How to care for your waterproof items of clothing
This article on caring for waterproof garments follows the one we wrote about drying wet footwear.
Caring for Waterproof and Water-Resistant Outerwear
Although some outerwear garments are labelled waterproof or water-resistant, they perform differently. However, they should be cared for similarly in terms of washing and maintenance. Well-maintained walking and hiking outerwear should last years, keeping you dry and warm in all types of weather.
Understanding the Difference Between Waterproof and Water-Resistant Clothing
A water-resistant jacket is often shower-proof and treated with a water-repellent coating. These garments can withstand light rain but eventually become saturated in heavy downpours.
In contrast, waterproof clothing is designed to keep you completely dry even in persistent rain. It is manufactured with a waterproof membrane and sealed or taped seams, preventing water from penetrating the fabric. Waterproof garments are constructed using a Durable water-repellent (DWR) coating or a waterproof membrane bonded into the fabric.
If your waterproof coat becomes wet, it is best to hang it up in a well-ventilated area and allow it to dry completely before storing it. This helps prevent creases and maintains its water-repellent properties.
Washing Waterproof Garments
Washing your waterproof outerwear correctly can significantly prolong its lifespan and maintain its effectiveness. Follow these steps to ensure you don’t damage the fabric or the waterproof coating.
- Remove excess dirt and mud before washing. If your coat or trousers are muddy, wipe them down with a damp sponge or hose them off before washing them.
- Check the care label for washing instructions, including the recommended temperature and cycle settings.
- Use a specialist detergent designed for waterproof clothing. Never use regular laundry detergent or fabric softener, as these can break down the waterproof coating. Many outdoor retailers sell specialist waterproof detergents, some of which include an all-in-one washing and reproofing solution. I recommend Nikwax, as it effectively cleans without damaging the waterproof layer.
- Select a gentle wash cycle at a temperature of around 30°C.
- Fasten all zips, buttons, and Velcro closures before washing to prevent them from snagging or becoming damaged.
- Empty all pockets before placing your clothing in the washing machine.
- For stubborn stains, apply a small amount of specialist detergent directly onto the affected area before washing.
- Rinse thoroughly to ensure no detergent residue is left behind, which can affect the garment’s waterproofing.
Reproofing Your Waterproof Garments
Over time, the DWR coating on waterproof clothing will wear off due to washing, exposure to dirt, and general use. If you notice that water no longer beads on the surface of your jacket or trousers but instead soaks into the fabric, it’s time to reproof your clothing.
You have two options for reapplying the waterproof coating.
Spray-On Treatment
- Hang your freshly laundered clothing in a well-ventilated area.
- Spray the reproofing treatment evenly over the outer surface, paying extra attention to high-wear areas like the shoulders and arms.
- Allow the garment to dry naturally or according to the product instructions.
Wash-In Treatment
- Add the DWR reproofing liquid directly into the washing machine (or a basin if hand washing).
- Run a gentle wash cycle, following the instructions on the reproofing product.
- Ensure the garment is thoroughly rinsed before drying.
Many outdoor brands, such as Nikwax and Grangers, offer easy-to-use reproofing solutions that help restore water repellency to your outerwear.
Drying Your Waterproof Clothing
Once you have applied the water-repellent coating, proper drying is essential to reactivate the treatment and ensure your garment remains waterproof.
- If the care label allows, the most effective way to dry waterproof clothing is to use a tumble dryer on a low to medium heat setting. The heat helps bond the waterproof treatment to the fabric.
- If tumble drying is not an option, hang your waterproof clothes in a well-ventilated area and allow them to dry naturally. A warm, dry room works well, or you can dry them outside on a sunny day.
- Avoid placing waterproof clothing on direct heat sources, such as radiators or heated towel rails, as excessive heat can damage the fabric and waterproof membrane.
Once completely dry, the garment should be breathable, clean, and waterproofed. Depending on how frequently you wear the clothing, the reproofing treatment should last for approximately four to six months before needing reapplication.
Final Thoughts
Proper care of your waterproof outerwear will extend its lifespan and ensure it continues protecting you from the elements. Regular cleaning and reproofing will help maintain its performance, keeping you warm and dry on all your outdoor adventures.
