If you notice those tell-tale dark spots or a musty smell, follow these steps as soon as possible to neutralize the fungi and prevent further spreading.
Phase 1: The Salt Soak
The goal here is to kill the active mildew spores using a natural abrasive and desiccant.
Prepare the Solution: Mix 2 cups of salt into 1 gallon of warm water.
Soak: Submerge the affected area of the garment.
Scrub: Use a soft-bristle brush to gently scrub the mildew spots while the fabric is wet.
Rinse & Dry: Rinse thoroughly with fresh water and hang it in a well-ventilated area until completely dry.
Phase 2: The Deep Clean
Once the initial spores are neutralized, you need to clean the fabric.
Hand Wash: Use an antibacterial soap or a mild liquid detergent (avoid bleach or harsh industrial cleaners) mixed with warm water.
Final Rinse: Rinse with clean, fresh water until all soap residue is gone.
Air Dry: Hang to dry in a shaded, well-ventilated area. Never use a machine dryer or direct heat.
Mildew Prevention Tips
To keep your gear fresh for the long term, follow these storage "Golden Rules":
Dry Before Stowage: Never toss a damp jacket into a gear bag or a boat locker.
Ventilation is Key: Mildew thrives in stagnant, humid air. If you live in a high-humidity climate, consider using a dehumidifier in your gear storage room.
Freshwater Rinse: After every salt-water outing, rinse your gear. Salt is "hygroscopic," meaning it attracts moisture from the air, which creates a perfect breeding ground for mildew.
