Washing Underwire Bras the Right Way: A Professional Lingerie Care Guide
Introduction: Why Proper Bra Care Matters
When it comes to intimate apparel, few garments combine function and femininity like the underwire bra. But even the best-fitting bra can quickly lose its shape and support if it isn’t cared for properly. That’s why knowing how to wash underwire bras is essential — not just for personal comfort, but for garment longevity.
At Xinxu Underwear Accessory (HK), we’ve been working with top global lingerie brands since 1995. We understand the science behind bra structure and the materials that make them last. This article shares expert-backed advice, based on industry experience and product knowledge, to help you care for your underwire bras the right way.
The Structure Behind the Bra: Why Underwires Need Special Treatment
Underwire bras contain metal components, elastic fabrics, and delicate trims that require gentle handling. If mistreated, the underwire can bend, break through fabric, or lose its curvature — leading to discomfort or even skin injury.
From an engineering standpoint, a bra’s performance depends on the integrity of its components — including the underwire, which Xinxu manufactures using OEKO-TEX® certified stainless steel and subjects to salt spray and needle detection tests to ensure safety and durability.
Step-by-Step: How to Wash Underwire Bras Like a Pro
1. Check the Care Label First
Each fabric blend reacts differently to washing. Always check for symbols indicating hand wash only, temperature limits, or drying methods.
2. Hand Washing: The Gold Standard in Lingerie Care
Professional lingerie care guides always recommend hand washing:
- Fill a basin with lukewarm water
- Add a mild detergent made for delicates
- Soak your bra for 10–15 minutes
- Gently press the bra — never scrub or twist
- Rinse in cold water to preserve elasticity
💡 Expert Tip from Xinxu:
If your underwire was made with high-resistance coating (like those from our Nylon Coated Collection), it will hold up better against mild detergents and everyday wear — but still benefits from hand washing.
3. If Using a Washing Machine: Protect the Structure
- Place bra in a mesh lingerie bag
- Hook clasps to avoid snags
- Use cold water and the “delicate” cycle
- Avoid washing with heavy fabrics
4. Drying: Never Use Heat
- Never tumble dry — heat damages both metal and elastic
- Lay the bra flat on a towel or dry it by hanging from the center gore (never the straps)
How Often Should You Wash Your Underwire Bra?
Lingerie experts recommend washing after 2–3 wears. Frequent washing isn’t always necessary — unless you’ve been sweating or wearing perfume/lotion that may degrade the fabric.
Rotating your bras between wears allows elastic to recover, maintaining stretch and fit longer.
Storage Best Practices from Lingerie Manufacturers
Improper storage can warp cups and stretch the band.
Here’s what we advise at Xinxu:
- Stack bras flat, cup-to-cup (not folded into each other)
- Don’t squish bras under heavier items
- Store in a dedicated lingerie drawer or organizer
🛠️ Our plastic bones and rim wires are made to be shape-retaining — but they still need proper care during storage to perform at their best.
What to Avoid (According to Industry Standards)
- Avoid these common mistakes:
- Hot water or bleach
- Fabric softeners (can degrade elastic)
- Twisting or wringing
- Machine drying
- Hanging by straps
