TL;DR
Which cleaner is safe depends entirely on whether your mat is open cell or closed cell, and using the wrong one degrades the surface permanently. Wipe the mat with a mild soap-and-water solution after every practice, skip alcohol, essential oils, and harsh disinfectants, and always let it dry flat and completely before rolling it up.
The one thing to figure out first
Yoga mats come in two constructions, and they behave completely differently.
Closed cell mats have a sealed surface. Sweat sits on top rather than soaking in, which makes them easy to wipe clean but slippery when wet. Most inexpensive PVC and TPE mats are closed cell.
Open cell mats have a porous surface that absorbs moisture, which is what gives them their grip when your hands are sweaty. That absorbency also means they soak up everything else, including oils and cleaning products. Many premium rubber mats are open cell.
Test yours: put a few drops of water on the surface. If it beads and sits, closed cell. If it soaks in and darkens the spot, open cell.
How do you clean a yoga mat?
Mix warm water with a few drops of mild dish soap in a spray bottle. Lightly mist the mat, wipe it down with a soft cloth, then wipe again with a cloth dampened in plain water. Hang or lay it flat to dry completely before rolling it up.
What to avoid, and why
Rubbing alcohol. Common in homemade mat sprays and hard on mat materials. It dries out natural rubber, makes PVC brittle, and can leave a slick residue as it strips the surface texture. On an open cell mat it soaks straight in.
Essential oils. Popular in mat spray recipes and a bad idea. Oil is the enemy of grip, and on an open cell mat it absorbs permanently and leaves a slippery patch. Strong oils can also degrade natural rubber.
Vinegar in strong concentrations. A heavily diluted solution is tolerable on some mats, but acid attacks natural rubber over time. Check the manufacturer's guidance before using it at all.
Bleach and disinfectant sprays. Too harsh for most mat materials, and residue on a surface your face touches is not a good trade. Never mix bleach with vinegar, ammonia, or alcohol in any container.
Hot water and machine washing. Most mats cannot go in a washing machine. Agitation delaminates layers and heat deforms foam. Check the manufacturer, since a few specific mats do allow it.
Direct sunlight for drying. Ultraviolet light degrades rubber and PVC and fades the surface. Dry in the shade.
The routine that actually keeps a mat usable
After every practice: wipe it down with a damp cloth or a light mist of mild solution, then hang it to dry before rolling. Sweat left in a rolled mat is the source of every yoga mat smell.
Weekly for regular practice: a full wipe on both sides. The underside picks up floor dirt and transfers it to the top when rolled.
Monthly, or when it needs it: a deeper clean. For a closed cell mat, that means a bathtub with warm water and a small amount of mild soap, wiped and rinsed thoroughly. For an open cell mat, follow the manufacturer, since soaking one can take days to dry properly.
Roll it with the top surface facing outward for storage, which keeps the grip side from pressing sweat residue into itself.
Why is my yoga mat slippery?
Usually one of three things: a factory film on a brand new mat that wears off with use, oil or lotion residue absorbed into the surface, or a cleaning product that left a slick coating. Wash with mild soap and water, rinse well, and stop using any product containing oils or alcohol.
New mats are often slippery for the first several sessions. That is normal and it breaks in.
Drying is the whole game
A mat rolled up damp will smell, and eventually it will grow mildew between the layers.
Hang it over a railing, a door, or a drying rack, or lay it flat. Not in direct sun. Give it a couple of hours at minimum.
An open cell mat after a deep clean can take a full day. Plan for it rather than rushing it into a bag.
Do not store a mat in a closed bag between practices. The same trapped-moisture principle that governs how to clean a foam roller and resistance bands.
Mat materials, briefly
PVC is durable, closed cell, tolerates mild soap well, and lasts for years.
Natural rubber grips well and is often open cell. It dislikes oils, solvents, prolonged sun, and heat, and it has a natural smell when new that fades.
TPE is lighter, usually closed cell, and takes mild soap fine.
Cork and jute surfaces need a light touch. Wipe rather than soak, and avoid soaking cork, which can lift from its backing.
The manufacturer's care instructions govern all of it. Many premium mats come with a specific do-not-use list.

What cleaning can and cannot do
Cleaning a mat removes sweat, skin cells, and floor soil, and it reduces the bacteria and fungus present on the surface. That is worth doing.
It does not sterilize a mat, and it is not a treatment for a skin condition. If you have a skin infection or a concern about one, that is a question for a doctor rather than a cleaning routine. Use your own mat or a towel over a shared one while anything is healing.
Studio mats get shared. Bringing your own, or laying a mat towel over a borrowed one, is the practical answer.
When to replace a mat
When the surface has worn thin or shiny in the standing spots, when the material is flaking or crumbling, when it has permanent slick patches that cleaning does not fix, or when it holds a smell after a proper wash and full dry.
A mat that has gone thin under the hands and feet has also lost its cushioning, which matters more than the appearance.
Worn mats can often be repurposed as drawer liners, kneeling pads for gardening, or grip pads under rugs and tool boxes, which fits the reuse thinking in our guide to cleaning tools and equipment around the house and to gym gear in how to clean dumbbells and vinyl bench padding.
FAQ
Can you use alcohol to clean a yoga mat?
It is a bad idea on most mats. Alcohol dries out natural rubber, makes PVC brittle over time, and can strip the surface texture and leave the mat slick. On an open cell mat it absorbs into the material. Mild soap and water is the safer choice for nearly every mat.
Can you put a yoga mat in the washing machine?
Almost never. Machine agitation delaminates layered mats and heat deforms foam, and a soaked mat can take days to dry. A few specific mats allow machine washing, so check the manufacturer's instructions. For everything else, wipe or hand wash in a tub with mild soap.
How do you get the smell out of a yoga mat?
Wipe both sides with mild soap and water, rinse the soap off with a clean damp cloth, and let it dry completely flat before rolling. The smell comes from sweat sealed inside a rolled mat, so the lasting fix is drying it fully after every practice rather than rolling it damp.
Should you use essential oils in a yoga mat spray?
No. Oil reduces grip, and on an open cell mat it absorbs permanently and leaves a slippery patch that cannot be cleaned out. Strong essential oils can also degrade natural rubber. Use plain water with a few drops of mild dish soap instead.
How often should you clean a yoga mat?
Wipe it after every practice and give it a full both-sides clean weekly with regular use. A deeper clean once a month or when it visibly needs it is enough. The after-practice wipe and the full drying are what prevent most smell and buildup problems.
Why is my new yoga mat so slippery?
New mats often have a factory film on the surface that wears off over the first several sessions. Wiping it with mild soap and water speeds that up. If a mat stays slippery after break-in and washing, the surface has likely been contaminated with oil or lotion residue.
