How to wash and care for wool and cashmere: a guide for delicate garments

Wool and cashmere are delicate fibers that can be preserved for a long time if washed and dried correctly. Not all garments require the same treatment: the manufacturer's label is always the primary reference.

In this guide, we explain how to wash wool and cashmere garments, when to do so, what soap to use, how to remove excess water, and how to dry and store them to prevent deformation.

How often should wool and cashmere be washed?

It is not necessary to wash a wool or cashmere sweater after every use. The frequency depends on use, contact with the skin, sweat, and the garment's instructions. Between washes, let the garment air out and ensure it is completely dry before storing it.

If the garment shows no signs of dirt or odor, airing it out may be sufficient between uses. If it is stained, damp, or has accumulated sweat, it is best to clean it following its care instructions.

Before washing a wool or cashmere garment

• Read the label and check if it is suitable for hand or machine washing.
• Identify the maximum temperature and drying instructions.
• Separate colors and close zippers or other elements that may cause friction.
• If the garment allows, turn it inside out to reduce friction during washing.
• Treat stains locally using a product compatible with the fiber.

How to wash wool and cashmere in the washing machine

If the label allows machine washing, use the specific program for wool or delicate garments and respect the indicated temperature. There is no universal temperature for all sweaters: some handle 30°C, while others require different treatment.

• Use a wool or delicate cycle.
• Choose the temperature indicated on the label.
• Use a moderate dose of soap suitable for the fiber.
• Avoid overloading the drum.
• Select a spin cycle compatible with the program and the label.

A mesh laundry bag can be useful if the manufacturer recommends it or if you want to reduce contact with other garments. Do not put a garment in the washing machine just because it is made of wool: the construction, finishes, and label also determine how it should be washed.

How to hand wash wool and cashmere

When the label indicates hand washing, fill a basin with water at the recommended temperature and pre-dissolve a small amount of suitable soap. Place the garment in and move it gently so that the water and soap pass through the fibers.

Do not scrub hard or wring out the fabric. After washing, rinse with clean water until all soap residue is removed. Avoid sudden temperature changes, especially with wool garments.

To remove some of the water, press the garment gently. You can also wrap it in a clean towel and press without wringing.

What soap should be used for wool and cashmere?

Choose a laundry product indicated for wool, cashmere, or delicate garments and respect the recommended dosage. At Home Healthy Home, you can use our No. 13 laundry soap for silk and wool, formulated for these types of garments.

Do not automatically use a conventional detergent just because a garment seems sturdy. When in doubt, follow the instructions from both the garment manufacturer and the laundry product.

How to dry wool and cashmere without deforming them

Drying is one of the most important stages. For many wool and cashmere garments, the safest option is to dry flat on a clean towel or a suitable surface, gently reshaping the garment.

• Do not wring the sweater to drain it.
• Avoid radiators and intense heat sources.
• Avoid direct sunlight if the label or the garment's color advises against it.
• Do not hang a wet garment if it may deform.
• Check the label before using a tumble dryer.

The wool dryer balls should only be used in a tumble dryer when the garment label permits this drying method.

Can wool and cashmere be dry cleaned?

If the label indicates professional cleaning or dry clean only, follow that instruction. It is not advisable to replace it with hand washing on your own initiative, as a garment may have linings, finishes, or a construction that does not tolerate water.

If the label allows home washing, choose the method indicated for that garment. You can also consult our guide for hand washing clothes.

How to prevent pilling on wool

Pilling can occur due to friction and use; it does not necessarily mean the garment is damaged. To reduce wear, avoid unnecessary friction during washing and store the garment correctly.

If pills appear, you can remove them with a suitable accessory for delicate fabrics, working gently without pulling the fibers.

How to remove stains from wool and cashmere

Act as soon as possible, but avoid rubbing. First, remove the excess stain and check the label before applying water or a stain remover. For difficult stains or high-value garments, consult the manufacturer or a professional textile cleaner.

How to store wool and cashmere sweaters

Before storing them, ensure they are clean and completely dry. For many knit garments, it is preferable to store them folded instead of hanging them, as the weight can cause them to lose their shape.

Store them in a clean, dry, and ventilated space. To protect them from moths, you can check our cedar moth-repellent rings and follow the closet storage recommendations.

Common mistakes in wool and cashmere care

• Washing at a temperature higher than indicated.
• Using a program that is too intense.
• Rubbing or wringing the fabric.
• Using too much soap.
• Drying a wet garment hanging when it might deform.
• Applying intense heat to speed up drying.
• Ignoring professional cleaning instructions on the label.
