发明名称 CLEANING ARTICLE WITH INDICATOR
摘要 The present invention is directed to a cleaning article for cleaning applications, and more specifically, to a cleaning article comprising an indicator, wherein the indicator fades during use to convey to the user that the cleaning article has met or exceeded its useful life span and needs to be replaced. In accordance with the present invention, the disposable cleaning article is comprised of a binder having a finite life span that acts as an indicator. Due to the continuous use of article the binder begins to fade and eventually is removed, indicating that usefulness of the disposable cleaning article has expired. The finite life span of the indicator is beneficial in a disposable cleaning article to act as a reminder to replace the expended cleaning article with a fresh article.
