How do you steam a suit or a blazer without damaging the fabric?

A good suit or blazer is an investment you want to keep looking neat and well-maintained. But after a long day’s wear or after storing them in the wardrobe, creases can form. Ironing isn’t an option: the heat can flatten the fibres and cause shiny patches. The best solution? Steam!

A garment steamer removes creases quickly and safely, without damaging the fabric. But how do you do it properly? In this blog, we’ll explain step by step how to steam a suit or jacket like a professional.

1. Choose the right steamer

Not all steamers are suitable for suits and jackets. A powerful steamer with a metal nozzle works best, as it distributes heat evenly and doesn’t over-moisten the fabric.

A model such as the Jiffy garment steamer with metal nozzle (J-2000 M) is ideal for home use and guarantees an efficient and safe way to remove creases from your suit or jacket. For more intensive use, the Jiffy professional garment steamer (J-4000 M) offers greater power and durability.

2. Hang up your suit or blazer

Use a sturdy hanger to ensure the shoulders of your blazer or jacket do not lose their shape.

Make sure the fabric hangs freely so that the steam can penetrate properly.

3. Steam-ironing without damaging the fabric: the correct technique

Hold the steamer about 5–10 cm away from the fabric.

Move the steamer head from top to bottom in smooth, fluid movements.

With your other hand, gently pull the fabric taut to make creases disappear more quickly.

Focus particularly on the lapels, shoulders and sleeves, as this is where most creases form.

With a powerful steamer such as the J-4000 M, you not only remove creases but also refresh the fabric without resorting to dry cleaning.

4. Special precautions for delicate fabrics

Wool and cashmere – Steam from a greater distance and allow the fabric to dry thoroughly after treatment.

Linen and cotton – These fabrics can withstand a little more steam, but glide the steamer quickly over the fabric to prevent it from remaining damp.

Synthetic fabrics – Use a lighter steam setting to prevent overheating.

5. Leave to dry and hang up your dress or jacket

After steam ironing, the fabric will be slightly damp. Hang your dress or jacket in a well-ventilated place to allow it to dry completely. This prevents new creases from forming.
