What You'll Learn
Rubbing alcohol is an effective disinfectant and germicide
Rubbing alcohol, also known as isopropyl alcohol, is a powerful disinfectant and germicide. It is a simple, inexpensive liquid that can be used to kill bacteria, viruses, and fungi. It is also effective against stubborn infections such as MRSA and VRE. Rubbing alcohol is often chosen over hydrogen peroxide, another disinfectant, because it works faster.
Rubbing alcohol is an effective disinfectant for surfaces such as marble, limestone, terrazzo, and glass. It can be used to disinfect countertops and make homemade hand sanitizer. Hospitals use alcohol towelettes to disinfect small surfaces like stethoscopes, scissors, and thermometers. It can also be used to clean manicure tools, tweezers, makeup brushes, and other beauty products.
However, it is important to note that rubbing alcohol should not be used on certain surfaces, such as plastic, rubber, acrylic, polycarbonate, acetate, and vinyl. It can cause these materials to become brittle, discolored, or cloudy, and may lead to cracking or breaking. It is also not suitable for cleaning electronics, as it can strip away protective coatings and cause damage.
In addition, rubbing alcohol should be used with caution due to its high flammability and potential to create harmful fumes. It is important to avoid mixing it with bleach, as this creates chloroform, a toxic compound. When using rubbing alcohol for disinfection, it is recommended to maintain a concentration between 50% and 90% for optimal effectiveness.

It can damage certain plastics and rubbers
While rubbing alcohol is a powerful disinfectant that can kill bacteria and viruses, it can damage certain plastics and rubbers.
Acrylics, a common type of plastic used in aquariums, picture frames, and decorative items, are particularly vulnerable to rubbing alcohol. The alcohol can cause acrylics to become cloudy or discoloured, weakening their structural integrity and leading to cracking or breaking over time.
Other types of plastics that are sensitive to rubbing alcohol include polycarbonate, acetate, and vinyl. These plastics may crack, discolour, or become brittle when exposed to rubbing alcohol.
Rubber parts can also be affected by rubbing alcohol, causing them to dry out, lose elasticity, and become brittle. Prolonged exposure to alcohol can lead to cracking or breaking of rubber items.
Additionally, rubbing alcohol should be avoided when cleaning finished surfaces, such as those painted, shellacked, lacquered, or varnished, as it can liquify and damage these finishes.
When considering the use of rubbing alcohol for disinfection or sterilisation, it is important to be aware of its potential damaging effects on certain plastics and rubbers. Alternative cleaning methods, such as mild soap and water solutions, are recommended for these sensitive materials.

It is not suitable for cleaning electronics
Rubbing alcohol, also known as isopropyl alcohol, is a powerful disinfectant that can kill bacteria, viruses, and fungi. It is a common, inexpensive liquid that can be used to clean surfaces and sterilize equipment. However, it is important to note that rubbing alcohol is not suitable for cleaning electronics.
One reason why rubbing alcohol should be avoided when cleaning electronics is that it can strip away the protective coating on screens, keyboards, and other devices. This leaves them vulnerable to scratches, discoloration, and other damage. The ethanol in rubbing alcohol acts as a solvent, liquifying varnishes or finishes and potentially causing major damage to electronic devices.
Additionally, rubbing alcohol can cause plastic and rubber parts within electronics to dry out and become brittle, leading to cracking or breaking. This is because certain types of plastics, such as polycarbonate, acetate, vinyl, and acrylic, are particularly sensitive to rubbing alcohol. Prolonged exposure to rubbing alcohol can cause these plastics to become cloudy or discolored, weaken their structural integrity, and eventually lead to cracking or breaking.
Furthermore, rubbing alcohol is often mixed with water, which can be detrimental to electronics. Repeated use of rubbing alcohol on electronics can cause them to deteriorate, shorten their lifespan, and result in costly repairs or replacements. Instead of using rubbing alcohol, it is recommended to clean electronics with a microfiber cloth, which is gentle and won't scratch delicate surfaces. Compressed air can also be used to blow dust and debris away from keyboards and other crevices.
While rubbing alcohol can be an effective disinfectant for killing germs, it is crucial to avoid using it on electronics due to the potential for damage and deterioration. Alternative methods, such as microfiber cloths and compressed air, provide safer options for cleaning and maintaining electronic devices.
