Have you noticed that after several washes, your water-repellent jacket isn’t performing like it used to—water no longer forms droplets on the surface, and the fabric feels worn or less protective? Even the most durable technical garments can lose their performance capabilities without proper care. This article answers the most frequently asked questions about washing and caring for functional garments, helping you avoid damaging mistakes.

Q1: What type of detergent should I use for technical apparel?

Use a neutral (pH-balanced) detergent. Neutral detergents are gentle and less likely to leave residues that compromise breathability. Avoid fabric softeners, bleach, stain remover, and darks detergents.

Q2: Can I scrub stubborn stains with a brush?

Avoid hard brushes. Hard bristles may damage technical fibers. For spot cleaning, use a soft brush or gently rub by hand to protect the fabric's integrity.

Q3: Can I wash technical apparel with regular clothes?

Generally, not recommended. After outdoor use, functional garments may carry sweat salt stains, dirt, and bacteria. Mixing them with other garments can cause cross-contamination or damage from abrasion due to different materials. If time-constrained, refer to Q6 for how to safely machine wash.

Q4: Can I machine wash functional garments?

Yes, but select “delicate” or “gentle” cycles. This minimizes mechanical abrasion to membranes and coatings. Always place garments in a laundry bag and avoid spin settings that excessively twist or stretch the garment.

Q5: Can I tumble dry technical apparel?

Yes, but only on low heat and low speed. High heat can degrade water-repellent membranes or alter material properties. Use the “Tumble Dry Low” setting to preserve elasticity and fit.

** What is Tumble Dry Low? 💡

Tumble dry low (or Delicate/Gentle cycle) is ideal for woven fabrics, like sports garments. It’s especially important to dry spandex/exercise clothing on low heat because it helps retain the garment’s performance.

Q6: Should I use a laundry bag when washing functional garments?

Strongly recommended. Laundry bags help protect delicate features like membrane and zipper. They prevent scratches in the machine drum and reduce the risk of tearing or pilling.

Q7: Can I wash technical clothing with hot water?

Keep water temperature below 40°C (104°F). High temperatures may cause adhesive tape to peel, delaminate, or weaken membranes.

Q8: How often should I wash functional clothing?

Depends on usage. Jackets are typically cleaned seasonally or annually to prevent the buildup of sweat and dirt, which can degrade the fabric’s performance.

Q9: Are there any extra care tips for dry suit?

Yes. HwaFune recommends rinsing your dry suit with clean water immediately after waterbased activities. Lay the garment flat with the outer surface facing up to dry. This prevents salt crystal formation, which can damage waterproof structures and compromise performance in marine or high-humidity environments.

🧵 Care Checklist

✅ Zip and secure everything before washing.

✅ Hang garments in a dry, well-ventilated area.  

✅ Tumble dry on low heat to reactivate DWR.
