Can you wash wool in the washing machine, or will it get ruined? Many people worry that their favorite wool sweater will shrink in the wash, but washing a wool sweater doesn’t have to be risky. While wool does require a little more care when washing, these six tips from bluu will help you wash your woolen garments easily and safely.
#1 Don't wash wool in water that's too hot
A wool sweater is one of the most comfortable pieces of clothing for everyday wear. It keeps you warm, is breathable, and feels soft against the skin. At the same time, however, wool is also one of the most delicate materials when it comes to washing. If you want to wash your wool sweater, you should therefore know what really matters.
Wool is a natural fiber made of keratin, just like our hair. Just like hair, wool consists of tiny scales that interlock when exposed to heat and movement. This process is called felting. Once these scales have interlocked, the material contracts and becomes smaller. This means that a wool sweater not only shrinks but also loses its elasticity. That’s exactly why it’s so important to be careful whenwashing wool and to avoid heat, vigorous rubbing, and harsh detergents.
That's why it's important to avoid using hot water when washing a wool sweater and make sure the water doesn’t exceed 30 degrees , whether you wash your woolen clothes in the washing machine or by hand.
#2 Washing a Wool Sweater in the Washing Machine
Many wool sweaters can be washed in the washing machine without any problems, provided you use a gentle cycle. Standard washing machine cycles are too harsh and can damage the fibers.
However, most washing machines have a wool cycle and/or a gentle wash cycle. This cycle reduces drum movement, uses plenty of water, and keeps the temperature consistently low. This prevents damage to the delicate fibers. This is the right choice for you, because wool should be washed as gently as possible to prevent the fabric from felting or stretching out of shape.
These programs use minimal agitation, plenty of water, and low temperatures, which are gentler on your wool. It’s important to turn your wool sweater inside out beforehand and, ideally, place it in a laundry bag. This reduces friction and protects the fibers.
- If possible, select the wool or delicate cycle
- Wool at 600 to a maximum of 800 revolutions wash
- If you're unsure, it's better to wash by hand

#3 Use bluu to wash wool
Wool—whether merino or cashmere—is a natural product that is very delicate.
When it comes to laundry detergent, it's important that it be free of enzymes and optical brighteners—wool doesn't tolerate them very well.
Our laundry strips are free of both and are ideal for your woolen clothes. They work just as well in the washing machine as they do for hand washing (by the way, you can find out how to wash by hand properly here.). And please skip the fabric softener!
#4 Treat stains gently
If your woolen clothing has a stain, a gentle approach is best here as well. Do not use harsh stain removers or rub the area vigorously.
Instead, dissolve some bluu laundry strips in water and gently dab the stain with the solution. You can also use a brush for this. Repeat the process if necessary. Ifthe stain is stubborn, you can repeat the process using bluu stain remover soap. Mix it with a little water and gently dab the area.
#5 As little as possible, as much as necessary
Especially when it comes to delicate wool, the rule is: the less you wash it, the better.
Did you know that wool can clean itself? That means you don’t necessarily need a wool detergent. The interior consists of two types of fibers, one of which absorbs more moisture than the other. This causes the fibers to rub against each other, thereby shedding dirt. The dirt doesn’t stick as well.
So if your wool clothes smell a little but are actually still clean, then hang them up to air them out.
Tip:
Wear a T-shirt under your wool sweater so that sweat isn't absorbed by the wool. This will keep the sweater fresh and fluffy for longer.
#6 Dry the wool sweater while it's lying flat
Wool takes a surprisingly long time to dry properly. And since you should only wash it on the delicate or wool cycle (with a low spin speed), the clothes will be quite wet. That’s why it’s important to keep the following in mind:
- Never wring out wool!
- Place your woolen clothes on a towel, roll it up, and gently squeeze out the excess water.
- It's best to , dry your wool flat on a clothes rack.
- It's It’s best not to hang up wool—that stretches the fibers and causes your clothes to lose their shape.
