"Dry Clean Only" is a care label instruction found on clothing that indicates the item should not be washed with water. Instead, it requires professional cleaning using a solvent, typically perchloroethylene, to remove stains and dirt without damaging the fabric. This method is often used for delicate materials like silk, wool, and certain blends that can shrink or lose shape in water. Following the "Dry Clean Only" label is important to maintain the garment's appearance and longevity. Ignoring this instruction can lead to irreversible damage, such as fading, shrinking, or distortion of the fabric. Proper care ensures that the clothing remains in good condition for a longer time.
