The Complete Guide to Sweater and Wool Coat Care

From hand-washing cashmere to proper storage, here is how to keep your wool sweaters and coats looking refined season after season.

Many wool sweaters can be washed at home if you take a gentle approach. Turn the garment inside out and use a wool-specific detergent in cool or lukewarm water. Hand-washing is ideal, but if you prefer a machine, use the wool or delicate cycle with a mesh laundry bag and minimal spin speed.

Can you wash wool sweaters in a washing machine? Yes, provided the care label confirms it is machine-washable and you use a gentle, low-agitation cycle. Avoid wringing or twisting the fabric. For cashmere specifically, always hand-wash when possible, use lukewarm water only, and reshape the garment immediately after washing while it retains moisture.

Wool coats endure daily wear, so simple habits extend their life between professional cleanings. Brush the fabric regularly with a soft-bristled clothes brush to lift surface dust and prevent it from embedding in the fibers. Air out your coat after each wear rather than hanging it directly in a crowded closet.

How often should a wool coat be dry cleaned? Most wool coats only need professional dry cleaning once or twice per season, unless visibly soiled or stained. Over-cleaning can strip natural oils from the fibers, so spot-treating minor marks and brushing regularly is often sufficient in between visits.

Treat stains on wool promptly, but avoid rubbing, which can damage fibers and spread the mark. Blot liquid spills with a clean, absorbent cloth and address the area with a small amount of cold water or a wool-safe stain solution before it sets.

For wool coat stain removal, resist the urge to apply household stain removers not formulated for delicate fabrics, as many contain harsh chemicals that discolor or weaken wool. Odors typically lift with fresh air exposure, but persistent smells or stubborn marks are best left to professional dry cleaning, where solvent-based methods clean thoroughly without compromising the fabric.

Never hang wool sweaters to dry, as the fabric's weight will stretch and distort the shape permanently. Instead, lay the garment flat on a clean towel, gently reshape it to its original dimensions, and allow it to air dry away from direct sunlight or heat sources.

Wool coats should be hung on a sturdy, shaped wooden hanger in a well-ventilated area after cleaning or exposure to rain. Avoid radiators, direct sun, and tumble dryers entirely, as heat accelerates fiber damage and shrinkage in both sweaters and coats.

Proper storage protects wool from moths, moisture, and shape loss during warmer months. Clean garments thoroughly before storing, since residual oils and food particles attract pests. Fold sweaters rather than hanging them, and store them in breathable cotton garment bags rather than sealed plastic, which can trap moisture.

Wool coats should hang on padded or wooden hangers with enough space to maintain their shape. Add cedar blocks or lavender sachets to deter moths naturally, and choose a cool, dry, dark storage area away from direct light exposure.
