Squishy collections grow fast: between store-bought and homemade, suddenly there are twenty pieces scattered around the house, some grimy, one smelling odd at the bottom of a backpack. This guide solves both ends of the problem — how to clean without destroying, and how to store so they last for years.
Rule number one: squishies hate water
Open-cell foam works like a sponge: it absorbs water easily and gives it back with enormous reluctance. Water trapped in the core is a straight path to mold, and internal mold cannot be fixed. Therefore:
- Never submerge them, rinse them under the tap or put them in the washing machine.
- All cleaning is external and surface-level.
- If an accident soaks a piece, go straight to the emergency section at the end of this article.
Routine cleaning (every few weeks)
To remove dust and that light grime from handling:
- A dry microfiber cloth, or one slightly dampened (wrung out as much as possible), wiped in gentle strokes.
- A soft makeup or paint brush for dust in crevices — cloud folds, donut holes.
- On painted homemade pieces, press lightly; hard rubbing polishes the paint away. If your piece followed our painting guide with sealing, it handles that damp cloth just fine.
Localized stains
For pen, chocolate or a child's post-snack fingers:
- Mix one drop of mild dish soap into half a cup of water.
- Dampen the tip of a cloth or cotton swab in the mixture — the goal is to moisten the stain, not the piece.
- Dab the stain, working from the edge toward the center, without rubbing.
- "Rinse" by repeating the dabbing with a water-only cloth, also nearly dry.
- Dry with a dry cloth, pressing gently, and let the piece air out for a few hours.
Honest expectation: an old stain on light foam rarely comes out completely. On homemade pieces the definitive solution is different — a fresh coat of paint on top, which renews the whole piece.
Permanent marker ink and stuck-on slime are lost causes for cleaning; on homemade pieces, treat it as wear and repaint; on store-bought ones, accept the scar with affection.
Musty smell
A squishy left shut in a backpack or box picks up a smell. Before any product:
- Let the piece air out in the shade for 24 to 48 hours in a ventilated spot. That solves most cases.
- If it persists, put the piece in a closed box with a handful of baking soda in an open little container beside it (not touching the piece) for two days.
- Never spray perfume or disinfectant: besides staining, the liquid soaks into the foam — and we're back to the water problem.
A moldy smell with dark spots is another story: for safety, especially with children at home (see our safety guide), the piece should be discarded.
Organizing the collection
What preserves the pieces
- Shade, always: sunlight fades paint and dries out polyurethane — it's one of the mistakes that kill the most squishies.
- No squashing: a piece stored crushed for weeks deforms forever and loses its spring, including the slow-rising effect. No cramming boxes with weight on top.
- Ventilation: open or perforated containers; foam likes to breathe. Airtight tubs only for short trips.
- Away from heat: no storing near a hot window, a lamp, or in a car in the sun.
Display ideas that work
- Cubbies or a shallow shelf, with the pieces in a single row — each one visible, none squashed.
- A shallow open basket for the "daily use" pieces, near where you actually use them.
- An organizer box with dividers (lidless, or with a perforated lid) for large collections: one piece per slot, nothing stacked.
- For light pieces, a mini-clothespin garland on the wall — clip by a reinforced edge, never by thin parts.
Rotation
Big collection? Display half and keep the other half stored with airflow; swap every month. The pieces "rest" from light and dust, and the shelf gets a fresh look every so often.
Emergency: it got properly soaked
- Press the piece between two dry towels, swapping the towel when it saturates. Do not wring — wringing tears foam and cracks paint.
- Leave it in a ventilated, shaded spot for 2 to 4 days, turning the piece daily.
- Before storing, do the weight test: a piece heavier than normal still has water inside.
- If dark spots or a moldy smell appear days later, discard it. If the piece survived but the paint suffered, the repair guide covers the touch-up.
