A knocked-over glass of water, a rain shower through an open window, a dog with wet paws, or just a heavy summer night: there are a hundred ways a pillow can get wet, and they all feel like a small household emergency. Yet, a wet pillow is rarely lost, as long as you do the right things in the first few hours, and most importantly: avoid doing a few tempting things. Here's the step-by-step plan.
The short answer
If your pillow gets wet, first determine which layer is wet: often only the pillowcase and cover are wet, and the core remains dry. Remove the wet layers immediately and wash them according to the label. If the core itself is wet: blot it dry with towels (do not wring), let it dry flat in an airy, dry place, and keep it away from heaters, hairdryers, and tumble dryers. Expect one to two days of patience; only if odor or stains persist is the pillow truly lost.
Step 1: Which layer is actually wet?
A pillow is a layered system: pillowcase, often a cover underneath, and only then the core. In the average accident, the damage is limited to the outer layers; they absorb the impact like a coat absorbs rain. So, first take everything apart and feel each layer. Wet pillowcase but dry cover? Then you're done with one wash. Damp cover but a core that only feels clammy on the surface? Then it's not too bad.
This first minute determines the entire operation. The biggest mistake is to leave the pillow as a whole so that the moisture can slowly seep in; speed is your best friend here.
Step 2: How do you dry a wet pillow core?
If the core itself is wet, tackle it like this: place the pillow on a thick, dry towel and press a second towel on top with flat hands, so that the towels absorb the moisture. Repeat this with dry towels until little more comes out. Then lay the core flat in a dry, airy place, for example, on a drying rack so that air can circulate underneath, and turn it over occasionally. Allow one to two days; drying a pillow is a matter of patience, not force.
What you should never do with a foam core: wring it (that damages the structure), put it in the tumble dryer, or place it on the heater or in direct sunlight. Foam and heat are not friends, and a crumpled or crumbled core cannot be restored. More about daily care can be found in cleaning and maintaining a memory foam pillow.
When is a wet pillow beyond saving?
Most wet pillows survive just fine, but there's a limit. If the pillow has become soaked with something other than clean water (think of a fully leaked cup of coffee or a pet accident deep into the core), or if an odor or stain remains in the core after complete drying, then replacing it is the wise choice. A core that remains wet for days is also a risk: prolonged moisture in a dark bedroom is asking for musty problems.
Are you unsure if the pillow still provides good support after the incident? Then assess it as you would any old pillow; the checklist for this can be found in how long a memory foam pillow lasts.
Smart for next time: work in washable layers
The best protection against a wet pillow is arranged beforehand: ensure there are at least two washable layers between the outside world and the core. A pillowcase catches daily moisture, and a removable cover underneath catches the real accident. Both go straight into the washing machine, and the core remains untouched.
SidePillow works exactly like this: the luxurious, breathable cover unzips and washes at 30 degrees, and the pillow fits into any standard 60x70 cm pillowcase. So if something goes wrong with a glass of water, there's a good chance you'll be done with one zip and a wash, while the shape-retaining core stays dry, waiting for the bed to be made again.
Conclusion
What do you do if your pillow gets wet? Quickly separate the layers, put the wet pillowcase and cover in the wash, and blot a wet core and let it dry flat in an airy place, far from heaters and tumble dryers. With one to two days of patience, almost every pillow survives an accident with clean water; only with persistent odors or stains in the core is it the end of the line.
And the lesson for afterward is surprisingly simple: a pillow with washable layers turns the next knocked-over glass into a chore instead of a small emergency.

Frequently Asked Questions
What should you do if your pillow gets wet?
Immediately separate the layers: remove the pillowcase and cover and put them in the wash. If the core is wet, blot it dry with towels and let it dry flat in a dry, airy place. Do not wring and do not put it in the dryer or on the heater.
Can a memory foam pillow go in the tumble dryer?
No. Foam tolerates the combination of heat and tumbling poorly: the structure can be damaged, and the core can lose its shape. Always air-dry a foam core, flat and with the time it takes.
How long does it take for a wet pillow to dry?
For a wet core, allow one to two days, depending on how wet it is and how airy the drying spot is. Turn the pillow over periodically and ensure air can circulate around all sides.
When should you throw away a wet pillow?
If the pillow has become soaked with something other than clean water, or if an odor or stain remains in the core after complete drying. A core that remains damp for days should also be replaced.
