Most laundry detergent sheets and detergents are made for regular laundry. This means they're often not suitable for delicate fabrics like wool. Wool is a natural fiber and needs a little extra care because it can shrink or get damaged pretty quickly if you use harsh cleaning products. We'll talk about the best way to wash your wool sweater and give you some tips to keep your wool clothes looking great (like using wool detergent).

Why is wool detergent better for wool and delicate fabrics?

Regular laundry detergent sheets are designed to remove stubborn dirt and stains from frequently used fabrics like cotton and synthetics. This means detergent isn't always suitable for washing wool and other delicate fabrics. That's because of the specific ingredients found in detergent. 

Take for example Sodium Coco-Sulfate, a foaming cleanser that removes dirt well, but can also affect the natural oils in wool fibers. These oils are actually important to keep wool soft and elastic. Without these oils, wool becomes dry and stiff.

In addition, laundry detergent sheets contain enzymes like Protease, which are designed to break down protein stains like blood and sweat. However, wool is also a protein, namely keratin, similar to human hair. Protease can therefore break down the wool fibers, which can weaken and damage the material. 

Another enzyme, Cellulase which is meant to smooth cotton fibers, offers no benefits for wool and can even cause unwanted wear, since wool doesn't contain cellulose.

Furthermore, fabrics such as Trisodium Citrate and Citric Acid Monohydrate in laundry detergent sheets designed to balance the pH and boost cleaning power. However, wool needs a slightly acidic pH to keep its fibers in top shape. If the detergent has too high a pH, it can damage the wool. 

In addition, the fragrances the ones added to laundry detergent sheets make your clothes smell great, but they're not always good for wool. These fragrances can cause irritation to the delicate wool fibers. And when perfume residues build up in the wool fibers, your sweater becomes less airy. 

These are all things to keep in mind if you want to keep your woolen clothes soft and comfy.

What happens to wool when you use regular laundry detergent sheets or detergent?

If you use regular laundry detergent sheets or detergent to wash woolen clothes, several issues can arise that affect the quality of the wool. First of all, wool can shrink; this happens due to chemical reactions and using the wrong temperatures during washing. In addition, wool can felting, which means that the protective structure of the fibers breaks down. This is often caused by rough handling and the fibers rubbing against each other during washing. Wool can also stiff and brittle This happens because the natural oils that keep the wool soft and supple are removed. 

What’s the best thing to use for wool clothing?

For washing your woolen clothes, it's best to choose a mild wool detergent. There are also laundry detergent sheets available that are perfect for delicate fabrics and wool, such as the wool & silk laundry detergent sheets from Cosmeau. With a low temperature wool wash program, your woolen clothes stay beautiful, soft, and clean.

Always check the packaging of a detergent to make sure it's suitable for wool. If you want to be extra careful, you can also use baby shampoo for hand washing—it's gentle on the fabric and works similarly to a wool detergent. Wash in lukewarm water, avoid wringing, and let the garment dry flat.

Regular laundry detergent sheets are super convenient for everyday laundry, but they can be harsh on delicate fabrics like wool. Ingredients such as sodium coco-sulfate, protease, and fragrance just aren’t suitable for caring for these natural fibers. That’s why it’s always best to choose a detergent specially made for delicate fabrics, so your woolen clothes stay looking great.
