The Rule was revised and clarified on January 2, 1984. As a result, consumers benefit from clearer and more complete care instructions required by this revision. Common terms are to be used by the manufacturers. The manufacturer is required to list only one method of safe care for the garment, even if other safe methods may also be used. The manufacturer does not have to warn you about other care methods that may not be safe.
Some labels give both fiber content and care.
It is important to read and follow the label. If no ironing instructions are given, it should not be necessary to iron the garment. If ironing is needed to preserve the garment's appearance, instructions must be given. The label need not mention any ironing temperature if the regular use of a hot iron will not harm the garment. If bleach is not mentioned, any type of bleach may be used, when needed.
