Fill the water tank according to the product instructions. Some models have a removable water tank that you can fill separately, while others require you to bring the iron itself into the sink. If you have a removable water tank, follow the product instructions to clip the water tank back into the iron. Plug in the iron.
Check the label on the garment to determine the correct fabric setting. Set the iron's temperature level accordingly and wait for the soleplate to heat up. Some models have lights that come on when the iron heats up and turn off when the desired temperature is reached. Turn on the steam function when the iron is hot.
Lay the garment on the ironing board and iron as usual, moving the iron with the texture of the fabric. The iron will automatically release steam as you work. Iron a piece of fabric just long enough to smooth it out, not long enough to dry it. After finishing ironing, the fabric should be slightly damp. If you're ironing a fleece fabric, such as velvet, place the iron slightly above the garment rather than pressing down on the material.
If the water won't damage the fabric, use the iron's spray function to spray especially deep wrinkles. Iron on damp parts to loosen wrinkles. Some materials can appear speckled when sprayed, so check the garment's label before using this feature.
When you want to put the iron down, put it on your heels. When done, unplug the iron. While the iron is still hot, carefully empty the water. Place the iron on your heels until completely cool, then wrap the cord loosely around the iron and tuck it away.
