Quick Answer

To preserve the softness and mineral benefits of your underwear, hand wash in cold water with a gentle detergent, or use the delicate cycle in a mesh bag. Always air dry away from direct heat. Avoid fabric softeners and bleach, as they can break down the zinc oxide lining.

Mineral-infused underwear, like the styles from Huha, uses TENCEL fibers and a zinc oxide lining to support comfort and breathability. To keep these features working, proper care is essential. Washing them wrong—like using hot water or a harsh dryer—can reduce the fabric's softness and the effectiveness of the mineral treatment.

This guide walks you through the best practices for washing mineral underwear, whether you prefer hand washing or machine washing, and how to dry them so they last longer and feel great every time you wear them.

Why Care for Mineral-Infused Underwear Differently?

Mineral-infused underwear often features a gusset or lining knitted with zinc oxide, which is intended to provide comfort and odor control. The TENCEL fibers are derived from trees and are known for their breathability and softness. These materials are more delicate than synthetic blends, so they need gentler handling to maintain their properties.

Using high heat, strong detergents, or fabric softeners can cause the fibers to break down faster and may reduce the mineral coating's longevity. By adjusting your washing routine, you can extend the life of your underwear and keep them feeling as good as new.

Choosing the Right Detergent

Opt for a mild, pH-neutral detergent that is free from bleach, optical brighteners, and enzymes. These harsh chemicals can strip the mineral treatment and cause irritation. Look for detergents labeled as gentle or suitable for delicates. Avoid fabric softeners and dryer sheets, as they leave a residue that can clog the fabric's breathability.

If you have sensitive skin, consider a detergent that is fragrance-free and hypoallergenic. Always follow the manufacturer's instructions for the correct amount to use, as too much detergent can leave buildup that affects the fabric's performance.

Step-by-Step Washing Instructions

  1. Step 1: Pre-treat stains: Check for any stains and gently dab with a mild detergent or a stain remover that's safe for delicates. Avoid rubbing, as this can damage the fibers. Checkpoint: Always test stain remover on a small, hidden area first to ensure it doesn't discolor the fabric.
  2. Step 2: Hand wash in cold water: Fill a basin with cold water and add a small amount of gentle detergent. Submerge the underwear and gently squeeze the fabric—do not wring or twist. Let them soak for 5-10 minutes, then rinse thoroughly with cold water until no soap remains. Checkpoint: Cold water is key; hot water can break down the mineral treatment and cause shrinking.
  3. Step 3: Machine wash on delicate cycle (alternative): If you prefer machine washing, place the underwear in a mesh laundry bag to protect them from snagging. Use the delicate or gentle cycle with cold water and a mild detergent. Avoid overloading the machine to allow proper cleaning. Checkpoint: Always use a mesh bag to prevent the underwear from getting tangled or stretched.
  4. Step 4: Rinse thoroughly: Ensure all detergent is rinsed out, as residue can cause irritation and reduce breathability. If hand washing, you may need to rinse twice. Checkpoint: Leftover detergent can leave a film that traps odor, so rinse until the water runs clear.
  5. Step 5: Dry flat or hang to air dry: Lay the underwear flat on a clean towel or hang them to dry in a shaded area. Avoid direct sunlight and never use a tumble dryer, as heat can damage the elastic and mineral lining. Checkpoint: Air drying is the safest way to preserve the fabric's softness and shape.
