Abstract
A cover includes a wear detection component. The wear detection component includes a wear layer and a visual wear indicator. The wear layer is designed and configured to reduce its thickness to a threshold thickness, or to disintegrate, after a preselected number of cleanings have been experience by the cover. The visual wear indicator is configured to indicate to the user that the cover has been through a threshold number of cleanings. When the wear layer has reduced its thickness to the threshold thickness, or has disintegrated, the wear layer reveals the visual wear indicator, indicating to the user that the cover is ready for replacement.
