Preheat the iron to a low setting to prevent burning. If the satin was packed away in storage, set the iron to the highest low-heat setting.
Turn the fabric inside out and lay flat on an ironing board.
Move the iron across the satin swiftly and continuously to prevent burning. Apply light pressure and use long, smooth strokes. When not using the iron, set it off to the side standing up.
Remove the garment from the ironing board, turn it right-side out and hang.
