The Philips 3000 Series STH3020/70 steamer is suitable for most fabrics, but certain precautions should be taken. It is particularly good for fabrics such as cotton, linen and silk, but it is advisable to check delicate or special fabrics such as wool, velour or leather before use. It is always a good idea to read the manufacturer's instructions and garment labels to ensure that the steamer is not harmful.
