The novel coronavirus can remain viable on plastic for up to three days. To kill coronavirus on plastic, disinfectant is recommended. Bleach solutions, alcohol solutions, and hydrogen peroxide are all effective methods for disinfecting surfaces. Bleach solutions can be made by mixing half a cup of bleach with one gallon of water. Alcohol solutions should contain at least 70% alcohol and be left on surfaces for 30 seconds to 30 minutes. Hydrogen peroxide can be sprayed on surfaces and wiped off after one minute. Additionally, researchers at the University of Jyväskylä in Finland have found that resin-treated plastics can quickly deactivate viruses, including the SARS-CoV-2 virus.

Bleach solutions: Dip non-porous plastic items in a diluted bleach solution for 30 seconds
Bleach solutions are an effective way to kill the coronavirus on non-porous plastic items. Bleach is harsh on the skin, so it should not be used as a substitute for hand-washing or hand sanitiser.
To make a bleach solution, mix half a cup of bleach with one gallon of water. Dip non-porous plastic items, such as plastic toys, into the diluted bleach solution for 30 seconds. For household surfaces that won't be damaged by bleach, allow the solution to sit for 10 or more minutes.
It is important to note that you should not immediately wipe off the bleach solution after applying it to a surface. Let it sit long enough to kill viruses first. The U.S. Centers for Disease Control and Prevention recommends daily disinfection of frequently touched surfaces such as doorknobs, light switches, countertops, handles, phones, and keyboards.
While bleach solutions are effective, they are not the only option for disinfecting surfaces. Alcohol solutions with at least 70% alcohol can also be used. Additionally, researchers at the University of Jyväskylä in Finland have found that resin-treated plastics can quickly deactivate viruses, which could be promising for developing antiviral surfaces.

Alcohol solutions: Use a 70% alcohol solution on surfaces for 30 seconds to kill viruses
Alcohol solutions are an effective way to kill the coronavirus on plastic surfaces. It is recommended to use a 70% alcohol solution on surfaces for 30 seconds to ensure the deactivation of viruses. This concentration is strong enough to kill coronaviruses and other germs, but not so strong that it evaporates too quickly to be effective.
It is important to note that a 70% alcohol solution with water is harsh on the skin and should not be used as a substitute for handwashing or hand sanitizer. Instead, it should be used on surfaces such as tables, doorknobs, light switches, countertops, handles, desks, phones, keyboards, toilets, faucets, and sinks. These high-touch surfaces should be disinfected daily, especially if someone in your household is experiencing flu-like symptoms.
To use an alcohol solution effectively, clean the surface with detergent and water first. Then, apply the undiluted 70% alcohol solution to the surface and let it sit for 30 seconds before wiping it off. This will ensure that the virus is killed and reduce the risk of infection.
While alcohol solutions are effective, they may not be suitable for all plastic surfaces. Alcohol can discolor some plastics, so it is important to test it on a small area first. Additionally, it is worth noting that some household chemicals should not be mixed, as they can create dangerous and poisonous gases.

Hydrogen peroxide: Spray 3% hydrogen peroxide on surfaces, leave for a minute, then wipe
Hydrogen peroxide is a common household chemical with many uses. It is a great alternative to bleach and won't leave your house smelling like a swimming pool. It is also inexpensive and effective. According to the Center for Disease Control and Prevention, a 3% solution of hydrogen peroxide is effective in killing the rhinovirus, which is harder to kill than the coronavirus, so it can be used to break down the coronavirus as well.
To use hydrogen peroxide to kill coronavirus on plastic, first, clean any visible dirt or grime off the area with plain soap and water. Then, pour the 3% hydrogen peroxide into a spray bottle and spray it onto the plastic surface. Leave the solution on the surface for one minute and then wipe it off with a cloth.
Hydrogen peroxide can be used in many other ways as well. It can be used to clean your toothbrush by dipping it in peroxide for five minutes and then rinsing with water. It can also be used to remove mould and mildew in your dishwasher by spraying it in the intricate parts of the dishwasher where moisture can linger. It can even be used to treat water in your pond to reduce or remove harmful algae.
However, it is important to note that hydrogen peroxide should be used with caution. It should be used in a well-ventilated area and gloves should be worn. It can be toxic if inhaled and can irritate the skin and eyes. It should also be kept in a locked cabinet out of reach of children and pets as it can cause serious side effects if ingested.

Tea tree oil: Studies suggest it can kill some viruses, but no evidence for coronavirus
Tea tree oil, or melaleuca oil, is believed by some to be antibacterial, antiviral, and even anti-coronavirus. However, while tea tree oil has been shown in some studies to be effective against certain viruses, there is currently no evidence to support its use against the novel coronavirus.
The belief in the antiviral properties of tea tree oil is not without merit. Some people have attested to the healing effects of tea tree oil, claiming improvements in their digestive, nervous, and respiratory systems, as well as relief from eczema and acne.
The lack of evidence regarding the effectiveness of tea tree oil against the novel coronavirus may be due to the recent discovery of the virus. Scientists assume that what works against other coronaviruses will also work against this strain. However, until specific studies are conducted, it is unclear whether tea tree oil can kill the novel coronavirus on plastic or any other surface.
To effectively kill the novel coronavirus on plastic surfaces, it is recommended to use disinfectants, diluted bleach solutions, or alcohol solutions with at least 70% alcohol. These solutions should be left on the surfaces for at least 30 seconds to a few minutes before wiping them off. It is important to note that some of these solutions can be harsh on the skin, so it is recommended to prioritize hand-washing and the use of hand sanitizer.

Resin-treated plastics: Research shows resin-treated plastics can quickly deactivate viruses
Resin-treated plastics are an effective way to kill the coronavirus on plastic surfaces. Research conducted by Professor Varpu Marjomäki, a Cell and Molecular Biology expert at the University of Jyväskylä in Finland, has shown promising results in this regard. The study found that viruses can remain active on solid surfaces for extended periods, increasing the risk of infection. However, resin-treated plastics demonstrated good antiviral activity within 15 minutes of contact and excellent efficacy after 30 minutes.
The research is part of the BIOPROT project, which aims to develop bio-based antiviral materials for protective gear. The project focuses on creating surfaces with antiviral functionality that can be used in various settings, such as restaurants, public transport, and stores, where viruses can easily spread and remain infectious for long periods.
The Nanoscience Center of the University of Jyväskylä studied resin-embedded plastic surfaces against both the seasonal human coronavirus and the SARS-CoV-2 virus. They found that untreated plastic surfaces allowed viruses to stay infective for more than two days, while resin-treated plastics showed a significant reduction in viral activity within a much shorter time frame.
While resin-treated plastics offer an innovative approach to combating viral transmission, it is essential to follow other preventative measures as well. Regular cleaning and disinfection of frequently touched surfaces are crucial in preventing the spread of coronavirus. The Centers for Disease Control and Prevention (CDC) recommends using liquid disinfectant products, detergent or soap and water on dirty surfaces, and allowing disinfectants to remain on surfaces for a sufficient amount of time before wiping them off.
