TL;DR
A bassinet cleans up with mild soap, warm water, and patience: strip everything, wash the sheet and any washable liner, wipe the frame and mesh, and let all of it dry completely before reassembly. The mattress pad is the part most likely to be surface-wipe-only, so its label decides.
Strip it down and read every label
Take off the fitted sheet, the liner if there is one, and any hanging toys or canopy. Set them out and read each care tag separately, because they are frequently different materials.
The pad is the piece that surprises people. Many bassinet pads have a firm foam or fiber core with a wipeable cover that is not removable, which means it is wiped, never soaked.
Photograph the assembly before you take the frame apart. Bassinet frames often have a specific fold order, and getting it wrong on reassembly is frustrating.
Check the manual for anything the manufacturer specifically prohibits. Some brands rule out particular cleaners on their mesh or fabric.
How do you clean bassinet mesh sides?
Wipe bassinet mesh with a cloth dampened in warm water and a small amount of mild soap, working gently on both sides, then wipe again with plain water to remove soap film. Let the mesh air dry fully with the bassinet open. Never scrub hard, because mesh tears easily and torn mesh is a safety issue.
Mesh matters more than it looks. It is there for airflow, and a hole or a stretched section changes how the sides behave.
Use a soft cloth or a very soft brush, never an abrasive pad. Work along the weave rather than in circles.
If mesh is torn, stretched, or separating from its seam, stop cleaning and contact the manufacturer about a replacement. That is not something to patch.
Washing the sheet, liner, and any fabric cover
Wash the fitted sheet on the setting its tag names, typically warm with a mild detergent. Cool water first is better for milk and spit-up, since heat sets protein stains.
Skip fabric softener on anything a newborn sleeps against. It leaves a residue and can irritate sensitive skin.
Liners and canopies are often gentle-cycle or hand wash. Fasten any snaps and use a mesh bag to keep straps from tangling.
Air dry rather than using high heat. Shrinkage on a fitted sheet is a real problem, because a sheet that no longer fits snugly is a hazard rather than an inconvenience.
The mattress pad is the careful part
Most bassinet pads should not be submerged. Water gets into the foam or fiber core, takes days to leave, and mildew follows.
Wipe the cover with a cloth dampened in mild soapy water, then rinse-wipe with a clean damp cloth. Blot with a dry towel and let it air dry standing on edge so both faces get airflow.
If the pad has a removable, machine-washable cover, wash that per its tag and leave the core dry. Waterproof-backed covers hate high heat, so wash warm and dry low or air only.
The same rule governs the crib, and how to clean a crib mattress cover covers how the waterproof backing behaves.
What about the frame, legs, and wheels?
Wipe metal and plastic frame parts with mild soapy water and dry them right away. Standing water in a joint invites rust and it loosens nothing good.
Get into the joints and the underside of the base, where dust and lint collect out of sight. A dry brush first, then the damp wipe.
Wheels and rockers pick up hair and floor grime. Pull the hair out by hand, wash the rest, and dry the axles.
Do not spray cleaner directly at the frame if the bassinet has any electronic module, sound unit, or motorized rocking mechanism. Spray the cloth instead, and keep liquid away from the module entirely.
What should you never use on a bassinet?
Skip bleach, ammonia-based cleaners, and strong solvents on a bassinet, and never mix bleach with an ammonia glass cleaner or with any acid, because those combinations produce toxic gas. Mild soap and warm water handle almost everything, and anything stronger risks leaving residue where a newborn breathes and mouths.
Fragrance-heavy cleaners are also worth avoiding here. A newborn spends many hours with their face inches from that surface.
If you feel a disinfectant is warranted after an illness, clean the visible soil off first, use a product whose label lists the surface, honor the wet dwell time on the label, and then wipe with plain water afterward.
Cleaning reduces germs and soil. It does not treat or prevent illness, and health questions belong with your pediatrician.
Drying and reassembly
Leave every part open and separated until dry to the touch, including the underside of the pad and the inside of the mesh. In a damp climate this can take longer than you expect.
Do not use a hair dryer or a space heater to speed it up. Heat distorts plastic and can damage foam.
Reassemble using your photos, then check that every lock, latch, and leg is fully engaged. Push down gently on the sides to confirm the frame is stable.
Finish with a snugly fitted sheet and nothing else in the sleep space. Loose bedding, pillows, and bumpers are not part of a safe sleep setup.

Keeping it easy between deep cleans
Keep two fitted sheets and swap rather than scrubbing. A quick wipe of the pad after every spill takes seconds and prevents a set-in stain.
Once a month, do the fuller version: mesh, frame, joints, wheels. The general approach in our guide to cleaning baby gear and kids equipment safely applies to the rest of the nursery, and how to clean a playpen or pack and play uses nearly the same routine on a bigger frame.
FAQ
Can you wash a bassinet mattress pad?
Usually not by submerging it. Most bassinet pads have a foam or fiber core that traps water and grows mildew, so they are surface-wiped with mild soapy water and dried thoroughly instead. If the pad has a removable cover marked machine washable, wash the cover and keep the core dry.
How do you get a stain out of bassinet mesh?
Blot with cool water first, then work a drop of mild soap in with a soft cloth, moving gently along the weave. Rinse with a clean damp cloth and air dry. Avoid scrubbing, abrasive pads, and bleach, since mesh tears easily and a torn panel is a safety problem, not a cosmetic one.
What cleaner is safe to use in a bassinet?
Mild dish soap in warm water covers almost everything a bassinet needs. Avoid bleach, ammonia, strong solvents, and heavily fragranced products, and never combine bleach with ammonia or with an acid. Whatever you use, wipe afterward with plain water so no residue is left where a newborn breathes.
How often should a bassinet be cleaned?
Change the fitted sheet every few days or immediately after a spill, wipe the pad whenever something lands on it, and do a fuller clean of the mesh, frame, and joints about once a month. Newborn gear gets messy in small amounts constantly, so short frequent cleaning beats rare deep cleaning.
Can you use disinfecting wipes on a bassinet?
Only on hard plastic surfaces the label lists, and only after removing visible soil, since disinfectants do not work on dirty surfaces. Honor the wet dwell time on the label, then wipe with plain water. Do not use them on the mattress pad surface or on mesh.
How long does a bassinet need to dry?
Until every part is dry to the touch, including inside the mesh and under the pad, which often means several hours to overnight in moving air. Do not speed it up with a hair dryer or heater, because heat can warp plastic parts and damage foam. Reassembling damp is how mildew starts.
