Athletic and performance clothing is engineered to move moisture away from your body — but that same technology makes it particularly vulnerable to damage from improper washing. Fabric softener, hot water, and high-heat drying are the three things most people do that destroy performance gear. Here's exactly how to wash it properly.
The 4 Non-Negotiable Rules
✅ Rule 1 — Never Use Fabric SoftenerFabric softener deposits a coating on performance fibers that clogs the micro-pores responsible for moisture wicking. A single wash with softener can permanently reduce the performance of technical fabrics. Use a fabric rinse instead.
✅ Rule 2 — Always Wash in Cold WaterHot water breaks down elastic fibers and can cause synthetic performance fabrics to lose their shape and stretch recovery. Cold water cleans effectively and protects the fabric structure.
✅ Rule 3 — Air Dry or Low Heat OnlyHigh dryer heat is the fastest way to destroy athletic wear. The elastic fibers in compression gear and the technical coatings on moisture-wicking fabrics both degrade rapidly at high temperatures. Air dry when possible, or use the lowest dryer setting.
✅ Rule 4 — Wash Inside Out on Gentle CycleTurning clothes inside out protects the outer surface from friction and pilling. The gentle cycle reduces mechanical stress on technical fibers and seams.
Dealing with Persistent Odor
If your gym clothes still smell after washing, the issue is detergent residue trapping bacteria — not insufficient cleaning. The solution is to use less detergent, not more. Try adding a fabric rinse to break down the residue, or soak in a diluted OxiClean solution for 30 minutes before washing.

🏁 Our Verdict
Never use fabric softener on athletic wear — it permanently damages performance fibers. Wash cold, gentle cycle, inside out. Air dry or low heat only. Use Tide Free & Gentle as your detergent and Downy Rinse instead of softener. For persistent odor, add OxiClean to break down the residue at the source.
