A trench coat is a wardrobe staple, but washing it incorrectly can easily ruin its shape, fabric, or water-resistant finish. How to wash a trench coat depends entirely on the material, lining, and care label, and not every trench coat should be washed at home. If you are unsure or want to avoid damaging an expensive coat, a professional service like Laundryheap can clean trench coats safely using fabric-appropriate methods.
In this guide, we explain how to clean a trench coat properly, when machine washing is safe, when dry cleaning is necessary, and how much dry cleaning a trench coat typically costs.
What Is a Trench Coat?
A trench coat is a long, lightweight coat traditionally made from cotton gabardine or cotton-blend fabrics and often treated to be water-resistant. Most trench coats include:
- A structured silhouette
- A lining that may be removable
- A belt and storm flaps
- Multiple stitched panels and detailing
Because of this construction, trench coats require more care than everyday jackets.
Can You Wash a Trench Coat?
Yes, but only some trench coats can be washed, and only if done correctly.
Whether washing a trench coat is safe depends on:
- Fabric type
- Lining material
- Presence of leather, suede, or metal detailing
- Care label instructions
If the label says “dry clean only,” washing it at home can cause shrinkage, fabric warping, colour bleeding, or permanent loss of shape.
How to Wash a Trench Coat
1. Check the Care Label First
Always start by checking the care label for washing instructions, recommended water temperature, and drying guidance. If the label is missing or unclear, it is safer to avoid machine washing.
2. How to Wash a Trench Coat in the Washing Machine
Only machine-wash a trench coat if the care label explicitly allows it.
Steps:
- Remove the belt and detachable lining
- Fasten all buttons and buckles
- Turn the coat inside out
- Place it in a large mesh laundry bag
- Wash using cold water at 30°C or lower
- Select a gentle or delicate cycle
- Use a mild liquid detergent
Never use fabric softener, bleach, or hot water, as these can damage the fabric coating and structure.
3. Hand Washing a Trench Coat
Hand washing is a safer option for delicate trench coats.
How to clean a trench coat by hand:
- Fill a bathtub or basin with cold water
- Add a small amount of gentle detergent
- Submerge the coat and gently agitate
- Do not scrub or wring
- Rinse thoroughly with cold water
Press out excess water using a towel. Never twist the coat.
How to Wash a Coat That Is Dry Clean Only
If your trench coat is labelled dry clean only, home washing is not recommended.
Water can damage internal structuring, cause interfacing to bubble, and permanently alter the coat’s fit. While spot cleaning small stains with a damp cloth may be possible, full washing should be avoided. For valuable or tailored trench coats, professional cleaning is the safest option.
How to Dry a Trench Coat Properly
Drying a trench coat incorrectly can cause just as much damage as washing it.
Best practices:
- Never tumble dry
- Lay flat on a towel or hang on a wide hanger
- Allow it to air dry naturally
- Keep away from direct heat or sunlight
Once dry, light steaming can help remove wrinkles if the care label allows.
How Much Does It Cost to Dry Clean a Trench Coat?
Dry cleaning a trench coat varies from place to place, but the average cost usually ranges between £15–£30 or $20–$40. Designer trench coats, heavy linings, or intricate tailoring can increase the price, which is why many people prefer using Laundryheap’s professional laundry service to avoid costly mistakes.
Common Mistakes to Avoid When Washing a Trench Coat
- Using hot water
- Putting a trench coat in the dryer
- Washing without removing the belt
- Overloading the washing machine
- Using harsh detergents
These mistakes are the most common reasons trench coats lose their shape or finish.
When to Use a Professional Laundry Service
If your trench coat is dry clean only, made from wool or silk blends, heavily structured, or expensive, professional cleaning is strongly recommended. A specialist laundry service such as Laundryheap ensures the correct cleaning method is used, helping preserve the coat’s fit, fabric, and lifespan.
Final Thoughts
Knowing how to wash a trench coat properly can help you avoid costly mistakes. While some trench coats can be gently cleaned at home, many require professional care to maintain their structure and appearance. When in doubt, choosing expert cleaning is the safest way to keep a trench coat looking sharp season after season.
