Gear Care & Maintenance Protocols
Routine cleaning and proper storage prevent seam delamination, mildew odor, zipper failure, and water-repellent breakdown. Follow these studio-verified procedures:
1. Luggage Cleaning (Hardshell & Softside)
- Hardshell (Polycarbonate, ABS, Polypropylene): Clean exterior surfaces with warm water, mild dish detergent, and a soft microfiber cloth. Never use solvent-based cleaners, acetone, or abrasive scrub pads, which strip the protective clear-coat. For tarmac scuffs, apply a small amount of non-abrasive automobile polishing paste or a damp melamine foam sponge (Magic Eraser) with very light pressure.
- Softside (Nylon, Polyester, Cordura): Vacuum out dust, crumbs, and sand from all interior corners and zip pockets. Sponge exterior fabric with warm water and wool-safe technical detergent (e.g., Nikwax Tech Wash). Do not soak the internal structural backboards. Allow to air-dry completely in a shaded, ventilated room away from direct heating radiators.
- Wheel & Handle Lubrication: Clean sand and hair from wheel axles using compressed air and tweezers. Spray a dry silicone lubricant (never WD-40, which attracts dirt) directly onto spinner bearings. Wipe telescoping aluminum handle tubes with a dry silicone cloth to prevent jamming.
2. Tent Care, Waterproofing & Storage
- Pitch & Sponge: Never machine wash a tent. Set the tent up in a backyard or garage. Sponge dirt and bird droppings off the flysheet using a non-detergent technical soap.
- Seam Sealing & DWR Restoration: If water stops beading on your tent fly (like the Quechua MH100 XXL or Eurohike Sendero 4), clean the surface and apply a spray-on fluoropolymer-free water repellent (such as Nikwax Tent & Gear SolarProof). Inspect underside seams for peeling polyurethane tape; reseal failing seams using brush-on seam grip sealer.
- Storage Invariant: Never store a tent damp. Mildew can permanently dissolve PU waterproof coatings in under 72 hours. Ensure 100% bone-dry storage in a loose, breathable cotton sack rather than a tightly cinched stuff sack.
3. Sleeping Bag Laundering & Loft Maintenance
- Synthetic Bags: Bags like the Decathlon Quechua Arpenaz 10° can be laundered in a front-loading washing machine on a delicate 30°C cycle with liquid technical cleaner. Avoid top-loaders with agitator impellers, which tear internal baffles. Tumble dry on the lowest possible heat setting or air-dry flat across a drying rack.
- Loft Protection: Do not store sleeping bags compressed in their travel stuff sacks. Hang them in a closet or keep them loosely packed in a large mesh storage sack to prevent hollow synthetic fibers from permanently flattening.
4. Hiking Boot Conditioning & Membrane Protection
- Cleaning: Remove laces and footbeds. Scrub caked mud with a stiff nylon bristle brush under cold running tap water. Never use warm water or dry boots near open campfires or radiators, which causes leather uppers (such as on the Merrell Vego Mid) to shrink and crack.
- Conditioning: Treat nubuck and full-grain leather boots every 3-6 months with beeswax conditioner or technical leather proofing cream. On synthetic boots like the Gelert Horizon Mid, apply breathable fabric water-repellent spray.

GearBuddha Editorial & Testing Standards FAQ
How does GearBuddha obtain products for testing?
We purchase over 90% of our reviewed equipment anonymously through public retail channels (including Amazon, Decathlon, REI, and direct brand websites) using our own editorial budget. When manufacturers occasionally provide review loaner units, we explicitly disclose the loaner status and never accept conditional terms, pre-approval review drafts, or paid product placements.
How do affiliate commissions affect your ratings?
Our scoring and recommendations are 100% decoupled from affiliate relationships. If a product fails our water column test, exhibits sloppy stitching, or breaks in our drop trials, we call it out explicitly—regardless of whether that brand offers an affiliate program. We routinely recommend budget gear from brands that offer zero affiliate incentives when those products outperform high-priced designer alternatives. Read our full affiliate disclosure.
How can I request a specific gear review or suggest a test?
We welcome gear recommendations, real-world traveler failure reports, and laboratory testing suggestions from our readers. Please reach out to our editorial desk via our contact page or explore our about page to learn more about our testing philosophy.
