10 Washing tips 10.4 Net curtains If washing curtains made from mixed or man-made fibres:  • Ask the retailer whether the curtains are machine washable and, if so, at what water temperature. • Fill the washing drum only a quarter full. • Tie up metal rollers and plastic sliders using an open weave fabric. • Use a mild detergent (use sparingly due to foaming). • With older, faded curtains, the material is weaker and may be easily damaged if machine washed. 64
