Child's mattress: how to clean wee, milk and vomit without harsh chemicals
On a child's mattress, accidents are normal: wee at night, milk, vomit. What matters is acting fast and with gentle products, because that is where the child spends ten or more hours a day with their face against the fabric.
Right after the accident
- Strip the bedding and blot the liquid with towels, pressing, not rubbing
- A damp cloth with warm water and a few drops of neutral detergent, only on the stain
- Blot again with a dry towel
- Let it dry with the window open before making the bed again
What never to use
- Bleach and strong disinfectants: they leave smells and residue where the child breathes
- Soaking the mattress: water gets into the foam and takes days to dry, with a risk of mould
- Perfumes and air fresheners to mask the smell
For urine odour specifically, the steps are in urine smell on a sofa or mattress.
Prevention
- A waterproof, breathable protector under the sheet
- Two protectors, to swap at night without waiting for the washing machine
- Turn and air the mattress when you change the bedding
When to deep-clean
When a stain has dried several times in the same spot, when the smell keeps coming back, or before passing the mattress on to a younger sibling. Old yellow stains get much lighter but can leave an outline, as we show in the real mattress case. On frequency and dust mites, see how often to clean a mattress.
What professional cleaning looks like
Injection-extraction equipment that pulls dirt from inside without soaking, with eco-friendly, hypoallergenic products, safe for children and pets, and anti-mite treatment included. Drying takes 2 to 6 hours: book in the morning and by night the child is sleeping on it. Price: €30 per mattress (see how much mattress cleaning costs), under mattress cleaning. In Porto, Vila Nova de Gaia, Matosinhos, Maia and Gondomar.
