. For installation, it can be surface - mounted as it comes, or if you prefer, you can remove the skirt and recess - mount it. Keep in mind to use the same key as other Bobrick washroom accessories for the lock. To maintain it, wipe the stainless - steel surface regularly with a mild cleaner to keep its satin finish looking great. Avoid using abrasive materials that could scratch the surface.
