Why cleaning your hiking backpack is crucial.

Before diving into cleaning, let’s discuss why keeping your backpack clean is essential. Over time, dirt, sweat, and moisture can build up, creating a breeding ground for bacteria and mold. Not only does this affect your backpack’s lifespan, but it can also impact your health. So, let’s get started on giving your backpack a well-deserved spa day.

How to Wash a Hiking Backpack

A dirty backpack not only looks unsightly but can also affect its functionality. Dirt, sweat, and bacteria can accumulate on the surface, leading to unpleasant odors and potential health risks. Regular cleaning helps eliminate these issues and ensures your backpack remains in top condition for your next adventure.

Preparing for the Cleaning Process

Before diving into the cleaning process, preparing adequately is crucial. Here are the steps to ensure you’re ready to give your hiking backpack a thorough wash:

1. Gather the necessary supplies

You’ll need a few items to get started. Collect the following supplies:

Mild detergent or backpack-specific cleaner: Choose a gentle detergent or a cleaner designed explicitly for backpacks. Harsh chemicals can damage the fabric and coatings.

Soft-bristle brush or sponge: This will be your main tool for scrubbing dirt and grime. Make sure it’s gentle to avoid causing any harm.

Lukewarm water: You don’t want the water to be too hot, as it can affect the backpack’s materials. Lukewarm water is ideal.

Toothbrush (for small crevices): A toothbrush is excellent for reaching tight spots and corners that may be challenging to clean with a larger brush or sponge.

Towels: Have some clean towels for drying your backpack after cleaning.

A bathtub or large basin: You’ll need a space to clean your backpack. A bathtub or a large basin works well for this purpose.

2. Empty the backpack

Before you start cleaning, ensure your backpack is empty. Check every pocket, compartment, and hidden space to ensure nothing is left inside. It’s surprising how often hikers find forgotten snacks or gear stashed away.

3. Checking for manufacturer’s instructions

Reviewing the manufacturer’s care instructions for your specific backpack is crucial. Some backpacks may have unique cleaning recommendations based on their materials and construction. These instructions will guide you on how best to clean your backpack without causing any damage.

Cleaning the Exterior

Now that you’ve prepared your cleaning supplies and emptied your backpack, it’s time to tackle the exterior. Cleaning the outside of your hiking backpack is essential to remove dirt, mud, and stains accumulated during outdoor adventures. Here’s how to do it effectively:

1. Removing dirt and debris

Fill the bathtub or basin: Start by filling your bathtub or a large basin with lukewarm water. You want enough water to submerge your backpack.

Add detergent: Add a small amount of mild detergent or a backpack-specific cleaner to the water. Be cautious not to use too much, as excess detergent can be challenging to rinse.

Submerge the backpack: Place your backpack in the water, ensuring it’s fully submerged. This allows the detergent to penetrate and start loosening dirt and grime.

Gentle agitation: Gently agitate the water with your hands or a soft-bristle brush. This helps to dislodge surface dirt and debris.

2. Scrubbing and rinsing

Focus on straps and zippers: Straps, zippers, and areas with heavy soiling might need extra attention. Use the soft-bristle brush or sponge to scrub these areas gently. Avoid vigorous scrubbing, as it can damage the fabric.

Rinse thoroughly: Drain the soapy water from the tub or basin once you’ve scrubbed away the dirt. Rinse your backpack thoroughly with clean, lukewarm water until all traces of detergent are gone. It’s essential to ensure there’s no soapy residue left behind.

Check for stains: Inspect your backpack for any remaining stains or spots before moving on. If you spot any, don’t worry; we’ll address those shortly.

Cleaning the Interior

Now that the exterior of your hiking backpack is clean, it’s time to focus on the interior. This step is just as crucial, as the interior can accumulate crumbs, residues, and even stubborn stains. Here’s how to clean the inside of your backpack effectively:

1. Removing crumbs and residues

Turn your backpack inside out: Carefully turn your backpack inside out to access the interior. This step is essential to ensure a thorough cleaning.

Shake out loose debris: Shake your backpack vigorously to dislodge and remove loose crumbs, dirt, and debris. You’d be surprised at how much accumulates over time.

Use a soft brush or sponge: If the interior is still turned out, use a soft-bristle brush or sponge to wipe down the fabric. Pay close attention to corners, seams, and pockets.

Empty pockets and compartments: If your backpack has removable compartments or pockets, take them out and clean them separately. Inspect these compartments for any hidden crumbs or residues.

2. Dealing with stubborn stains

Create a baking soda paste: For stubborn stains on the interior fabric, create a paste using baking soda and water. The paste should be thick enough to adhere to the stain without dripping.

Apply the paste: Gently apply the baking soda paste to the stained area. Let it sit for a few minutes to allow the baking soda to absorb and break the stain.

Scrub with a soft brush: After letting the paste sit, use a soft brush to scrub the stained area gently. Be patient and avoid excessive force; you don’t want to damage the fabric.

Rinse thoroughly: Rinse the interior of your backpack thoroughly with clean water to remove any remnants of the baking soda paste. Ensure that no residue remains.

Hand Washing a Hiking Backpack

Hand washing is the preferred method for cleaning most hiking backpacks, especially those made of delicate materials or with special features. Here’s how to do it:

Step 1: Fill the Basin

Fill the basin or bathtub with room-temperature water. Avoid using hot water as it may damage the backpack’s materials.

Step 2: Add Detergent

Add a small amount of mild detergent to the water and mix it well until it forms suds.

Step 3: Submerge the Backpack

Submerge the backpack in soapy water. Gently press it down to ensure all areas are soaked.

Step 4: Clean the Backpack

Using a soft brush or sponge, gently scrub the backpack’s surface. Pay close attention to areas with visible dirt or stains. Use a mild scrubbing motion to avoid damaging the fabric.

Step 5: Rinse Thoroughly

Empty the soapy water and refill the basin with clean water. Rinse the backpack thoroughly, ensuring all traces of detergent are removed. Repeat this step if necessary.

Step 6: Dry the Backpack

Squeeze out excess water from the backpack without wringing or twisting it. Lay the backpack flat on a clean, dry towel. Gently pat the backpack with another towel to absorb as much moisture as possible. Please leave it in a well-ventilated area to air dry completely.

Machine Washing a Hiking Backpack

Machine washing is suitable for hiking backpacks made of durable materials like nylon or polyester. However, always check the manufacturer’s instructions before attempting this method:

Step 1: Empty and Inspect the Backpack

Follow the same procedure mentioned in the “Preparing for Cleaning” section.

Step 2: Secure Straps and Zippers

Close all zippers, secure buckles, and fasten any loose straps. This prevents them from getting tangled or damaged during the washing cycle.

Step 3: Use a Laundry Bag

Place the backpack inside a large laundry bag to protect it during the wash cycle. The bag will prevent excessive agitation that could harm the backpack’s integrity.

Step 4: Select a Gentle Cycle

Set your washing machine to a gentle cycle with cold water. Avoid using bleach or harsh detergents that can damage the backpack’s materials.

Step 5: Air Dry the Backpack

After the wash cycle is complete, remove the backpack from the laundry bag and let it air dry in a well-ventilated area. Avoid using a dryer, as the heat can shrink or warp the backpack.

Drying and Maintenance

Having successfully cleaned the exterior and interior of your hiking backpack, it’s crucial to dry and maintain it properly. This step ensures that your backpack remains in top-notch condition for future adventures. Let’s dive into the drying and maintenance process:

1. Air drying vs. machine drying

Choose air drying: Avoid using a washing machine or dryer to dry your backpack, as the mechanical action and heat can damage the materials and straps. Instead, opt for air drying.

Hang it upside down: Find a well-ventilated area and hang your backpack upside down. Hanging it upside down allows water to drain away from the zippers and seams, preventing potential damage.

Avoid direct sunlight: While drying, avoid direct sunlight, as it can fade colors and weaken fabrics over time. A shaded or indoor location is ideal.

Be patient: Air drying may take some time, especially if your backpack is heavily padded. Ensure it’s completely dry inside and out before moving on to the next step.

2. Reconditioning and waterproofing

Recondition the fabric (if needed): Some backpacks benefit from reconditioning after cleaning. Follow the manufacturer’s recommendations for reconditioning products or treatments. This step helps maintain the fabric’s integrity and water resistance.

Apply a waterproofing spray: To prepare your backpack for rainy hikes, consider applying a waterproofing spray designed for outdoor gear. Pay special attention to seams, zippers, and high-wear areas.

Ensure thorough drying: Ensure your backpack is dry before applying any reconditioning or waterproofing products. Moisture can trap these products in the fabric, potentially affecting their effectiveness.

Tips for Specific Backpack Types

Hiking backpacks come in various shapes and sizes, each designed for different purposes. Here are some specific tips on how to care for and clean different types of hiking backpacks:

1. Daypacks

Please handle with care: Daypacks are often made of lightweight materials to keep them portable. Be gentle when cleaning, and avoid using harsh chemicals that may weaken the fabric.

Regular checks: Since daypacks are typically used for short hikes, perform regular checks for any small tears or loose stitching that may need repair.

2. Hydration Packs

Clean the hydration bladder separately: Hydration packs have a built-in water reservoir or bladder. Clean this separately, following the manufacturer’s instructions. Ensure it’s completely dry before reassembling your pack.

Pay attention to the hose: The hose on your hydration pack can develop mold and mildew if not cleaned properly. Use a specialized hydration pack cleaning kit to keep it fresh.

3. Backpacking Packs

Disassemble for thorough cleaning: Backpacking packs are often larger and have more components. Disassemble any removable parts, such as hip belts and shoulder straps, and clean them individually. Please pay special attention to the hip belt and shoulder straps, as they accumulate sweat and dirt over long hikes.

Inspect the frame and suspension system: If your backpack has an internal frame or suspension system, inspect it for any damage or dirt buildup. Use a brush or compressed air to clean hard-to-reach areas.

Waterproofing is key: Backpacking packs often carry valuable gear and clothing, so maintaining their waterproofing is essential. Regularly apply a waterproofing spray to keep your gear dry during rainy trips.

Extending the Lifespan of Your Backpack

You’ve now learned how to clean and maintain your hiking backpack effectively. To ensure your trusty companion lasts for years and accompanies you on countless adventures, consider these tips for extending its lifespan:

1. Regular maintenance

Post-hike routine: Make cleaning your backpack a routine after each hike, even if it’s just a short one. This practice prevents dirt, sweat, and moisture from accumulating and becoming harder to clean later.

Inspect for damage: Inspect your backpack for any signs of wear and tear after every trip. Check for loose stitching, frayed straps, or damaged zippers. Address minor issues promptly to prevent them from worsening.

Tighten loose hardware: Backpacks often have buckles, straps, and other hardware that can loosen over time. Periodically check and tighten these components to maintain the backpack’s stability.

2. Proper storage

Clean before storage: Before storing your backpack for an extended period, ensure it’s clean and completely dry. Leftover moisture can lead to mold or mildew growth.

Use a storage bag or cover: Consider using a breathable storage bag or cover to protect your backpack from dust and pests while in storage.

Avoid extreme temperatures: Store your backpack in a cool, dry place away from direct sunlight and extreme temperatures. Prolonged exposure to heat or cold can affect the materials and coatings.

Keep it off the ground: When storing your backpack, avoid placing it directly on the ground. Use a shelf or hook to keep it elevated and away from potential moisture.

Rotate your gear: If you have multiple backpacks, rotate their use to prevent overloading and excessive wear on a single pack.

3. Proper loading and packing

Distribute weight evenly: When packing your backpack, distribute the weight evenly to avoid straining specific areas or seams. This practice ensures the longevity of your backpack’s structural integrity.

Use packing cubes: Packing cubes can help organize your gear and protect the interior of your backpack from sharp objects or spills.

Avoid overpacking: Overloading your backpack can stress zippers, straps, and seams. Follow the recommended weight limits provided by the manufacturer.

Secure loose items: Before closing your backpack, ensure all loose items are secured. Loose gear can shift during hikes and cause unnecessary wear.

Specific Backpack Materials:

Nylon and Polyester:

  • These synthetic materials are generally the easiest to clean and can be washed using the abovementioned methods.
  • For stubborn stains on nylon, you can try using a mixture of baking soda and water.


  • Canvas requires a more delicate approach than synthetic materials.
  • Use a soft brush to remove any loose dirt and debris before washing.

  • Avoid scrubbing too hard, as this can damage the fabric.
  • Rinse the backpack thoroughly and allow it to air dry completely.


  • Leather backpacks require special care to maintain their supple texture and beautiful appearance.
  • Never immerse a leather backpack in water.
  • Instead, wipe down the surface with a damp cloth and a mild leather cleaner.
  • Pay particular attention to seams and stitching, where dirt can easily build up.
  • After cleaning, apply a leather conditioner to protect the leather and prevent it from drying out.
