The Covid-19 pandemic has changed our daily routines and made us more cautious about hygiene. One question that has come up is whether ironing clothes can actually kill the virus causing Covid-19. This post explores this intriguing question, detailing the science behind heat treatment, the effectiveness of ironing, and practical tips to keep our environments safe.
The Science Behind Covid-19 Transmission
To understand whether ironing can eliminate Covid-19, we first need to know how the virus spreads. The primary way it spreads is through respiratory droplets when an infected person coughs, sneezes, talks, or breathes. These droplets can land on surfaces, including clothes, which raises the risk of contact-based transmission.
Research indicates that the SARS-CoV-2 virus can survive on fabrics like cotton and polyester for hours or even days. For example, a study by the New England Journal of Medicine found that the virus remained viable on plastic and stainless steel for up to 72 hours but was less stable on cloth surfaces. This leads to the important question: Can heat from ironing neutralize the virus?
How Heat Affects Viruses
Ironing usually heats to temperatures between 130°C and 200°C (266°F to 392°F), depending on the fabric. Many pathogens, including SARS-CoV-2, cannot survive these temperatures. Research shows that most viruses become inactive at temperatures above 60°C (140°F) if exposed for a sufficient duration.
This brings us back to our main concern: Does ironing for a brief period eliminate the virus effectively? Data suggests that prolonged exposure to high temperatures can deactivate the virus on fabrics. However, quickly gliding an iron over clothes won’t guarantee complete elimination.
Practical Measures for Ironing Clothes
If you want to use ironing as a way to help sanitize your clothes, follow these key practices:
Choose the Right Settings: Adjust your iron to the appropriate temperature for the fabric. Using high heat on sensitive fabrics could damage them, so be cautious to avoid ineffectiveness.
Cover and Steam: Use a cloth cover while ironing to help maintain high heat and protect the fabric. Additionally, consider steaming as it introduces moisture that can enhance virus inactivation.
Time It Right: Move the iron over each section of the fabric for at least 10-15 seconds. Focus on parts of clothing that are more likely to come into contact with skin, like collars and cuffs, ensuring thorough heating.
General Hygiene Practices: Incorporate ironing as part of a complete hygiene routine. Wash clothes regularly at high temperatures and continue following public health guidelines.

Limitations of Ironing Alone
While ironing can effectively reduce the presence of Covid-19, it should not be relied on as a sole method for maintaining hygiene. Other organisms, such as bacteria or fungi, may still present risks. Therefore, it’s vital to combine multiple methods like washing, ironing, and sanitizing.
Understanding the limitations of ironing in your overall hygiene plan is crucial. It’s not foolproof; ironing may not eliminate all contaminants, especially if clothes have been exposed to infected surfaces.
Additional Cleaning and Disinfection Methods
To enhance your clothing and environment's safety, consider these effective methods:
Regular Washing with Soap and Hot Water: Wash your clothes in a washing machine with hot water and detergent to significantly reduce viral load.
Using Fabric Sanitizers: Utilize fabric sanitizing sprays shown to be effective against viruses. Always follow the manufacturer's instructions for best results.
Air Drying: Whenever possible, allow clothes to air dry outside. Sunlight has natural properties that can help disinfect clothing due to its UV rays.

The Role of Ironing in a Broader Context
While the idea that ironing could help eliminate Covid-19 is interesting, it is vital to recognize that no single method ensures safety. An effective approach combines washing, ironing, and other sanitation practices to minimize risks.
As we navigate through the pandemic, we should also be mindful of the types of materials we frequently touch. Opting for fabrics that are machine-washable or easy to clean can vastly improve your hygiene practices.
Final Thoughts
So, does ironing kill Covid-19? Yes, it can significantly reduce the virus on clothing if done correctly. However, it should be part of a larger hygiene strategy that includes regular washing and additional sanitizing measures.
By understanding how the heat from ironing affects the virus and integrating it with other cleanliness practices, we can take proactive steps towards safer living. Staying informed and practicing comprehensive hygiene is essential in the ongoing battle against Covid-19.
