TL;DR
A playard cleans best fully open and standing: vacuum the crumbs out, wash the mesh and rails with mild soapy water, handle the pad according to its own label, then dry the whole thing open in moving air for several hours. Folding it damp is what produces the musty smell people complain about.
Set it up before you clean it
Open the playard fully and lock every rail. Cleaning it half-folded means you miss the inside of every crease, which is exactly where the mess lives.
Take out the pad, the bassinet insert, the changing attachment, and any toy bar. Each of those has its own care instructions.
Check the manual for anything the manufacturer prohibits. Some brands are specific about what may touch their mesh or their fabric rails.
Work outside or over a hard floor. The first vacuum pass releases a surprising amount.
Vacuum before you add any water
Crumbs plus water equals paste, and paste in a mesh weave is much harder to remove than dry crumbs.
Use a crevice tool along every corner seam, the floor perimeter, and the channel where the fabric floor meets the mesh walls. Then vacuum the mesh itself with a soft brush attachment.
Shake the whole unit gently and vacuum again. Things migrate.
How do you clean pack and play mesh?
Wipe pack and play mesh with a soft cloth dampened in warm water and mild soap, doing both the inside and outside faces, then go over it again with a cloth wrung out in plain water. Air dry with the playard open. Never scrub hard or use a stiff brush, because torn mesh is a safety issue rather than a cosmetic one.
Work along the weave rather than in circles. Mesh stretches, and circular scrubbing distorts it.
For a set-in spot, hold a warm damp cloth against it for a minute to soften the residue, then wipe. Patience beats pressure here.
Inspect the mesh while you go. Holes, thin spots, and separation from the binding are all reasons to stop using the playard and contact the manufacturer.
Rails, corners, and the frame
Fabric-wrapped rails take the same warm soapy cloth. Get the underside of each rail, which collects dust nobody sees.
Corner hubs and hinges hold hair and crumbs. A dry brush first, then a damp wipe, then dry them properly, because water sitting in a hinge is how a lock gets stiff.
Wipe the legs and feet last, since they carry floor grime. Do them at the end so you are not spreading it upward.
Do not spray liquid directly into any joint or into an electronic module if your model has a vibration or sound unit. Spray the cloth instead.
The pad follows its own rules
Most playard pads have a firm board or foam core inside a wipeable cover, and that means wipe-only. Water that reaches the core takes days to leave and grows mildew.
Wipe the pad with mild soapy water, rinse-wipe with plain water, blot dry, and stand it on edge so both faces get airflow.
If your model has a removable, machine-washable pad cover or a separate sheet, wash that per its tag. Waterproof-backed covers wash warm and dry low or air only, since heat cracks the backing.
The same logic applies to the crib, and how to clean a crib mattress cover goes deeper on why the backing fails.
Never add a mattress, pillow, or extra padding that did not come with the playard. Use only the pad the manufacturer supplied, plus a snugly fitted sheet made for it.

Why does a pack and play smell musty?
A musty smell almost always means the playard was folded and stored while some part of it was still damp, so mildew developed inside the fabric or the pad core. Clean the surfaces with mild soap, rinse, and then dry the unit fully open in moving air for several hours before folding it.
If the smell survives a full clean and dry, check the pad core and the underside of the fabric floor, which are the two places moisture hides.
Mold and mildew growth inside a foam core is not something surface cleaning fixes. If a pad is contaminated, replacing it through the manufacturer is the honest answer, and a large mold problem in a home is a remediation trade, not a cleaning task.
Drying and storing so it stays fresh
Leave the playard open until every surface is dry to the touch, including the underside of the floor and the inner face of each mesh panel. In a damp climate that can take most of a day, and a fan helps a lot.
Do not use a heater or hair dryer. Heat can distort plastic hubs and stress the mesh binding.
Store it in its bag only once fully dry, and store the bag somewhere dry rather than a damp garage corner. If it has been in storage for a season, open it and air it out before use.
A realistic schedule
Vacuum weekly if it is in daily use. Wipe the mesh and rails monthly. Do the full clean before and after any trip, and any time it comes out of storage.

FAQ
Can you machine wash a pack and play?
No. The frame, mesh, and fabric are one assembly and cannot be separated for a machine cycle, and agitation would damage the mesh and the binding. Clean it in place with warm soapy water and a cloth, rinse-wipe with plain water, and air dry it fully open.
How do you clean mold off pack and play mesh?
Wipe the affected mesh with mild soapy water, rinse with a plain damp cloth, and dry the playard completely in moving air, since ongoing dampness is the actual cause. If the growth is extensive, has penetrated the pad core, or returns after a thorough clean and dry, replace the affected parts rather than continuing to treat the surface.
Can you wash a playard mattress pad?
Usually not by submerging it. Most pads have a board or foam core that traps water for days and grows mildew, so they are wiped with mild soapy water and dried on edge instead. If your model has a removable machine-washable cover, wash that and keep the core dry.
What cleaner is safe for a pack and play?
Mild dish soap in warm water covers nearly everything, followed by a plain-water wipe. Avoid bleach, ammonia cleaners, and strong solvents, and never mix bleach with ammonia or with an acid. Keep fragrance out of a sleep space, since a baby spends hours with their face close to that surface.
How long should a playard dry before folding it?
Until every surface is dry to the touch, including the underside of the floor and the inner face of the mesh, which usually means several hours and sometimes a full day in damp weather. Folding it even slightly damp is the most common cause of the musty smell people find at the next use.
How often should you clean a playpen?
Vacuum weekly with daily use, wipe the mesh and rails about monthly, and do a full clean before and after travel or storage. Clean immediately after any spill, blowout, or illness, and dry it fully open each time rather than folding it up right away.
