Heat will set in stains and make them much harder to remove, so treat any stains or spots before you iron.

A regular ironing board works fine, though you can also use a thinner sleeve board.

Linen or cotton: hot. Synthetic fabric like acrylic, nylon, or silk polyester: cool. Polyester blend, wool: cool-warm.

To make the paste, mix 1 tablespoon of water with 2 tablespoons of baking soda. Apply the paste and then wipe the iron clean after one minute. [2] X Research source

If your iron has a steam function, you will not need a spray bottle. Make sure to fill your iron with distilled water so the water is heated before you begin. Be sure to use distilled water since tap water can contain high amounts of calcium or minerals that will damage your iron over time.

Most new irons will have an indicator light that will light up when the iron is hot. Do not begin until you are sure that the iron is at the correct temperature.

You will want to have a cloth between your iron and each part of the jacket that you are pressing. If you do not have a cloth, flip the jacket inside out and press the fabric through the lining. The lining of your jacket will likely be a different material than the rest of the suit fabric. Be sure to check the care instructions to see what material the lining is and adjust your iron’s heat settings accordingly.

Smooth out any large wrinkles before you begin pressing the jacket. If the jacket has any embroidery, turn the jacket inside out and press it through the lining rather than over the embroidery. You will need to use a cooler heat setting if you press through the lining.

Spray a small amount of water onto the fabric you want to press. Press down on sections of the back rather than gliding the iron over the fabric. You want to press the wrinkles out rather than smoothing them. If the jacket has vents, put a piece of stiff paper between the vent and the rest of the back. This helps to prevent marks being made on the layer underneath the vent. Iron the top piece of the vent, then lift it up while you press the piece that is underneath the vent.

Smooth any large wrinkles out of the fabric and lining before you start to press and spritz the fabric with water.

Jacket lapels should not be creased unless you want a hard military look. Run the iron over lapels very gently. Similarly, if the jacket has shoulder pads do not press directly on the pads or their outline will be pressed into the jacket. Pull out pockets before you press over that area so you do not press in the outline of pocket wrinkles. If there are pocket flaps, use the stiff piece of paper you used on the vents to separate the layers as you press them.

Lay the sleeve down on the board and smooth out any large wrinkles in the fabric and the lining by hand. If you are using a sleeve board, insert the board into the sleeve so you can rotate the sleeve around the board. Lay a damp cloth over the sleeve. This will help to protect the suit fabric and make pressing easier. [6] X Research source

If you do not have a sleeve board you can substitute a cylindrical container to keep the sleeve’s shape while you iron. You can use a rolled up thick magazine or a cylindrical cardboard tube and insert it into the sleeve. Be sure to cover the magazine or tube with a cotton towel before you insert it.

Allow the jacket to hang while it cools. Unplug your iron and put away your ironing board. Wait until the iron is cool to the touch before putting it away.
