Keep mineral-infused underwear fresh and long-lasting with a straightforward washing routine that covers sorting, machine vs. hand washing, drying, and storage.
Quick answer
Wash mineral-infused underwear in cold water on a delicate cycle or by hand, using a small amount of mild detergent. Avoid fabric softener, bleach, and high heat. Air-dry flat or hang to protect the TENCEL™ fibers and antimicrobial zinc oxide. This routine keeps your undies fresh and extends their lifespan.
Sort by fabric and color first
Separate mineral-infused pieces from heavy items like jeans or towels that can cause friction and pilling. Wash light and dark colors separately to prevent dye transfer. If you own both Mineral Undies and Mineral Bottoms, you can wash them together as long as colors are similar and you use a gentle cycle.
Choose the right wash method
For everyday freshness, a machine wash on delicate with cold water is fine. Use a mesh laundry bag to prevent stretching and snags. If your machine has an agitator, consider hand washing instead. Hand washing is also better for very delicate styles like the Low Profile Thong, where the zig zag stitch and sleek fabric benefit from minimal agitation.
Use the right detergent and amount
Mild, liquid detergent without enzymes or bleach is safest. Too much detergent leaves residue that can irritate skin and dull the fabric. For hand washing, a pea-sized drop is enough for one or two pieces. For machine washing, fill the detergent cup only to the lowest line.
Drying without heat damage
High heat breaks down TENCEL™ fibers and can reduce the effectiveness of zinc oxide. Always air-dry. Lay flat on a towel or hang on a drying rack away from direct sunlight. If you must use a dryer, choose the lowest heat setting and remove items while slightly damp.
Store clean and dry
Make sure items are completely dry before folding and storing. Dampness encourages mildew and odors. Store in a cool, dry drawer. Avoid cramming them into tight spaces that can distort waistbands and leg openings.
Your 5-step mineral underwear washing routine
- Step 1: Pre-treat stains: Apply a tiny amount of mild detergent directly to stains and let sit for 5 minutes. Do not rub aggressively, as this can damage fibers. Checkpoint: Stains should be gently dabbed, not scrubbed.
- Step 2: Wash in cold water: Machine wash on delicate with like colors, or hand wash in cool water with a drop of mild detergent. Avoid hot water, which can shrink or degrade the fabric. Common mistake: Using hot water or regular cycle, which causes pilling and shrinkage.
- Step 3: Skip fabric softener: Fabric softener coats fibers and reduces breathability and antimicrobial properties. If you want softness, add a half-cup of white vinegar to the rinse cycle instead. Checkpoint: Softener is never needed and can harm performance.
- Step 4: Air-dry flat or hang: Lay flat on a clean towel or hang on a rack. Avoid direct sunlight and high heat. If using a dryer, use the lowest heat setting and remove while slightly damp. Common mistake: Tossing in a hot dryer, which breaks down TENCEL™ and zinc oxide.
- Step 5: Store completely dry: Ensure items are bone-dry before folding and storing. Keep in a cool, dry place away from direct heat sources. Checkpoint: Any dampness leads to mildew and odor.
Product care notes
- Long Boxer: Made with ultra-breathable TENCEL™ fibers and knitted with antimicrobial zinc oxide. These fibers and treatment are sensitive to high heat and harsh chemicals, so cold washing and air drying help maintain breathability and odor protection.
- Cheeky: Features a cuffed waistband and visible front panel, made with super-soft TENCEL™ fibers and a full-coverage gusset knit with antimicrobial zinc oxide. The cuffed waistband can lose shape in hot water; cold washing and flat drying preserve the fit and the gusset's functionality.
- Low Profile Thong: Lined throughout and secured with a flexible zig zag stitch, made with tree-derived TENCEL™ fibers and a full-coverage gusset knitted with zinc oxide. The zig zag stitch is prone to snagging, so use a mesh bag or hand wash to prevent pulls and extend the life of the thong.
