Yes, hydrogen peroxide can damage metal. It can cause oxidation, which leads to corrosion and weakening of the metal’s surface. Hydrogen peroxide can form brittle iron oxides, which can flake off if exposed to temperatures and pressures.
Other metals, such as aluminum, will corrode more quickly when exposed to hydrogen peroxide. Unalloyed copper and copper alloy surfaces tend to tarnish in the presence of hydrogen peroxide, fades as the concentration and exposure time decreases, but remains discolored.
It can also corrode or react with some metals, such as titanium,producing hydrogen peroxide byproducts that can be damaging to the metal. Therefore, it is important to note that hydrogen peroxide should not be used on metals that contain copper, titanium or any other sensitive metal.

What happens if you put hydrogen peroxide on metal?
If you put hydrogen peroxide on metal, it can cause corrosion, bleaching, and oxidation. Hydrogen peroxide is a highly reactive chemical and its reaction with the metal surface can be corrosive. Corrosion is an electrochemical process which means that the metal is having an unwanted reaction with the hydrogen peroxide.
Hydrogen peroxide can also cause bleaching of the metal due to the chlorite ions in the solution which can strip some of the metal’s color or make it appear lighter. Furthermore, if left on metal for too long, hydrogen peroxide can cause oxidation.
Oxidation is when the molecules on the surface of the metal react with the hydrogen peroxide and form a coating of oxide on the surface, which can make the metal corrode more quickly. For these reasons, it is best to avoid using hydrogen peroxide on metal surfaces.
What metal reacts with hydrogen peroxide?
Several metals can react with hydrogen peroxide, triggering a wide array of reactions. Some of the most commonly discussed metals with hydrogen peroxide are iron, copper, aluminum, magnesium and their alloys.
While iron and copper readily react with hydrogen peroxide, aluminum and magnesium do not, however their alloys do.
When iron reacts with hydrogen peroxide, iron oxide and water are formed. In the presence of an acid, it will produce iron sulfate and oxygen. These reactions occur when small quantities of hydrogen peroxide are used, since larger amounts will simply corrode the metal instead of reacting.
Copper reacts differently with hydrogen peroxide and forms hydrogen dioxide and cupric oxide, which can be a yellowish powder. The reaction can be slower than with iron, as small flakes of copper take longer to be oxidized.
Aluminum and its alloys do corrode, but do not react directly with the hydrogen peroxide.
Magnesium and its alloys will create an explosive reaction with hydrogen peroxide. The reaction is due to magnesium reacting with the hydrogen peroxide and generating oxygen quickly, creating a harmless spark.
The reaction is more intense as the amount of hydrogen peroxide increases.
What surfaces does hydrogen peroxide damage?
Hydrogen peroxide is an effective cleaning agent, but it also has the potential to cause damage if not used properly. When used in concentrations of 10% or lower, hydrogen peroxide can damage some surfaces, including:
• Carpet and Upholstery: The bleaching action of hydrogen peroxide can lead to discoloration or fading.
• Natural Stone: Natural stone surfaces such as marble or granite can be corroded or etched by hydrogen peroxide.
• Metals: It can cause rusting on metals such as aluminum, brass, bronze, cast iron, and stainless steel.
• Painted Surfaces: Certain types of paints, including latex, enamel, and some oil-based paints, can be damaged by hydrogen peroxide.
• Leather: Leather can be discolored by hydrogen peroxide, and so can other porous substrates like wood and fabric.
It is important to test a hidden area before treating an entire surface with hydrogen peroxide, and always use it with caution. Whenever possible, dilute hydrogen peroxide with water before use, and wear protective gloves and goggles to avoid injury.
How corrosive is hydrogen peroxide?
Hydrogen peroxide is a very corrosive substance. Depending on the concentration and exposure time, it can be highly corrosive to many materials. The higher the concentration, the more corrosive it is.
For example, a 30% concentration of hydrogen peroxide can cause severe corrosion to steel, iron and other metals. Even low concentrations of hydrogen peroxide can corrode stainless steel, aluminum, brass, and copper.
In smaller concentrations, hydrogen peroxide can cause corrosion to some natural materials such as wood and fabrics. The rate of corrosion is significantly reduced when the concentration of hydrogen peroxide is lower.
Its ability to corrode depends on exposure time, temperature, and the material it is exposed to.
When it comes to the environment, hydrogen peroxide can be very corrosive to aquatic life. High concentrations of hydrogen peroxide can deplete oxygen in the water, leading to the destruction of aquatic ecosystems.
Lastly, it can release dangerous free radicals and peroxides, which are highly toxic to many forms of life and can cause a wide range of health problems.
Does hydrogen weaken steel?
No, hydrogen does not weaken steel; in fact, when properly alloyed and processed, hydrogen can strengthen steel. Hydrogen, when introduced into the steel, interacts with the carbon and other alloying elements, such as manganese, nickel, and molybdenum, to create an alloy that is more resistant to creep, fatigue, and wear.
Additionally, hydrogen can form both brittle and ductile precipitates, reducing grain size and edge angle, resulting in a finer-grained and smoother material that is less susceptible to hydrogen embrittlement.
This can help steel retain its strength and durability, even in the harshest of environments. In summary, when used in a controlled manner, hydrogen can be beneficial to steel and not weaken it.
What chemicals will damage stainless steel?
Stainless steel is a strong, durable material that is highly resistant to corrosion and chemical damage, but it isn’t entirely invulnerable. It can be damaged or corroded by a number of different chemicals, including chlorides, acids, and alkalies.
Chlorides, such as sodium chloride and calcium chloride, can cause pitting and corrosion in stainless steel if they are present in high concentrations. Acids, such as sulfuric acid, hydrochloric acid, and nitric acid can cause the steel to corrode and weaken over time.
Alkalies, such as sodium hydroxide and potassium hydroxide, can also corrode stainless steel over time.
Other chemicals to avoid exposing stainless steel to include ammonium hydroxide, phosphoric acid, sodium sulfate, and magnesium hydroxide. All of these can cause corrosion and damage to stainless steel if they are not properly handled.
Finally, it’s important to remember that stainless steel can be easily scratched or stained by dirt, grime, and other foreign materials, so it’s best to keep it clean and protected from abrasive materials or other corrosive elements.
