Start with the care label on your abaya. Cleaning and pressing instructions vary with the fabric, lining, and embroidery.
Cleaning
Check the label for washing or professional cleaning instructions. Handle embroidered edges gently, and test a new cleaner on a small inner area if the care label allows it.
Pressing and storage
Follow the temperature shown on the label when pressing. Use a suitable hanger and give the fabric room to hang without compressing the sleeves or edges.
