Not sure if you can wash your pillow? For example, because washing instructions are no longer present or the labels are illegible? Should you want to wash your pillow, but your are unsure if you can? Hand washing is the safest option. In general, the following table applies:

Pillow typeHow to wash
Down or feathersHand wash or washing machine max 30°C, fine detergent or shampoo
SyntheticDirectly in the washing machine, fine detergent
WoolVery good airing or cold hand washing only
Neck support pillowsAlways remove neck support first
Mold cushions (gel, visco or foam)Hand wash and aerate well

Most pillows, both down and synthetic, are machine washable. However, it is important to follow the washing instructions on the label. These instructions may vary by filling and type of pillow.

With an ergonomic neck support pillow, the neck support can (or must) often be removed separately before washing. Molded pillows made of memory foam, latex or gel usually cannot be washed (properly). They suck up the water and become very heavy so you can damage them during the spin cycle. So let these varieties air well and always use a good pillow protector that you wash often.

If your pillow is washable according to the label, it is recommended that you wash it at least once a year. This will flush sweat, dander and the like out of your cover (ticking) and filling.

To protect your pillow from dirt, as well as wear and tear, a good and extra protective pillowcase is very important. The pillowcase should also be washed in a timely manner, at least once a week.

You may need to wash your pillow more often, if you perspire a lot or suffer from allergies. Your pillow will need renewal sooner anyway but this way you avoid unsightly and unsanitary-looking yellow stains. If you want to wash your pillow to remove yellow stains, read first:

Like down, wool is a natural product. Wool is very prone to shrink greatly when you wash it at temperature. Why is that? Well, small, toothed scales cover the surface of wool fibers. When wool is machine washed, these scales can interlock, causing the wool to felt and shrink. To avoid this entanglement, wool is usually dry cleaned, steamed or hand washed with a wool detergent.

Can you wash a pillow with wool

Do you have a pillow stuffed with wool? Then know that it is best to ventilate this fine pillow very well! Wool also holds dirt much less, so feel free to hang it outside on an overcast day with some wind.

Is there any washable wool?

Washing a pillow with wool is possible if, for example, a special treatment has taken place on the wool. For example, the Hercosett treatment. This treatment makes the wool washable. However, you can no longer speak of a 100% natural product.

Even the well-known brand Patagonia has already reported on this, follow the link to a statement from this company. First, the wool fiber is exposed to chlorine and then treated with Hercosett 125, a polyamide-epichlorohydrin polymer.

Does washable wool exist

An additional problem is the waste water that eventually remains at the end of the process. Chlorine reacts with carbon compounds, creating toxic dioxins that remain in wastewater.

This wastewater can be treated, but it is not without risks. Want to know more about this story? Through this link you can retrieve, in English, some more information.
