Abstract
Abstract This invention relates to a disposable multilayer pliable sheet, which can be used for both cleaning and polishing metal, one side of the sheet having the cleaning ingredients and the other side having the polishing ingredients. The treated sheet and the method of preparing it are novel as the cleaning and polishing ingredients are mixed together and applied to the cleaning side of the assembled sheet, the cleaning ingredients of the mixture being retained by the cleaning side of the sheet and the polishing ingredients of the mixture passing through to the polishing side of the sheet.
