Washing and caring for your virgin wool blanket
Pure new wool largely cleans itself. If you understand this natural principle, you'll wash less often and make significantly fewer mistakes. As a manufacturer, we'll show you what really matters when it comes to care.
Washing and Caring for a Pure New Wool Blanket - How to Keep it Soft and Warm
Ideally, you should wash a pure new wool blanket as rarely as possible, and this is not a compromise, but the secret to its long lifespan. Pure new wool naturally has almost everything it needs to keep itself clean. At Ritter Decken, we have been manufacturing natural hair blankets in Germany for eight generations since 1766, and we know the characteristics of this fiber in detail. In this guide, you will learn when washing is even necessary, how to remove individual stains without a complete wash, and how to successfully wash without felting.
Why Pure New Wool Almost Cleans Itself
What Lanolin Wool Grease Does in the Fiber
Pure new wool retains a natural residual fat content, known as wool grease or lanolin. It is water-repellent, neutralizes odors, and makes it difficult for dirt particles to even settle. This fat is the most important care aid for your blanket, and every wash rinses out some of it.
In addition, there is the dense fiber structure. The hairs are so interwoven that dust and crumbs can hardly penetrate, but remain on the surface and can be easily shaken out. The wool absorbs moisture and releases it back into the air, which makes it pleasantly temperature-regulating.
In practice, this means a well-maintained pure new wool blanket stays fresh for years without ever being in the machine.
Air Instead of Wash and Proper Storage
Instead of washing, air your blanket regularly outdoors. A shaded, protected spot with slightly higher humidity is ideal, as the pile regenerates there and the fibers straighten up again. In most cases, airing replaces a complete wash.
Out of season, loosely fold the blanket and store it in an airtight polybag. This protects it from moth infestation without you having to place mothballs directly on it, which can leave unpleasant odors.
What Distinguishes Pure New Wool from Other Wools
Pure New Wool, Merino, and the Label "Pure New Wool"
Pure new wool is shorn from living sheep and is therefore different from recycled fiber remnants. The label "pure new wool" stands for new, first-processed wool of high quality. For our pure new wool blankets, we exclusively use such exquisite pure new wools.
Merino holds a special position. The fine wool from Merino sheep is particularly soft and fine to the touch. A Merino wool blanket feels more delicate than coarser qualities, but is somewhat more sensitive to heat and movement.
Robust but Not Indifferent
Among natural hairs, pure new wool is considered the most durable fiber. It can withstand more stress than fine cashmere or soft alpaca and is therefore also suitable for daily use on sofas and beds.
However, robust does not mean indestructible. Pure new wool also has the typical scale structure and can felt if treated incorrectly. The following rules therefore apply to every genuine wool blanket, no matter how strong the fiber seems.
Why Heat and Friction Cause Pure New Wool to Felt
The Scale Structure of the Wool Fiber
Each wool fiber is surrounded by tiny scales, similar to shingles on a roof. When heat, moisture, and mechanical movement come together, these scales stand up and intertwine. This process is called felting and cannot be reversed.
Precisely this effect is deliberately used in fulling, for example to produce sturdy fulled fabric. For a cozy blanket, the opposite is desired, namely a loose, soft pile.
The Right Temperature for Washing Pure New Wool Blankets
Therefore, when washing a pure new wool blanket, the most important rule comes first. Stay with cold to at most lukewarm water below 30 degrees. Above approximately 30 to 40 degrees, the protective lanolin separates from the fiber, and the risk of shrinking and felting increases significantly.
| Temperature | Effect on the Pure New Wool Blanket |
|---|---|
| Cold below 30 degrees | Optimal, lowest felting risk |
| 30 degrees | Only acceptable with wool program |
| 40 degrees | Lanolin is washed out, blanket may shrink |
| 60 degrees | Unsuitable, strong felting and shrinking |
The table clearly shows that every degree counts. Washing cool protects the natural wool grease and maintains the soft feel of your blanket for many years.
Removing Stains from a Pure New Wool Blanket Without a Full Wash
Treat Fresh Stains Immediately and Spot Clean
The gentlest cleaning is when only the affected area is treated. If you have a stain, react as quickly as possible while it is still fresh. Gently dab it with cold water from the outside in, so that it does not spread further.
Do not rub, because friction is exactly the trigger that wool does not tolerate. Often, clear water is enough to clean a small area of a pure new wool blanket.
Gentle Home Remedies That Don't Harm the Wool
If water alone is not enough, apply a drop of mild wool detergent to the spot and gently work it in. Always test any product on an inconspicuous area first, such as the back of the hem.
Absolutely avoid bleach, enzyme-based stain removers, or pre-wash sprays. These attack the fiber. The great advantage of spot cleaning is that the rest of the blanket retains its valuable lanolin.
Washing and Drying a Pure New Wool Blanket Step by Step
By Hand in the Bathtub
If the entire blanket needs cleaning, hand washing is the safest method. This is the gentlest way to wash a pure new wool blanket, and even a coarser pure new wool blanket can be washed this way without any risk. Fill the tub with lukewarm water below 30 degrees and dissolve a mild wool detergent completely before putting the blanket in the water.
Submerge it and gently press the water through the fabric, without rubbing, wringing, or kneading. Then rinse with water of the same temperature, as a sudden change in temperature can damage the fibers just as much as water that is too warm.
In the Washing Machine on a Wool Program
Can a pure new wool blanket be washed in a washing machine without damaging it? Yes, if you observe a few points. If you want to wash a pure new wool blanket in the washing machine, you must select the wool or hand wash program and place the blanket individually in the drum. Reduce the spin speed to a maximum of 400 revolutions and stop the process after just three minutes. A certain residual moisture is even desirable.
A gentle wool detergent is suitable as a detergent, or alternatively a commercially available conditioner (i.e., hair conditioner) directly in the main wash cycle. Heavy-duty detergents and fabric softeners have no place in wool washing, as they attack the fiber or leave unnecessary residues.
Gentle Air Drying
Never put a pure new wool blanket in the tumble dryer, as heat and drum movement will inevitably felt it. Instead, spread the wet blanket on an absorbent cotton towel and loosely roll both together so that the towel absorbs the coarsest moisture.
A wet wool blanket is surprisingly heavy, so distribute its weight over several clotheslines or dry it flat. Choose an airy, shady spot away from heaters and direct sun. Finally, shake the dry blanket vigorously so that the pile regains its volume.
Having a Pure New Wool Blanket Professionally Cleaned: When a Professional Cleaning is Worthwhile
Large Blankets, Special Sizes, and Stubborn Stains
Not every blanket can be conveniently washed at home. For very large formats, heavy duvets, or particularly valuable pieces, home washing quickly reaches its limits. Deeply ingrained or oily stains also suggest having a pure new wool blanket professionally cleaned rather than experimenting yourself.
Before you go this route, however, always check whether thorough airing or spot treatment is sufficient.
What to Look for When Choosing a Cleaner
If you decide on professional cleaning, specifically ask about their experience with wool and for the gentlest possible process. Explicitly point out the delicate material so that the blanket is treated correctly.
Keep in mind that every chemical cleaning removes residual fat from the wool, which can make it feel strawier afterwards. From our experience as manufacturers, we therefore advise using professional cleaning only in exceptional cases and only for truly stubborn cases.
Conclusion
The best way to wash a pure new wool blanket is rarely, cool, and with as little movement as possible. Air it regularly, treat stains on the spot, and avoid heat and the dryer to preserve the protective lanolin and keep your blanket soft for many years. Anyone who observes these few rules will enjoy pure new wool for a long time. In our range of natural hair blankets, you will find specialist retail quality, manufactured in Germany and tested for harmful substances. If you have any questions about care or selection, please feel free to contact us; we will advise you personally.
Frequently Asked Questions About Washing Pure New Wool Blankets
How often should you wash a pure new wool blanket?
As rarely as possible. In most cases, regular airing outdoors is sufficient to keep the blanket fresh. A complete wash is often only really necessary after several years or with heavier soiling.
Can you wash a pure new wool blanket in the washing machine?
Yes, but only on the wool or hand wash program with cold water, individually, and with a maximum of 400 revolutions during spinning. Hand washing remains the gentlest option, especially for fine or high-quality blankets.
Does a pure new wool blanket shrink when washed?
With cold water and little movement, it generally does not shrink. Shrinking and felting occur due to the combination of heat and mechanical friction, which is why low temperatures and a gentle program are so important.
What to do if the pure new wool blanket feels hard after washing?
This is usually due to lost wool grease or too much heat. Shake the dry blanket thoroughly and rinse with some conditioner next time. With use, pure new wool often becomes softer again over time.
