Machine wash wool clothes on wool program

The right laundry bag and gentle spin for garments that keep their shape

Wool is great, but it scares many people in the laundry room. Maybe you've seen a favorite sweater shrink, nap or lose its shape. This happens when wool, which is a protein fiber with scales and natural fat (lanolin), is exposed to too much heat, wrong movements or the wrong detergent.

When the scales on the fibers catch on each other, the fabric can felt and shrink when washing wool. When the temperature goes up, or when enzyme-heavy detergents are used, the fibers break down and the surface becomes rough. The good news is that you can avoid these problems with one simple method: choose the right wool program, use the right laundry bag, and spin briefly and gently, followed by smart aftercare.

Wool program in washing machine: how it works and when to use it

The wool program is developed for delicate garments and makes it possible to machine wash wool safely. It works at low temperature, often cold to 30 degrees. The drum moves gently and pauses longer in this gentle program. The water stays still longer, providing gentle soaking. The spin at the end is short and gentle.
All this reduces friction and heat. The result is less risk of felting and shrinkage. The machine does not stress the fibers, but lets the dirt drop without violent mechanics.

When wool programs are the right choice:

• Light dirt, everyday freshness and odor.
• Garments without delicate details.
• When the label says wool program or hand wash.

When you choose hand washing or dry cleaning:

• Heavy soiling or stains that require a lot of rubbing.
• Delicate decorations, tassels, loose knitting or poor color fastness.
• Very expensive or sentimental garment where minimum risk should be avoided.

Newer machines often have adjustable speed, low water level and sensor-controlled drum. This helps the wool. Whatever the machine, always use enzyme-free detergent and a low dose.

Choose the right wool detergent: enzyme-free, mild pH and low dose

Enzymes break down protein, and wool is a protein fiber. Therefore, the detergent should be enzyme-free and preferably fragrance-free. A good detergent for wool is one that is completely enzyme-free. Fabric softener should never be used, as it can settle on the fibers and weigh them down.

• Use a small dose, often half of what the package says for light soiling.
• Lanolin-rich agents can preserve softness and fullness.
• If your machine is dosing hard, dissolve liquid agent in a little water before filling. It reduces point loading.

Hand wash or machine, you decide?

Himalayan Wool products should be washed infrequently. Air them outside from time to time to reduce the number of washes. When it is needed, you decide whether you want to machine wash on a wool program or wash wool by hand in cool water, perhaps in the sink. Choose what makes you feel safe and suits the garment.

The right laundry bag for wool garments: protect the fibers and keep their shape

A laundry bag acts as a soft barrier. It reduces friction, prevents the threads of the mesh from getting caught in the holes of the drum and keeps the garment more still. Less chafing means fewer knots and better shape.

Choose a fine, soft mesh with a hidden zipper or soft closure. Rounded corners reduce the risk of the bag twisting the garment. Size matters. Let the garment lie flat with some air around it, not compressed.

A simple trick: turn the garment inside out before putting it in the bag. This will protect the surface even more.

Material and size of laundry bag, what to choose?

• A fine-mesh, durable polyester or polyamide mesh works well.
  
• Choose a bag that is larger than the garment, so that it can lie flat without sharp creases.
  
• Hidden zipper, protected with a small flap, or soft closure that does not tear.
  
• Avoid coarse mesh. It can leave marks or increase friction.

One or more garments per bag, how much is enough?

• One garment per bag ensures minimum friction and even washing.
  
• If you have to combine, stick to the same color and similar weight and knitting.
  
• Leave about 30 to 40 percent air in the bag to allow the water to circulate and the detergent to rinse out.
  

Centrifugation that does not destroy the mold: speed, time and aftercare

Wool is heavy when it is wet. Hard and long spinning can stretch the stitches and distort the shafts and cuffs. By lowering the speed and shortening the time, you reduce the pulling forces. A quick, gentle spin is often enough to remove the dripping water.
Balance the drum, avoid over-spinning, and instead go short and easy. Afterwards, towel pressing and plant drying do the rest.

The right speed 

Use short spin cycles, often 30 to 60 seconds at the end of the program. Avoid over 800 rpm.

Balance the drum and avoid long spinning

• Put in a clean towel to even out the weight, especially if you are washing a single garment.
  
• If the machine shakes, stop and redistribute.
  
• Skip the extra spin cycle. Two short ones are better than one long one if the garment feels dripping wet.

Aftercare that keeps its shape: towel pressing, plant drying and shaping

• Lift the garment with both hands. Avoid pulling on the shoulders.
  
• Squeeze out the water by placing the garment on a dry towel and rolling lightly.
  
• Lay flat on dry towel or drying net to dry wool gently. Dry flat and shape shoulders, sleeves, length and width.
  
• Measure against a favorite garment if you want to hit the right measurements.
  
• Turn occasionally during drying. Avoid direct sun, radiators and tumble dryers.

Saving shape and size: what to do if it's already gone wrong

Has the garment shrunk and matted? It's hard to get it back to full size. You can try soaking in lukewarm water with some hair conditioner or wool conditioner. Massage gently, stretch the garment back to the correct size, and blot dry.

If the garment has stretched, wash briefly on a low temperature wool program. Shape slightly less when flat drying. Repeat two gentle washes rather than trying to force everything at once.

Final tips for longer life

• Air between uses. Wool clears odors naturally.
  
• Wash infrequently. This preserves the quality of the fibers and extends the life of the garment.
  
• Store folded, not hung, to avoid stretched shoulders.
  
• Give your garment rest days. Fibers feel better when they are allowed to recover.

Conclusion

With the right wool program, the right wash bag and a short, low spin, the wool will keep its shape and feel. Use enzyme-free detergent, fill the machine lightly, and finish by drying flat and shaping. Save this guide and start with a less delicate wool garment to build confidence. Wash less often, air more often, and you'll preserve the lanolin oil in the wool and get soft, clean garments that last a long time.
