Spot-check fabrics and carpets for color-fastness before use. Harmful if swallowed; call poison control immediately for advice. If eye contact occurs, flush with plenty of clean water and contact a professional for advice. If skin contact occurs, remove contaminated clothing and wash with soap and water. Use only in a well-ventilated area.
