What Is Hydrogen Peroxide? 

First, let’s get to the point of what not to do with hydrogen peroxide so you do not make certain mistakes when using it.

• Do not ingest hydrogen peroxide: Hydrogen peroxide is a highly reactive compound that can cause harm if ingested. It can irritate and damage the lining of the gastrointestinal tract, leading to symptoms such as nausea, vomiting, abdominal pain, and even internal burns. In severe cases, it can cause the formation of gas bubbles, which can further damage tissues or lead to embolisms.
• Do not apply undiluted hydrogen peroxide to wounds: Hydrogen peroxide is commonly used as an antiseptic to clean wounds. However, it should always be properly diluted before use. Applying undiluted hydrogen peroxide to a wound can delay the healing process by damaging healthy tissues and cells. It can also impede the body’s natural wound-healing mechanisms.

For example, if you have a minor cut or scrape, it is best to dilute hydrogen peroxide with water in a 1:1 ratio and then gently clean the wound using a sterile cotton ball or swab.

• Do not mix hydrogen peroxide with vinegar or other acidic substances: Mixing hydrogen peroxide with acidic substances, such as vinegar, lemon juice, or citric acid, can create a chemical reaction that produces peracetic acid. Peracetic acid is a corrosive compound that can cause respiratory irritation, eye damage, and skin burns. The fumes generated from this mixture can be harmful if inhaled.

For example, using a mixture of hydrogen peroxide and vinegar as a cleaning solution may seem like a natural alternative, but it can be hazardous. It’s best to use these substances separately or follow specific instructions provided by reputable sources if a mixture is deemed safe.

• Do not use hydrogen peroxide as a contact lens solution: Hydrogen peroxide should never be used as a substitute for contact lens solution. Contact lens solutions are specially formulated to disinfect lenses and maintain their moisture levels. Hydrogen peroxide, on the other hand, can cause severe eye irritation and burning if it comes into direct contact with the eyes. It is not designed for direct use on the delicate tissues of the eyes.

For proper lens care, always follow the manufacturer’s instructions and use the recommended contact lens solution specifically formulated for cleaning and storing lenses.

• Do not use hydrogen peroxide on colored fabrics: Hydrogen peroxide has bleaching properties, which means it can remove or fade colors from fabrics. If you use undiluted hydrogen peroxide on colored clothing or materials, it may result in discolored patches or lightened areas. To avoid damaging your colored fabrics, it’s best to refrain from using hydrogen peroxide unless you specifically intend to remove a stain or discoloration.

For instance, if you accidentally spill hydrogen peroxide on a colored garment, it’s advisable to rinse it immediately with water to minimize any potential discoloration. However, for persistent stains or delicate fabrics, it’s better to consult professional cleaners.

• Do not mix hydrogen peroxide with bleach: Mixing hydrogen peroxide with bleach can lead to a chemical reaction that produces toxic gases, such as chlorine gas. Chlorine gas is highly dangerous and can cause respiratory distress, eye irritation, and other severe health problems. Mixing these substances can also result in the formation of other harmful compounds that pose risks to your health.

It is crucial to keep hydrogen peroxide and bleach separate and use them for their intended purposes. If you need to disinfect surfaces, use one or the other, but never mix them together.

• Do not use hydrogen peroxide as a mouthwash: While hydrogen peroxide has antimicrobial properties and may be effective against certain oral bacteria, it is not safe to use as a mouthwash. Using undiluted hydrogen peroxide in your mouth can cause irritation and damage to the delicate tissues, including your gums and mucous membranes. It can disrupt the natural balance of oral bacteria and potentially lead to oral health issues.

For maintaining good oral hygiene, it is recommended to use an ADA-approved mouthwash specifically designed for oral use and follow the instructions provided.

• Do not store hydrogen peroxide in inappropriate containers: Hydrogen peroxide should always be stored in a tightly sealed, opaque container that is specifically designed for storing chemicals. Using inappropriate containers, such as old soda bottles or containers without proper seals, can lead to increased pressure buildup within the container. This pressure buildup can cause leakage or even result in the container bursting, potentially leading to accidents or chemical exposure.

To ensure safety, store hydrogen peroxide in its original container or transfer it to an appropriate storage container that is clearly labeled and sealed tightly.

• Do not use hydrogen peroxide on delicate surfaces: Hydrogen peroxide can have a corrosive effect on certain surfaces, especially delicate or porous materials like marble, granite, natural stone, or certain metals. It can cause discoloration, fading, or etching. To prevent damage, it’s best to avoid using hydrogen peroxide directly on these surfaces.

If you need to clean delicate surfaces, it’s advisable to use gentle, non-corrosive cleaning agents or consult professionals who specialize in cleaning and maintaining such surfaces.

• Do not use hydrogen peroxide as a hair lightener without caution: Hydrogen peroxide is commonly used as a hair lightening agent, especially in hair bleaching processes. However, excessive or improper use can damage the hair shaft and scalp. Hydrogen peroxide can strip the hair of its natural oils, leaving it dry, brittle, and prone to breakage. It can also cause scalp irritation, burning, or chemical burns if left on the skin for too long.

If you choose to use hydrogen peroxide for hair-lightening purposes, it’s important to follow proper instructions, perform a patch test on a small section of hair and skin, and consider seeking professional advice to minimize the risk of damage.

Always exercise caution and follow appropriate guidelines when handling hydrogen peroxide to avoid potential risks and harm. If you have specific concerns or questions about its usage, consulting a medical professional or seeking expert advice is recommended.

With all that said, hydrogen peroxide is a versatile household product that can be used for various cleaning, disinfecting, and stain-removing purposes.
