A short summer shower is enough, and seat pads or lounge cushions can be soaked through to the core. Now it's not about as much heat as possible, but about a controlled process: press the water out, allow air to reach all sides and only store them when seams and filling are dry. This reduces the risk of musty odors, mildew spots and permanently clumped foam.
The first ten minutes are decisive
- Remove cushions from the wet seating surface immediately. Stand them upright under a roof. Otherwise the underside will remain in a film of water on the furniture for a long time.
- Locate the zipper and care label. Only remove the cover if the construction and manufacturer instructions allow it. The care label states the maximum permissible treatment.
- Gently press out the water. Place absorbent towels on both sides and press evenly. Do not wring, twist, or kneel on the cushion.
- Create airflow. Place each cushion separately with space on a drying rack or on a clean, dry edge. Turn it regularly.
A waterproof storage box is practical for dry cushions, but the wrong place for wet ones: moisture can hardly escape from a closed container. A stack on the floor also slows drying because the contact surfaces are poorly ventilated.
Check the material before washing
| Type | Recommended procedure | What to watch for |
|---|---|---|
| Removable, washable cover | Clean the cover separately according to the care label and dry it back into shape. | Close zippers, separate colors, and put the cover back on only when completely dry. |
| Fixed cover on foam | Absorb water with towels, treat stains spotwise, and dry upright. | Do not thoroughly soak if the manufacturer does not permit wet cleaning. |
| Thick foam core | Press several times between dry towels and ventilate from all sides. | The surface may appear dry while the core is still damp. |
| Water-repellent outdoor fabric | Brush off dirt first or remove it with a little water. | No aggressive treatment; cleaning and re-impregnation only as per manufacturer's instructions. |
GINETEX points out that care symbols indicate the maximum permissible treatment. A wash tub with a number indicates the maximum temperature, bars require a gentler mechanical action. If washing is crossed out, even wet cleaning may be unsuitable. Therefore do not remove the label hastily and photograph it for new cushions.
Completely dry garden cushions in five steps
1. Remove coarse dirt
First gently brush off leaves, blossoms and soil. Do not rub wet dirt deeper into the fabric. For bird droppings or sticky residues follow the manufacturer's instructions; any cleaning agent should first be tested on a hidden area.
2. Clean only as much as necessary
If the cover is washable, dose the appropriate detergent according to the instructions and do not overload the machine. DIE UMWELTBERATUNG recommends color or delicate detergent for colored and delicate items and advises against fabric softeners and hygiene boosters. For a non-removable cover, drying after clean rain is often enough; visible dirt should be treated selectively rather than over a large area.
3. Press out moisture
Change the towels as soon as they become wet. For removable foam, press from top to bottom without bending the core. A wet vacuum is only an option if the manufacturer and material allow it and the device is clean.
4. Place in shade and with good airflow
Air drying is the gentlest method for many textiles. An ideal spot is a covered area with air circulation. Direct strong sun or hot heaters are not universal accelerators: colors, coatings and foams can react sensitively. The label and manufacturer instructions remain decisive.
5. Check the core and seams
Don't check only the surface. Press a dry kitchen towel against the thickest spot and the seams. If it remains damp or the core feels noticeably cooler than the surroundings, the cushion needs more air. Only once dry, fluff up, re-cover and store loosely.
What you should rather not do
- Stacking wet cushions: The contact surfaces remain trapped.
- Sealing in foil or a box: That does not create drying but locks in moisture.
- Using a hairdryer or radiant heater: Localized heat can stress materials and adhesives.
- Bleaching without checking: The care symbol decides whether bleach is permitted. Always test stain removers in a concealed area.
- Masking musty odors: Fragrance sprays do not solve the cause of dampness.
Mildew stain or visible mold?
A musty smell is a warning signal but not yet a definite diagnosis. Visible spot-like or patchy growths should be taken seriously. DIE UMWELTBERATUNG explains that moisture promotes mold growth and textiles directly infested with mold must be disposed of. Therefore do not spray mold removers, vinegar or bleach on garden cushions on suspicion. Separate any visibly affected item from the other cushions and check with the manufacturer or a specialist whether the cover and core of high-quality, multi-part pads can be replaced separately.
Prepare for the next shower
- Place a weatherproof box in a dry location and ventilate it regularly.
- Only store completely dry cushions and do not press them up to the lid.
- Document removable covers and spare part numbers when purchasing.
- Stand cushions upright under cover in uncertain weather instead of covering them flat.
- Also keep the frame clean; our guide shows you how to Cleaning plastic garden furniture.
Frequently Asked Questions
How long do garden cushions need to dry?
A fixed number of hours would be unreliable. Thickness, filling, airflow and weather decide. The cushion is only dry when the surface, seams and core show no moisture and do not smell musty.
Can garden cushions go in the washing machine?
Only if the removable cover is suitable for this according to the care label and fits in the drum. The foam core does not automatically belong in there. Do not improvise if the washing symbol is crossed out.
What helps with high humidity?
More space, frequent turning and a well-ventilated, covered spot. How to generally prevent laundry from getting musty in muggy conditions, our supplementary guide explains.
