Always iron silk when it is slightly damp. Setting: Use the iron on low heat or silk/delicate setting.Make sure your iron is clean so it won't transfer dirt onto the silk. It's best to turn your silk item inside out for ironing. Wrinkles If you have stubborn wrinkles, you can try steaming them, but make sure the temperature is not too hot. I always use distilled water in my iron to avoid any water stains, especially on my silk pillowcases. Also avoid spraying with your regular spray bottle because this can be the main culprit for water stains - use distilled water in a special spray bottle. Don’t let iron sit Keep the iron moving – don’t let it rest on an area for more than a few seconds. This will avoid damaging the sheen of the silk. If your iron does not have a silk setting, lay a cloth between the silk and the iron. Keep the silk taut as you iron to prevent further wrinkles developing. Let the silk pillowcase cool on the ironing board before removing it. This lets the silk settle.
