10 Best Detergent For Wool Sweaters 2026 in the United States

The Laundress Delicate Wash is a double-concentrated detergent designed primarily for delicate fabrics such as silk and lingerie. It has a gentle formulation, making it potentially suitable for wool sweaters, given it is enzyme-free, which is beneficial for wool as enzymes can damage natural fibers. However, the product does not specifically mention lanolin content, which is ideal for maintaining the softness and integrity of wool.

The detergent is scented with a 'Lady' fragrance, a citrus and floral blend, which might not be suitable for those who prefer fragrance-free or ultra-mild options for wool garments. On a positive note, the detergent is phosphate-free and made from bio-based, eco-friendly ingredients, adhering to environmentally conscious standards. The double concentration means it offers good value, providing up to 31 loads from a 16-ounce bottle, although users should take care with dosing to avoid overuse.

Its transparent and lightweight consistency is designed to minimize mess, though it requires an additional measuring cup, which is not included. This detergent is well-suited for consumers looking for a versatile, eco-friendly option for general delicate fabrics, but those specifically seeking a detergent tailored for wool sweaters should consider whether the fragrance and lack of lanolin meet their needs.

The Laundress Wool & Cashmere Shampoo is a concentrated detergent designed specifically for delicate fabrics like wool, cashmere, merino, and mohair. One of its main strengths is the updated double-concentrated formula, which is made from bio-based ingredients, making it more eco-friendly. This concentration means you get 31 laundry loads from a single 16oz bottle, making it quite economical. The liquid form has a lightweight consistency, which helps in less messy dosing, though you will need to purchase a separate measuring cup for precise dosing.

The detergent is phosphate-free, aligning well with eco-friendly considerations. It also features a cedar scent, which is a modern twist on a traditional woodsy fragrance. This might appeal to some users, although those who prefer fragrance-free detergents might find this a drawback. Additionally, the cedar scent is designed to be softer for a gentler clean, which is a positive for those with sensitive noses.

The enzyme-free formula is a plus as enzymes can be harsh on wool fibers. Lastly, it’s made in the USA and is a top seller in the Health & Household category, which speaks to its popularity and reliability. This detergent is a good choice for individuals looking to care for their woolen garments with an eco-friendly and effective cleaning solution, provided they don't mind the cedar fragrance.

Eucalan Fine Fabric Wash in Eucalyptus scent is a strong choice for washing wool sweaters, especially if you prefer a gentle, eco-friendly option. It’s enzyme-free, which is important because enzymes can break down wool fibers, so this helps keep your sweaters in good shape. The detergent contains lanolin, a natural wool grease that acts like a conditioner, helping to keep wool soft and less prone to damage. It is concentrated, meaning you only need to use a small amount per wash, which can make the bottle last longer and is better for the environment.

Speaking of which, it’s biodegradable and non-toxic, so it’s safer for you and the planet. The eucalyptus scent is mild but noticeable, so if you’re sensitive to fragrance, that’s something to keep in mind. The product works well for both handwashing and machine washing delicate wool items. If you need a completely fragrance-free detergent, this might not be perfect.

This detergent is well-suited for anyone wanting a gentle, effective, and eco-friendly option to care for wool sweaters, with some added benefits from lanolin and a mild natural scent.
