Waterproof Backpack Care Checklist

To keep your waterproof backpack in great shape, follow these essential steps:

• Clean Regularly: Brush off dirt, spot-clean with mild soap, and hand wash or use a delicate machine cycle when needed. Avoid hot water, detergents, or machine drying.
• Dry Thoroughly: Air-dry completely in a shaded, ventilated area to prevent mildew and odors.
• Restore Waterproofing: Reapply a durable water repellent (DWR) coating after cleaning to maintain water resistance.
• Store Properly: Store in a cool, dry place, away from sunlight, and avoid stacking heavy items on top to preserve its shape.
• Inspect and Maintain: Check zippers, seams, and straps for damage. Repair small tears with patch kits or seam sealers.

A quick clean after each use and a deep clean once a year will help extend your backpack's lifespan and keep it ready for your adventures.

Before You Clean

Before starting the cleaning process, take a few preparatory steps: inspect the bag for any damage, empty its contents, and detach removable parts.

Inspect for Damage

Give the bag a close look to spot any potential issues:

• Run your fingers along seams to check for loose threads or separation.
• Test zippers to ensure they open and close smoothly.
• Look for tears or weak areas in the fabric.

Fix any problems before cleaning to avoid making them worse. You can use waterproof seam sealers or patch kits for small repairs.

Empty the Backpack

Make sure the bag is completely empty:

• Turn all pockets inside out.
• Check hidden compartments.
• Shake out crumbs, dirt, or any other debris.
• Inspect zipper tracks for anything stuck inside.

Detach Removable Parts

Take off any detachable components to make cleaning easier and safer:

• Remove straps, frame pieces, or any accessories. Keep them in a safe spot for reassembly later.

Once these steps are done, the backpack is ready for cleaning.

Cleaning Steps

Make sure to clean your gear in a way that keeps the waterproof layer intact.

Brush Off Dirt

Start with a dry cleaning method to get rid of loose debris:

• Use a soft-bristled brush or a clean microfiber cloth to gently remove dirt.
• Work in small sections, using light circular motions.
• Pay close attention to seams and crevices where dirt tends to hide.
• Avoid stiff brushes, as they can harm the waterproof coating.

Clean Tough Stains

For spots that don’t come off with brushing:

• Mix a cleaning solution with mild, non-detergent soap made for technical fabrics.
• Apply the solution to a clean cloth instead of directly on the backpack.
• Dab gently on the stain without scrubbing.
• Focus on one spot at a time, starting from the edges.

For a deeper clean, move on to one of the washing methods below.

Washing Method

Hand Washing

• Fill a sink with lukewarm water (around 85°F/29°C).
• Add a small amount of technical gear cleaner or mild soap.
• Submerge the backpack and move it around gently.
• Use a soft sponge to clean dirtier areas.
• Rinse thoroughly with clean water until all soap is gone.

Machine Washing

• Place the backpack in a mesh bag and use a delicate, cold-water cycle.
• Add a specialized technical gear cleaner.
• Take it out as soon as the cycle finishes.
• Avoid fabric softeners, bleach, or the spin cycle to protect the waterproof layer.

Drying and Waterproofing

Let It Air Dry

After cleaning your waterproof backpack, let it air dry completely to keep its protective features intact. Place it in a shaded, well-ventilated spot, and leave all compartments open to ensure every part dries thoroughly.

Restore Water Resistance

Once the backpack is fully dry, reapply a durable water repellent (DWR) coating to bring back its water-resistant properties. Here's how:

1. Ensure the backpack's surface is clean and completely dry.
2. Spray or apply the DWR treatment evenly across the entire surface, focusing extra attention on seams and areas that see the most use.
3. Let the coating set as directed by the product's instructions.
4. Test the coating by sprinkling a few drops of water on the surface - if the water beads and rolls off, you're good to go.

Storage Tips

Once your backpack is clean, dry, and treated for protection, storing it the right way is key to keeping it in great condition for years to come. Here's how to do it:

Pre-Storage Cleaning

Make sure your backpack is completely clean and dry before putting it away. Check every nook and cranny - like zipper tracks, mesh pockets, and reinforced areas - for any trapped moisture. This step is crucial to prevent damage while it's stored.

Pick the Right Spot

Find a storage area that's cool, dry, and allows for airflow. Avoid places exposed to heat or direct sunlight. A closet shelf or a designated spot for gear works perfectly.

Keep Its Shape

Don't stack heavy items on top of your backpack. This can cause it to lose its shape, making it less functional when you're ready to use it again. Always store it in a way that maintains its structure.

Care Schedule

Keeping your waterproof backpack in good shape requires a regular care routine. Follow these steps to ensure it performs well for years to come.

Quick Clean After Use

After every use, take a few minutes to clean your backpack. This prevents dirt buildup and helps maintain its water-resistance:

• Shake out any loose dirt or debris.
• Wipe the exterior with a damp cloth.
• Inspect and clean the zippers.
• Let the main compartment air out completely.

If your backpack has been exposed to harsh conditions - like mud, heavy rain, or saltwater - clean it thoroughly as soon as possible.

Yearly Deep Clean

Once a year, give your backpack a more detailed cleaning, especially before storing it for a while or at the start of a busy season:

• Wash all compartments and detachable parts carefully.
• Remove stubborn stains and any built-up grime.
• Check zippers, buckles, and straps for wear and tear.
• Make sure every part of the backpack is completely dry.

After this deep clean, test the backpack to ensure it’s still waterproof.

Waterproofing Maintenance

How often you need to refresh the waterproofing depends on how much you use your backpack:

• Light use: Reapply a waterproofing treatment once a year.
• Regular use: Check water resistance regularly and treat as needed.
• Heavy use or extreme conditions: Test water resistance often and reapply treatment whenever the surface stops repelling water effectively.

Summary

Here’s how to keep your backpack in top shape:

• Clean regularly: Quick cleanings after each trip prevent dirt buildup, while a deep clean once a year helps maintain its performance.
• Check for wear: Inspect zippers, straps, and seams for any damage to catch issues early.
• Dry completely: Always ensure your backpack is fully dry before storing it to avoid mildew and maintain its water resistance.
• Reapply waterproofing: Refresh waterproof treatments as needed to keep your gear protected.
• Store properly: Keep your backpack in a cool, shaded spot, and avoid placing heavy objects on top to preserve its shape.

Adjust your care routine based on how often you use your backpack. For light use, quick cleans and an annual deep clean might be enough. If you rely on your backpack heavily, plan for more frequent maintenance and waterproofing.
