Learn the correct way to hand wash cashmere and wool at home using a gentle shampoo. Follow these steps to keep your knits soft, clean, and free of damage.
Quick Answer
To wash wool and cashmere at home, use a dedicated wool cashmere shampoo like The Laundress's formula, hand wash in cool water, and lay flat to dry. Avoid wringing or hanging to prevent stretching and damage.
Why Use a Dedicated Shampoo for Wool and Cashmere
Regular detergents contain enzymes and brighteners that can break down animal fibers, causing them to felt or lose their softness. A dedicated wool cashmere shampoo is pH-balanced and free of dyes and brighteners, making it safe for delicate materials.
The Laundress Wool & Cashmere Shampoo is formulated specifically for wool, cashmere, merino, mohair, and blends. It also carries a soft Cedar fragrance with notes of bergamot, rosewood, and sandalwood, so your knitwear comes out smelling fresh without harsh chemicals.
When to Hand Wash vs. Machine Wash
Hand washing is the gentlest method and gives you full control over water temperature and agitation. It’s the best choice for heavily soiled items or when you want to minimize stress on the fibers.
Some wool garments can be machine washed on a delicate cycle, but this requires a mesh bag and cold water. However, even with a gentle cycle, machine washing can cause more abrasion and is riskier for delicate knits. When in doubt, hand wash.
Always check the care label first. If it says dry clean only, follow that instruction instead of washing at home.
Steps to Hand Wash Wool and Cashmere at Home
- Pre-treat stains: Apply a small amount of wool cashmere shampoo directly to any stains and gently rub with your fingers. Let it sit for 5 minutes before washing. Test on an inconspicuous area first to ensure the color doesn't bleed.
- Fill a basin with cool water: Use a clean sink or basin filled with cool water (below 30°C/85°F). Add the recommended amount of shampoo (about 2 caps for a medium load) and swish to distribute. Hot water can shrink wool and cashmere, so always keep it cool.
- Submerge and gently squeeze: Place the garment in the water and gently press it down to saturate. Avoid rubbing or scrubbing, which can cause felting. Let it soak for up to 30 minutes for light cleaning. Never twist or wring the fabric—this distorts the fibers.
- Rinse with cool water: Drain the soapy water and refill the basin with clean cool water. Gently press the garment to release soap, then repeat until the water runs clear. Residual shampoo can attract dirt, so rinse thoroughly.
- Remove excess water: Lift the garment out and gently press it against the side of the basin to remove excess water. Then roll it in a clean, dry towel to absorb moisture. Do not wring or twist—this can stretch the fibers permanently.
- Dry flat on a towel: Lay the garment flat on a dry towel, reshaping it to its original dimensions. Keep it away from direct sunlight and heat sources. Allow it to dry completely before wearing or storing. Hanging wet wool or cashmere can cause it to stretch out of shape.
