How to Clean a Baby Crib: The Complete Guide

Your baby sleeps 12 to 16 hours a day. Their face is pressed against the mattress. They breathe in whatever is on and inside that surface — dust mites, bacteria, mould spores, dried milk, sweat, and skin cells. A clean crib is not about aesthetics. It is about creating a safe, hygienic environment for a person whose immune system is still developing.

This guide covers how to clean every type of baby crib — standard cots, bedside cribs like the Chicco Next to Me and SnuzPod, and Moses baskets. We will cover the mattress (which is where the real hygiene risk sits), the frame, the fabric components, mould prevention, and what to do with a second-hand or stored crib before your baby sleeps in it.

Why crib cleaning actually matters

A crib mattress is a breeding ground for things you cannot see. Dust mites feed on dead skin cells — and a baby sheds plenty of them. Bacteria thrive in the warm, slightly damp environment created by a sleeping baby. Mould spores can develop in mattress foam that has absorbed moisture from sweat, milk, or nappy leaks. None of these are visible on the surface, but all of them can affect your baby's breathing, skin, and general health.

A dirty crib mattress has been linked to increased risk of allergic reactions, eczema flare-ups, and respiratory irritation in babies. The Lullaby Trust recommends a clean, firm, flat mattress as a cornerstone of safe sleep. "Clean" does not mean wiping the surface once a month — it means regular, thorough cleaning of the mattress, bedding, and frame.

How often should you clean a baby crib?

A practical cleaning schedule that balances hygiene with the reality of having a newborn:

• Bedding (sheets, mattress protector): Wash weekly at 40–60°C to kill dust mites and bacteria. Wash immediately after any spit-up, milk spill, or nappy leak.
• Mattress surface: Wipe down weekly with a damp cloth. Deep clean monthly (bicarbonate of soda method — detailed below).
• Frame and slats: Wipe weekly with a damp cloth. Deep clean monthly.
• Fabric liners and bumpers (if used): Wash monthly at 30–40°C, or immediately after soiling.
• Full strip-down clean: Before a new baby uses the crib, after storage, or after illness.

The mattress: the most important part

The mattress is where the hygiene risk concentrates. Everything your baby produces — sweat, saliva, milk, urine — eventually reaches the mattress, even through a waterproof protector. Here is how to clean it properly.

Weekly surface clean

• Remove all bedding and the mattress protector
• Wipe the mattress surface with a damp cloth and mild baby-safe detergent
• Pay attention to the edges and corners where debris collects
• Wipe again with a clean damp cloth to remove any detergent residue
• Allow to dry completely before putting bedding back on

Monthly deep clean

• Strip the mattress completely — remove protector, sheets, everything
• Vacuum the entire mattress with an upholstery attachment — top, bottom, sides, and seams
• Sprinkle a generous layer of bicarbonate of soda over the entire surface
• Leave for 30 minutes (longer is fine). The bicarbonate absorbs moisture, neutralises odours, and draws out embedded dirt
• Vacuum off thoroughly
• If the mattress has a removable cover, take it off and machine wash at 40°C
• Flip or rotate the mattress (if the manufacturer recommends this — not all baby mattresses are designed to be flipped)
• Allow to dry completely in a well-ventilated room before reassembling

Stain removal

For milk, urine, or food stains that have soaked through to the mattress:

• Blot immediately with a clean cloth — do not rub, as this pushes the liquid deeper
• Mix a solution of warm water and mild detergent. Dab onto the stain with a cloth
• For stubborn stains, make a paste of bicarbonate of soda and water. Apply, leave for 15 minutes, then wipe off
• For urine stains, a solution of one part white vinegar to two parts water works well. Spray lightly, blot, and air dry
• Never saturate the mattress — excess moisture soaks into the foam and creates the perfect environment for mould

Cleaning the frame and slats

The crib frame — whether wooden, metal, or plastic — needs regular attention. Dust accumulates on horizontal surfaces, and the slats collect grime from tiny hands.

Wooden cribs: Wipe with a damp cloth and mild detergent. Do not use abrasive cleaners or anything bleach-based — they can strip the finish and leave the wood vulnerable to moisture damage. For stubborn marks, a paste of bicarbonate of soda and water applied gently with a soft cloth works well. Dry thoroughly afterwards — water left on wood encourages warping and mould.

Metal cribs: Wipe with a damp cloth. Check for any paint chips or rust spots, especially on older or second-hand cribs. Rust can be gently sanded and repainted with non-toxic, baby-safe paint. Any loose paint should be removed before a baby uses the crib.

Plastic components: Wipe with a damp cloth and mild detergent. Rinse well to remove any residue. For yellowed plastic, a paste of bicarbonate of soda left on for 30 minutes can help brighten it.

Pay particular attention to the joints and screws. Tighten anything loose while you are cleaning — this is your monthly opportunity to do a safety check at the same time.

Bedside cribs (Chicco Next to Me, SnuzPod, Shnuggle)

Bedside cribs have additional cleaning considerations compared to standard cots. The mesh sides, the drop-down panel, and the smaller mattress all need attention.

Mesh sides: These trap dust and can harbour bacteria if not cleaned regularly. Wipe with a damp cloth weekly. For a deeper clean, some models have removable mesh panels that can be hand washed. Check your model's care label.

Drop-down panel: The mechanism where the side drops for night feeds collects crumbs, milk residue, and dust in the hinge area. Wipe the hinge mechanism with a damp cloth and check it moves smoothly.

Fabric covers: Most bedside cribs have removable fabric covers that are machine washable at 30°C. Remove and wash monthly, or after any spill.

The mattress: Bedside crib mattresses are smaller than cot mattresses but need the same care — weekly wipe, monthly bicarbonate deep clean, and always replace the mattress between babies. The Lullaby Trust recommends a new mattress for each child.

Moses baskets

Moses baskets present a unique cleaning challenge because they are made from porous natural materials — wicker, palm, or maize — that absorb moisture and organic matter. You cannot machine wash a Moses basket. You cannot soak it. And the woven structure traps debris that a surface wipe cannot reach.

The fabric liner and mattress cover can usually be removed and machine washed at 30°C. The basket itself should be wiped with a damp cloth and mild detergent, then dried thoroughly in a ventilated room. For mould on a Moses basket, use a solution of one part white vinegar to four parts water — apply with a cloth, scrub gently, and wipe clean.

We have a full guide on Moses basket safety and hygiene that covers this in detail, including when to replace rather than clean.

Dealing with mould on a crib

Mould on a baby crib is more common than most parents realise — especially on cribs that have been in storage, second-hand cribs, and any crib in a room with poor ventilation or damp issues.

On the mattress: If you can see mould on the surface of a crib mattress, replace it. Mould that is visible on the surface has almost certainly penetrated into the foam. You cannot clean mould out of mattress foam effectively — the spores embed in the material and will return. A new crib mattress costs £20–40. It is not worth the risk.

On the frame: Surface mould on a wooden frame can be removed with a solution of one part white vinegar to two parts water. Apply with a cloth, scrub gently along the grain, and wipe clean with plain water. Allow to dry completely. If the mould has penetrated the wood (dark stains that do not come off with vinegar), the frame may need sanding and resealing — or replacing.

On fabric components: Machine wash at 60°C if the care label allows. If not, wash at 30°C with a mild detergent and add a cup of white vinegar to the rinse cycle. Dry completely — fabric that is put back while even slightly damp will grow mould again within days.

Prevention: Keep the crib in a well-ventilated room. Do not push it against a cold external wall (condensation forms between the wall and the crib). Use a waterproof mattress protector. Address any damp issues in the room before the baby sleeps there. If storing a crib, store in a dry location with a breathable cover — never sealed in plastic.

Second-hand and stored cribs

If you are using a crib that has been in storage between babies, bought second-hand, or passed down from family — it needs more than a quick wipe before your baby sleeps in it.

Always buy a new mattress. The Lullaby Trust recommends a new mattress for each baby. Second-hand mattresses may have lost their firmness, and they harbour bacteria, mould spores, and allergens that are invisible. A new crib mattress costs £20–40 depending on size.

Check the structure. Tighten all screws and bolts. Check the slats — none should be loose, cracked, or missing. Test the base for stability. For drop-side cribs (now banned for new sales in the UK), check the mechanism carefully.

Deep clean everything. Wash all fabric components at the highest temperature the care label allows. Wipe the entire frame, slats, and base with warm water and mild detergent. Pay particular attention to areas that were hidden — the underside of the base, the inside of joints, and any areas that look discoloured or smell musty.

Check for recalls. Before using any second-hand crib, search the manufacturer's website for recalls or safety notices for your specific model.

What not to do

• Do not use bleach on any part of a baby crib. Bleach residue is harmful to a baby's skin and airways, and it damages many materials.
• Do not use antibacterial sprays marketed for household cleaning. Most contain chemicals not tested for prolonged infant exposure. Use baby-safe products only.
• Do not soak the mattress. Excess moisture soaks into the foam and creates the perfect conditions for mould. Use as little water as possible during cleaning.
• Do not dry near a radiator or in direct sunlight. Radiator heat can warp wooden frames and shrink fabrics. Direct sunlight fades fabrics and can degrade some mattress materials.
• Do not put the mattress back before it is completely dry. "Mostly dry" is not dry enough. If there is any dampness in the foam, mould will develop.
• Do not reassemble bedding on a damp mattress protector. Even if the mattress itself is dry, a damp protector creates a moisture layer that defeats the purpose of cleaning.

When to use a professional crib cleaning service

For routine weekly and monthly cleaning, the steps above are all you need. But there are situations where a professional clean makes a genuine difference:

• Before a second baby. Months of daily use means accumulated organic matter in the fabric, padding, and frame crevices that surface cleaning cannot reach.
• After storage. A crib that has been in a loft, garage, or spare room for months or years needs thorough inspection and cleaning — especially for hidden mould.
• Second-hand purchase. You do not know how the previous family maintained it, what was spilled in it, or how it was stored.
• Visible mould. If mould has spread beyond a small surface spot, professional treatment is more effective and safer than DIY cleaning.
• Bedside cribs and Moses baskets. The fabric, mesh, and woven components on these are harder to deep clean at home than a standard wooden cot. The padding traps organic matter that a sponge and cloth cannot reach.

Frequently asked questions

How do you clean a baby crib?

Strip all bedding. Wash the mattress cover at 40°C. Vacuum the mattress, then sprinkle bicarbonate of soda over the surface, leave for 30 minutes, and vacuum off. Wipe the frame and slats with warm water and mild detergent. Dry everything completely before reassembling.

How often should you clean a baby crib?

Wash bedding weekly. Wipe the frame and mattress surface weekly. Deep clean the mattress with bicarbonate of soda monthly. Do a full strip-down clean before a new baby uses it, after storage, or after illness.

Can you clean mould off a crib?

Surface mould on the frame can be removed with a white vinegar solution. If mould has penetrated the mattress foam or deep into the wood grain, replacement is safer than cleaning. Mould spores can irritate a baby's airways and trigger allergic reactions.

Should you clean a second-hand crib before using it?

Yes — always. Buy a new mattress (the Lullaby Trust recommends this for every baby), check the structure for damage, tighten all screws, and deep clean every component. Check the manufacturer's website for any recalls on your model.

What should you not use to clean a baby crib?

No bleach, no ammonia-based cleaners, no antibacterial household sprays, and no abrasive cleaners. Use only baby-safe products — warm water with a mild detergent covers most cleaning needs. Bicarbonate of soda and white vinegar handle tougher jobs safely.

How much does professional crib cleaning cost?

Our crib and sleep item cleaning starts from £45. This includes a full strip-down, baby-safe deep clean of all components, and free collection and delivery across London. We clean Next to Me cribs, Moses baskets, SnuzPods, and all baby sleep items.
