Cashmere and Wool Care in Houston: How to Wash, Store, and Protect Fine Knits

Cashmere and Wool Care in Houston: How to Wash, Store, and Protect Fine Knits

Houston's winters are brief — a few cold fronts between November and February, some damp miserable days in January, and then it's 80 degrees again by March. But brief doesn't mean unimportant. A good cashmere sweater, a merino wool blazer, or a fine-knit turtleneck can last fifteen years if cared for properly. Mishandle one and you've lost a significant investment in a single wash cycle.

Here's what you need to know about caring for wool and cashmere in Houston's climate — including the long hot storage stretch that most cities don't have to think about.

Can You Wash Cashmere at Home?

Sometimes, yes — but it's riskier than most people realize. Cashmere is a protein fiber (like hair), and heat plus agitation cause it to felt: the fibers mat together permanently, shrinking the garment and giving it a fuzzy, matted appearance that cannot be reversed.

If you attempt home washing:

• Use cool water only — never warm, never hot
• Use a wool-specific detergent or baby shampoo (not regular detergent)
• Soak briefly, then gently squeeze — do not rub, wring, or twist
• Roll in a clean towel to remove moisture, then lay flat on a dry towel to air dry
• Never hang cashmere to dry — it stretches under its own weight
• Never put cashmere in the dryer, not even on air-only setting

For heavily soiled cashmere, fine beading, embroidery, or anything labeled 'dry clean only,' skip the sink entirely. The risk of irreversible damage isn't worth the cost savings.

When to Dry Clean Wool

Most structured wool garments — blazers, sport coats, wool trousers, tailored skirts — should be dry cleaned rather than washed at home. Structure is built into these garments with interfacing and pressing that water washing destroys. Even if the fabric itself survives, the shape won't.

Dry cleaning intervals:

• Tailored wool suits and blazers: Once or twice per season, or when visibly soiled
• Casual wool knits: After 3-5 wearings, or when odor develops
• Cashmere: After every 3-5 wearings if worn against the skin; less often if worn over other layers
• End of season (critical): Always dry clean before long-term storage — body oils and invisible food residue attract moths

The Houston Storage Problem

Houston's climate creates a storage challenge most northerners don't face: your wool and cashmere may spend 8+ months in storage between Houston's brief cool seasons. During those months, two threats emerge — moths and mildew.

Moths are the bigger risk. They don't eat clean fabric; they're attracted to the protein residue from body oils, sweat, and food stains that remain on unwashed garments. This is why dry cleaning before storage is non-negotiable for natural fibers.

After cleaning:

• Store in breathable garment bags (not airtight plastic — wool needs airflow)
• Add cedar blocks, cedar balls, or lavender sachets to deter moths
• Avoid mothballs if possible — the chemical odor is extremely difficult to remove from fabric
• Store in a climate-controlled space; the garage is not appropriate for fine wool

Mildew is the secondary risk. Wool stored slightly damp in Houston's humidity will develop mold. Ensure garments are completely dry before storage, and check on them once mid-summer.

Pilling: Causes and Solutions

Pilling is surface friction that causes short fibers to ball up. It's most common at friction points: underarms, sides, and anywhere a bag strap rides. It's not a defect — even high-quality cashmere pills. A fabric shaver or sweater comb removes pills easily and restores the look of the garment. Work gently on cashmere and go with the grain of the fabric.
