First, heat fumigation. If there is heating, you can wash your clothes and lay them flat on the heating, and use the heat of the heating to iron them flat. I often use this method in winter. Second, silk cotton washing method. If you wash silk and cotton clothes in summer, you can directly wash them with water and dry them. The main thing is, don't twist or throw it with the washing machine. Flatten them with water. This way, the clothes will be smoother after drying. Third, hot water ironing. Just use a tea urn, fill it with freshly boiled hot water, and iron clothes like an iron. Sometimes the effect is good. Remember not to bring sandwiches into tea pots or stainless steel cups. Fourth, the weight method. After ironing, put a clean towel and press it with a heavy object for a period of time, and the natural clothes will also flatten from folds.
