After a muddy hike, rainy hill walk, or weekend camping trip, your outdoor gear usually ends up needing a wash. For many people, the instinct is simple — throw it in the washing machine with the same detergent used for everyday laundry.

But here’s the catch: household detergents can seriously damage outdoor clothing and equipment.

Modern outdoor gear relies on advanced fabrics designed to keep you dry, warm, and comfortable in unpredictable weather. Washing these materials with standard laundry detergent can reduce their performance and shorten their lifespan.

If you want your gear to keep performing in the mountains, forests, or on the trail, it’s important to understand why specialist cleaning products like Grangers are the better choice.

The Hidden Problem With Household Detergents

At first glance, laundry detergent seems harmless. After all, it’s designed to clean clothing effectively.

However, most household detergents contain ingredients that are not compatible with technical outdoor fabrics.

Typical detergents often include:

• Surfactants

• Optical brighteners

• Fragrances

• Fabric softening agents

• Residue-forming additives

While these work well for cotton shirts or everyday clothing, they can interfere with the delicate construction of waterproof and breathable materials used in outdoor gear.

1. Household Detergents Can Clog Breathable Membranes

Many outdoor jackets rely on waterproof membranes such as:

• GORE-TEX

• eVent

• Pertex Shield

• Other technical waterproof fabrics

These membranes are designed with microscopic pores that allow sweat vapour to escape while preventing rain from entering.

Regular detergents can leave behind residues that clog these tiny pores.

When this happens:

• Breathability drops significantly

• Moisture gets trapped inside the jacket

• You may feel damp or clammy during activity

In other words, the jacket may technically still be waterproof, but it becomes far less comfortable to wear during active use.

2. Detergent Residue Affects Water Repellency

Most waterproof jackets feature a Durable Water Repellent (DWR) coating on the outer fabric.

This treatment causes water to bead up and roll off the surface instead of soaking into the material.

Household detergents often leave behind invisible residues that attract moisture. Over time, this can cause the outer fabric to absorb water instead of repelling it.

When that happens, you may notice:

• Wet patches appearing on the jacket

• The outer fabric becoming saturated

• The jacket feeling heavier in rain

Even if the waterproof membrane is still working, a soaked outer fabric can significantly reduce comfort and insulation.

---

3. Fabric Softeners Can Damage Technical Fabrics

Another common issue with household laundry products is the presence of fabric softeners or conditioning agents.

These chemicals coat fibres to make clothing feel softer, but they can cause problems for technical materials.

Fabric softeners can:

• Block breathable membranes

• Reduce moisture-wicking performance

• Leave oily coatings on synthetic fabrics

For outdoor gear designed to regulate moisture and temperature, this can significantly reduce its effectiveness.

---

4. Additives and Fragrances Build Up Over Time

Regular detergents often contain perfumes and optical brighteners designed to enhance the appearance and scent of clothing.

However, these ingredients don’t always rinse out completely — especially from thicker materials like jackets or insulated layers.

Over time, these additives can build up inside the fabric, which may lead to:

• Reduced breathability

• Reduced water repellency

• Dirt and oil sticking more easily

Eventually, gear that once performed well in tough weather may stop functioning as intended.

Specialist cleaners from Grangers help:

• Remove dirt and sweat safely

• Maintain breathability

• Protect waterproof membranes

• Prepare gear for reproofing treatments

This means your gear continues to perform the way it was designed — whether you're hiking in wet conditions or heading out on a multi-day trek.

The Importance of Reproofing Your Gear

Cleaning your outdoor gear is only part of the process.

Over time, the DWR coating on waterproof jackets and clothing naturally wears down. When this happens, water stops beading on the surface and the fabric begins to absorb moisture.

After cleaning with a specialist wash like those from Grangers, many outdoor garments benefit from reproofing treatments that restore water repellency.

Reproofing products help:

• Restore water beading

• Improve performance in rain

• Extend the life of waterproof gear

When used together, cleaning and reproofing treatments keep outdoor clothing functioning properly for much longer.

Simple Tips for Washing Outdoor Gear

Looking after outdoor clothing doesn’t have to be complicated. A few simple habits can make a huge difference.

Always Check the Care Label

Manufacturers usually provide washing instructions for technical clothing.

---

Use a Specialist Cleaner

Instead of standard detergent, choose a cleaner designed for outdoor fabrics, such as those from Grangers.

---

Wash at Moderate Temperatures

Most outdoor gear washes best at 30–40°C on a gentle cycle.

---

Avoid Fabric Softener

Fabric softeners can interfere with breathability and moisture management.

---

Reproof When Needed

If water no longer beads on the fabric, it may be time to apply a reproofing treatment.

Frequently Asked Questions

Can I wash a waterproof jacket with normal detergent?

It’s not recommended. Household detergents can clog breathable membranes and leave residues that reduce waterproof performance.

---

Why are specialist outdoor cleaners better?

Specialist cleaners like Grangers are designed specifically for technical fabrics, helping clean gear without damaging waterproof or breathable materials.

---

How often should outdoor gear be washed?

Outdoor clothing should be washed whenever it becomes dirty or when performance starts to drop. Dirt and oils can actually reduce breathability over time.

---

Do I need to reproof my jacket after washing?

Not always, but if water stops beading on the surface, applying a reproofing treatment can restore the jacket’s water repellency.
