How Long Does Staph Live on Surfaces, Clothes and Towels?

The short answer

Longer than most people expect. The CDC says MRSA, a type of staph, can survive on some surfaces, like towels, razors and furniture, for hours, days or even weeks.¹ Under lab conditions, researchers have found staph lasting for months.²

That doesn’t mean every doorknob is a threat. Staph on a surface has to reach broken skin to cause an infection. Knowing where it lingers simply helps you clean the right things. Here’s what the research says, what it means for your home, and which cleaning steps are worth your time.

Hard surfaces

A large review of how long germs survive outside the body found that Staphylococcus aureus, including MRSA, can persist for months on dry surfaces. Resistant and non-resistant staph lasted about the same.²

The same review found that survival depends on conditions. Staph tended to last longer when:²

• Temperatures were cool
• More bacteria were left behind to begin with
• Body fluids, like blood or mucus, were on the surface too

In other words, a cool, rarely cleaned surface with a smear of dried fluid on it is where staph can hang on longest. Lab tests often use conditions that favor the germ, so real-world survival is usually shorter. Still, it’s a good reason to clean spots that many hands touch, such as keyboards, desks and gym equipment.¹

The review’s authors concluded that without regular disinfection, surfaces can keep passing germs to people for a long time.² That’s one reason hospitals clean patient rooms so carefully.

Clothes, towels and bedding

Fabric can hold onto staph, too. In a lab study of common hospital fabrics, every staph sample survived for at least a day. On polyester, staph lasted anywhere from 1 to 56 days, and on plastic some samples lasted more than 90 days.³ The study focused on items like privacy curtains, lab coats and scrubs, which many people touch in a day.³ At home, the same idea applies to bath towels, gym clothes and bedding that get reused.

Towels are a special case. They touch a lot of skin, and people tend to share them. That’s why the CDC lists towels, washcloths and clothing among the items no one should share.⁴ For step-by-step tips, read our guide to laundry and staph.

What this means for your risk

Surfaces are only one part of the picture. Staph most often reaches a wound through hands, skin contact or shared personal items. A germ sitting on a counter can’t cause an infection until something carries it to broken skin.

Hands are usually that something. A towel or doorknob matters most when someone touches it and then touches a cut, scrape or sore. Regular handwashing helps break that chain.

This is also why ordinary cleaning is usually enough. When MRSA shows up at a school, the CDC says routine cleaning is enough in most cases, and schools generally don’t need to close to disinfect.⁵

Cleaning habits that help

Focus on things that touch bare skin or get handled by lots of people.

• Wash towels, uniforms and workout clothes after each use, and dry them completely in a dryer rather than on a line.⁴
• Wash your hands after handling dirty laundry.⁶
• Wash laundry before anyone else uses it, if someone in the home has a skin infection.⁶
• Clean high-touch surfaces often. If you disinfect, use an EPA-registered product that lists MRSA on the label, and follow the label’s directions, including how long it needs to stay wet on the surface.¹
• Put a towel or clothing between your skin and shared gym benches and equipment.⁴
• Keep your own towel, razor and washcloth to yourself.⁴

When to see a doctor

Clean surfaces help, but they can’t replace medical care. Call a doctor if you notice:

• A bump or cut that is red, swollen, warm, painful or draining pus¹
• Fever with a skin infection¹
• Redness that spreads, or a wound that isn’t healing
• Repeat skin infections in your household

Get urgent care or call 911 for a fever with fast-spreading redness, confusion, trouble breathing, or a baby who seems very sick.

For older adults and people with diabetes or a weakened immune system, call the doctor sooner rather than later. If staph keeps coming back at home, your doctor can help figure out why and what to do next. And don’t squeeze or drain a bump yourself.
