Maintaining and Waterproofing Your Outdoor Gear

Quality outdoor gear is an investment. A properly maintained rain jacket can last a decade. A neglected one may fail after two seasons. Regular cleaning and reproofing dramatically extends gear life and maintains performance when you need it most.

Rain Jackets and Hardshells

How Waterproof-Breathable Fabrics Work

Your rain jacket has two waterproofing systems:

  1. The membrane (Gore-Tex, eVent, etc.): The internal waterproof layer. This rarely fails.
  2. DWR coating (Durable Water Repellent): The outer fabric treatment that causes water to bead. This DOES wear off with use, UV exposure, body oils, and dirt.

When DWR fails, the outer fabric "wets out"—water soaks into the face fabric. The membrane still blocks water from reaching you, but breathability drops dramatically because the wet fabric blocks vapor transfer. This is why your jacket feels clammy even though it's not technically leaking.

Washing Your Rain Jacket

Clean jackets perform better than dirty ones. Dirt and oils clog pores and degrade DWR.

  1. Close all zippers and Velcro
  2. Use a front-loading washer on gentle cycle (agitators in top-loaders can damage membranes)
  3. Use a tech wash (Nikwax Tech Wash or Grangers Performance Wash)—NOT regular detergent
  4. Regular detergent leaves residue that attracts water and clogs pores
  5. Double rinse to ensure all soap is removed
  6. Tumble dry on low heat for 20 minutes (heat reactivates existing DWR)

Restoring DWR

If water no longer beads after washing and heat activation:

  1. Apply spray-on DWR treatment (Nikwax TX.Direct Spray-On or Grangers Performance Repel)
  2. Spray evenly on the outer fabric while the jacket is damp
  3. Tumble dry on low heat to cure the treatment
  4. Alternative: Wash-in DWR products treat the entire jacket but also coat the inside

How Often?

  • Wash 2-3 times per season with regular use
  • Reproof when water stops beading after washing
  • Always wash before reproofing—DWR won't adhere to dirty fabric

Down Insulation

Washing Down Jackets and Sleeping Bags

Down requires special care:

  1. Use a front-loading washer (never top-loading)
  2. Use down-specific wash (Nikwax Down Wash Direct)
  3. Wash on gentle cycle with warm water
  4. Run an extra rinse cycle
  5. Dry on LOW heat with 2-3 clean tennis balls or dryer balls
  6. Drying takes 2-3 hours—check frequently. Down must be completely dry to prevent mildew.
  7. Periodically pull apart clumps of down during the drying process

Storage

  • Never compress down for storage
  • Use a large breathable storage bag or hang in a closet
  • A compressed sleeping bag loses loft over time—stuff sacks are for the trail only
  • Store in a dry area away from direct sunlight

When to Wash

  • Down jackets: Once or twice per season
  • Sleeping bags: Once per year with regular use, or when they smell or lose loft
  • Use a liner in your sleeping bag to extend time between washes

Tents

Cleaning Your Tent

  • Set up the tent and sponge-clean with mild soap and water
  • Never machine wash a tent—it destroys coatings and seams
  • Pay attention to the floor and lower walls where dirt accumulates
  • Rinse thoroughly and air dry completely before storage

Seam Sealing

Most factory-sealed seams hold up well, but check periodically:

  • Set up the tent and inspect all seam tape
  • Re-seal peeling seams with seam sealer (Gear Aid Seam Grip)
  • Apply sealer to the inside of the fly and the floor seams
  • Let cure for 24 hours before packing

Waterproofing the Rainfly and Floor

If water no longer beads on the fly:

  • Clean the tent first
  • Apply tent-specific waterproofing spray (Nikwax Tent & Gear SolarProof)
  • Apply to the exterior of the fly and the bottom of the tent floor
  • Let dry completely

UV Damage Prevention

UV radiation degrades nylon and polyester over time:

  • Don't leave your tent set up in direct sun longer than necessary
  • Use UV-protective sprays on the fly
  • Store the tent away from sunlight
  • Consider UV-protective tent footprints

Zipper Maintenance

Sticky zippers are the most common tent complaint:

  • Clean zipper tracks with a toothbrush and soapy water
  • Apply zipper lubricant (McNett Zip Care or a candle wax stub)
  • Lubricate both the teeth and the slider
  • Address sticky zippers promptly—forcing them damages the slider

Hiking Boots

Cleaning

  • Remove laces and insoles
  • Brush off dry mud with a stiff brush
  • Clean with boot-specific cleaner or mild soap and water
  • Rinse thoroughly
  • Stuff with newspaper and air dry away from heat sources (heat warps leather and degrades adhesives)

Waterproofing Leather Boots

  • Clean thoroughly before treatment
  • Apply waterproofing wax or cream (Nikwax Waterproofing Wax for Leather)
  • Work into seams and stitching where leaks develop
  • Let absorb for 24 hours
  • Buff with a soft cloth

Waterproofing Synthetic Boots

  • Clean first
  • Apply spray-on waterproofing designed for synthetic materials
  • Treat the entire upper, focusing on seams
  • Reapply every few months with heavy use

Resoling

Quality hiking boots can be resoled:

  • Look for separated soles, worn tread, or exposed midsole
  • Many cobblers and specialized shops offer resoling services
  • Cost is typically $80-150—much less than new boots
  • Not all boots are worth resoling—evaluate the upper condition too

Storage

  • Store in a cool, dry place
  • Don't store in extreme heat (like a hot car or garage)
  • Loosen laces so the tongue can dry
  • Insert boot trees or crumpled newspaper to maintain shape

Backpacks

Cleaning

  • Remove all items and shake out debris
  • Vacuum or brush out the interior
  • Spot clean with mild soap and a soft brush
  • For deep cleaning, fill a bathtub with warm soapy water and submerge
  • Rinse thoroughly and air dry with all compartments open
  • Never machine wash or dry—it can damage the frame and coatings

Waterproofing

  • Check the pack's DWR coating and reproof if water no longer beads
  • Apply spray-on waterproofing to the exterior
  • Seam seal any areas where water seeps through
  • Always use a pack liner (trash compactor bag) as primary water protection

Hardware Maintenance

  • Check buckles, zippers, and straps for wear
  • Replace broken buckles (most manufacturers sell replacements)
  • Lubricate zippers with zipper wax
  • Tighten loose hip belt screws
  • Repair small fabric tears with tenacious tape before they spread

General Gear Maintenance Tips

After Every Trip

  • Unpack everything and air it out
  • Hang sleeping bag loosely
  • Set up tent to dry if it was packed wet
  • Clean and dry cooking gear
  • Check all gear for damage

Seasonal Maintenance

  • Deep clean jackets and backpack
  • Reproof waterproof items
  • Check seams on tent and rain gear
  • Inspect boot soles and waterproofing
  • Replace worn items before they fail on a trip

Repair Kit

Keep a basic repair kit for field and home repairs:

  • Tenacious tape (for patches on fabric and inflatable pads)
  • Seam Grip (for seam repair and patching)
  • Safety pins and sewing needle with heavy thread
  • Replacement buckles for your specific pack
  • Zipper pulls
  • Cord and paracord
  • Duct tape wrapped around a trekking pole or water bottle
