No Dry-Cleaner Necessary

It has happened again: You have an important meeting, you’re already running late and of course you’ve forgotten the most important part. Your suit hasn't been to the dry-cleaner. Consequently, you immediately start panicking and don't know how to deal with this emergency.
Just a reminder: If you are the proud owner of a Hundred Dollar Suit already, stop reading. Hundred Dollar Suits' fiber is wrinkle-resistant, so that you don't have to concern yourself with timely and expensive trips to the dry-cleaner.
Everyone else: Don't worry, we've got your back. There are several ways of refurbishing your suit to its original condition without visiting a dry-cleaner.

Sponge and Press

There is a method that is called “Sponge and Press”. You’re going to see why in a minute. Lay the jacket or trousers on the ironing board, get a slightly damp sponge and some soap and start rubbing the stains. Dab the soap away with another sponge or a cloth, which will be slightly damp. Use a pressing cloth and give a finishing press to the garment. Just in case you don’t know what a pressing cloth is: It is the term used for that piece of fabric you cover your delicate fabrics with when ironing or steaming them.
Finally, hang it to air in a warm place for a couple minutes, like your boiler cupboard or airing cupboard.

Using a Steam Cleaner

You could also just apply a steam cleaner.  If you haven't got one by hand, try leaving the suit on its hanger and holding a steam iron or a steam generator iron vertically. Then press the steam release button and steam-clean it that way.

The Steamy Bathroom-Method

Last but not least, you can try this out: If you realize that your suit is not ready to wear right after waking up in the morning, jump in the shower, turn up the heat and take your suit with you. No, not what you’re thinking. Don’t wear it, instead hang it up nicely inside the hot and steamy bathroom. This kills several birds with one stone: Your suit is turning crease-free while you’re enjoying a nice and relaxing shower.
