Koi II mono pattern – large silk chiffon scarf

Dry clean.
Silk and wool are protein fibres which naturally repel dirt and hardly take on any smells, so they don't need to be cleaned often.

Steaming the scarf works wonders – it removes all wrinkles and also 'desinfects' it (removing potential smells and killing microorganisms), and it usually ends up looking like fresh from the cleaners. For this you can use a garment steamer or simply hold it approximately 2ft / 70cm over a boiling kettle for a few seconds (don't scold yourself in the process :)

If it needs a clean, dry cleaning is recommended.
Lukewarm water and mild silk/wool detergent would not damage the print, but for the feel of the silk or wool it's still better and safer to dry clean it.
