1. Robijn Wool & Fine – Reliable classic

The best choice for general use. Almost everyone knows Robijn—it's been a household name for years. Robijn Specials Wool & Delicates is their liquid detergent specifically for delicates. It scores highly for fiber protection. We find that woolen clothes washed with Robijn remain wonderfully soft. Robijn Wool & Delicates is pH-neutral and enzyme-free, so it's safe for wool. It also leaves a subtle, fresh scent that's characteristic of Robijn.

Pros: Easily available (supermarkets and drugstores), pleasant scent, formulas with fiber protectors that prevent frizz. Robijn claims to use biodegradable ingredients, which is a bonus.

Potential drawbacks: It's not the cheapest detergent. It also comes in a plastic bottle – a drawback for those who want to live plastic-free. It also contains perfume, which is pleasant for most people, but less suitable if you have very sensitive skin.

Our experience: Robijn Wool & Fine delivers what it promises. Wool comes out clean and soft, without shrinkage (provided you follow the washing instructions, of course). It's a safe feeling to use this classic for your finest sweaters. No frills, just good.

2. Woolite Wool & Silk – Extra caring with keratin

The best choice for luxury fabrics. Woolite is a brand synonymous with delicate laundry worldwide. Their Wool & Silk detergent is designed to clean both animal fibers (wool, silk, cashmere) and synthetic delicate fabrics. What makes Woolite so special is that it often adds extra keratin or proteins to the formula. That sounds strange—aren't stains partly made of protein, too?—but these ingredients create a microscopic layer on the fibers, making them feel smoother and less likely to damage. It helps keep that beautiful cashmere sweater in shape.

Pros: Woolite Wool & Silk is very mild and virtually odorless. It contains no bleach and is, of course, enzyme-free. Keratin in the detergent is said to strengthen the fibers (keratin is the protein wool itself is made of). Many users swear by it for silk blouses and wool scarves.

Potential drawbacks: In the Netherlands, Woolite is somewhat less readily available, but it's usually available at larger supermarkets or online. The price per wash is relatively high. And while the keratin is a nice selling point, it's difficult to measure how much difference it makes in practice.

Our experience: This detergent leaves wool clothing feeling incredibly soft. You'll notice the material doesn't dry out. Especially with a wool cardigan that one of our testers wears frequently, we noticed fewer lint balls after a few washes with Woolite compared to a generic detergent. An excellent choice, especially if you have more expensive garments that require extra care.

3. Soap Wool & Fine – Natural & sustainable

The best choice for environmentally conscious laundry users. Seepje is a Dutch brand that makes sustainable laundry detergents, known for their super peels (natural soap fruits). Their Wool and Delicate detergent is completely plant-based and not tested on animals. The active ingredient is often saponin from plant extracts, which ensures gentle cleaning. Seepje wool detergent has a light scent of natural essences (for example, "Happy Lotus" is a popular variant at maakjouwkeuze.nl). It contains no synthetic additives—so no dyes, optical brighteners, or enzymes.

Pros: Very friendly to the environment and your clothes. The bottles are made of recycled plastic and also look great in your laundry room. Seepje wool detergent keeps wool fibers supple; lanolin is better preserved because it doesn't contain any harsh chemicals. Also great: sensitive skin or allergies? Seepje is hypoallergenic.

Potential drawbacks: Seepje is a bit more expensive than mainstream brands. You also sometimes have to order it if you can't find it in a store nearby. The cleaning power is excellent, although it might be a little less powerful than chemical products for heavy stains – it's a conscious trade-off for gentleness.

Our experience: We're thrilled with Seepje. A wool blanket that had a faint sweat odor emerged wonderfully fresh and soft after washing with Seepje Wool & Fine, without an overpowering perfume. The idea that it's all natural is reassuring. It works perfectly for standard dirt and odors. For a really stubborn stain on a wool sock, we did have to pre-treat it (with ox gall soap, another natural trick). But for regular use: very satisfied!

4. Sonett Wool Detergent – ​​Organic and super soft

The best choice for ultimate softness. Sonett is a German eco-brand that produces high-quality organic laundry and cleaning products. Their liquid Wool and Silk Detergent is based on pure olive soap and sugar-tenzides, enriched with ingredients like olive oil extract. maakjouwkeuze.nl. This detergent is completely biodegradable. Interestingly, olive soap is a time-honored method for cleaning delicate fabrics, especially popular in Southern Europe for wool and lingerie. Sonett has a subtle natural fragrance (e.g., lavender and lemongrass oil).

Pros: Completely enzyme-free, fragrance-free (only natural essential oils), and preservative-free. This is ideal for people with allergies or extremely sensitive skin. It washes wool very gently, preserves the lanolin, and prevents felting. Also nice: it's concentrated; you only need a small amount per wash.

Potential drawbacks: Olive soap may foam less and feels different from regular detergents – it takes some getting used to. It's not dirt cheap. And be aware: because it's so gentle, it's really meant for wool and silk. This product isn't powerful enough for dirty jeans, but of course, it's not meant for that.

Our experience: For hand-washing a delicate wool cardigan, Sonett proved fantastic. The cardigan smelled clean and felt buttery soft after drying. No pungent odors, just a hint of lavender. We noticed that colors stayed beautifully vibrant and the fabric didn't dry out at all. Sonett may be a little less well-known, but within the eco-conscious world, it's a real winner for your wool and delicates.

(Other products worth mentioning: Eucalan (no-rinse wool detergent, popular with knitters), and Essential wool detergent (a house brand that also gets good reviews). But with the top 4 above, you really can't go wrong.)

Frequently asked questions about wool detergents

Which wool detergent is best for cashmere sweaters?

Cashmere is even finer than regular wool. In our experience, Woolite Wool & Silk is very suitable for cashmere because of the extra fiber protection (keratin) it provides. Sonett also scores well because it's so gentle. The most important thing is that it's enzyme-free and pH-neutral – Woolite, Sonett, and Seepje all meet these requirements. Robijn Wool & Fine is also fine, but if you're particularly careful with expensive cashmere, choose a specialized eco-friendly product or Woolite.

Does expensive vs. cheap matter when it comes to wool detergent?

To a certain extent. More expensive (often ecological) wool detergents like Seepje and Sonett use high-quality, natural ingredients and avoid all unnecessary additives. This is better for the environment and potentially better for your clothes in the long run. However, affordable options like Robijn also perform well and have been extensively tested for results. If you wash a lot of wool frequently, you can invest in an eco-brand for peace of mind. For the occasional wool scarf, a decent mid-range product like Robijn or Woolite will also suffice.

Can't I just add a dash of vinegar or fabric softener to regular wool detergent?

We advise against this. Vinegar is fine as a rinse aid, but it doesn't make regular detergent any more wool-friendly – ​​it retains the enzymes that can damage wool. You shouldn't use fabric softener on wool at all. Wool is already soft (especially with a good detergent); fabric softener can leave a film that reduces its breathability. Moreover, many fabric softeners contain perfumes and substances that are actually harmful to the delicate wool fibers. Instead, invest in a good wool detergent; that's the best "softener" you can have for your wool.

Are there sustainable alternatives to liquid wool detergent?

Absolutely! Besides the Seepje and Sonett mentioned here (both of which are sustainable in terms of ingredients), you can also look at innovative options. For example, laundry detergent strips – they are highly concentrated, plastic-free, and gentle. Our Simplewas laundry strips contain no enzymes or bleach, so you can use them for wool too. There are also soap nuts or soap shells that create a natural lather; some people wash wool with them in a laundry bag. The bottom line is that there are plenty of alternatives that are less harmful to the environment. As long as they are gentle and enzyme-free, your wool sweaters will be happy with them!
