Electrical contact cleaner is a solvent cleaner designed to remove contamination from electrical contacts. It is used to clean connectors, switches, and other electrical and electronic components with moving surface contacts. Electrical contact cleaners are available in different types, but most contain isopropyl alcohol, a colorless, flammable compound. Alcohol-based electrical contact cleaners are generally considered safer and more effective than using water and soap, which can leave behind a residue.
| Characteristics | Values |
|---|---|
| Purpose | Remove or prevent the build-up of oxides, grease, oil, dirt, dust, grime, rust, or other unwanted substances on the conductive surfaces of connectors, switches, and other electronic components with moving surface contacts |
| Type of substance | Contact cleaner is a marketing label for a chemical or a mixture of chemicals |
| Ingredients | Most electrical contact cleaners contain isopropyl alcohol. Other ingredients include oleic acid, hydrocarbon solvents, lubricants, oils, and silicone oil. |
| Function | Improve connection quality, reduce contact resistance, minimize wetting current, and prevent connectivity issues |
| Application | Electrical contact cleaners are applied using pressurized aerosol packaging to provide a forceful spray that reaches into all the crevices of the connectors. |
| Evaporation | Some contact cleaners are designed to evaporate completely and rapidly, leaving no residue. |
| Plastic compatibility | Electrical contact cleaners should be chosen carefully as some plastics are sensitive to harsh solvents. |

Electrical contact cleaners are often made of isopropyl alcohol
Isopropyl alcohol is a common ingredient in electrical contact cleaners because it evaporates quickly and completely, leaving no residue behind. This is important because any residue left on electrical components can attract dust and dirt, leading to a build-up of contaminants that can interfere with the flow of electricity.
Isopropyl alcohol is also relatively safe to use on electrical components. While it is flammable and can burn if set alight, it is not as explosive as pure alcohol, which is too expensive to be used in large quantities. Instead, manufacturers often mix alcohol with other components to minimize cost and danger.
In addition to isopropyl alcohol, electrical contact cleaners may also contain additives such as lubricants or corrosion inhibitors. These additives are designed to keep the contacts sliding smoothly and prevent oxidation and corrosion. However, these additives may not always be welcome, as they can attract dust and dirt over time.
Overall, isopropyl alcohol is a key ingredient in many electrical contact cleaners due to its effectiveness, safety, and ability to evaporate quickly and completely, leaving no residue behind.

They may also contain lubricants to prevent oxidation
Electrical contact cleaners are used to clean contaminants off electrical components. Contaminants such as dust, dirt, grease, and oxidation can increase electrical resistance in contact areas, reducing or interrupting the current flow. This can affect the performance of the device and potentially lead to safety hazards.
Contact cleaners are typically chemical mixtures, often containing isopropyl alcohol, which is a colorless, flammable compound. This alcohol is a powerful sanitizing agent that can safely and effectively clean electrical components by dissolving dirt, dust, and grime. It is also fast-evaporating, leaving no residue behind.
Some contact cleaners may also contain lubricants. While lubricants themselves are not recommended as contact cleaners due to the potential for unsuitable residue, certain lubricants can work well when included in a contact cleaner formula. These lubricants can help prevent oxidation and corrosion while improving contact and conductivity. For instance, silicone-based lubricants are compatible with metal, rubber, and plastic, and can fill connector gaps, provide grounding for circuits, and control static discharge.
The inclusion of lubricants in contact cleaners can be beneficial, but it is important to consider the specific application and equipment. In some cases, lubricants may be considered contaminants, especially if they attract dust and dirt or migrate within the equipment, such as with silicone oil. Therefore, it is recommended to test a new contact cleaner before use on any questionable applications or expensive equipment.
Overall, while lubricants can be a useful addition to electrical contact cleaners, it is crucial to select an appropriate product for the specific application to ensure effective cleaning and protection without introducing new contaminants.

Some cleaners contain oils, like silicone oil, to prevent oxidation
Electrical contact cleaners are products designed to clean contaminants off electrical components. They are also known as switch cleaners. Electrical contact cleaners can be used on a variety of electrical components, including connectors, switches, and other electrical and electronic components with moving surface contacts. The goal is to quickly remove insulative contamination, avoiding a lot of wiping and scrubbing.
Contact cleaners are usually chemical or a mixture of chemicals. They typically come in pressurized aerosol packaging for convenience and to provide a forceful spray that reaches into all the crevices of the connectors. Some contact cleaners are designed to evaporate completely and rapidly, leaving no residue. Others may contain lubricants. Lubricants themselves should not necessarily be used as contact cleaners, but appropriate lubricants may work well as contact cleaners.
Some electrical contact cleaners contain isopropyl alcohol, a colorless, flammable compound. Alcohol-based electrical contact cleaners offer a safer and more effective cleaning solution. However, some contact cleaners contain oils, like silicone oil, to prevent oxidation. Silicone oil tends to migrate and may be considered a contamination in some cases. It is important to note that rubber, silicone, or other seals or gaskets made of elastomeric (soft) materials can be damaged by harsh solvents. Therefore, it is recommended to test a new contact cleaner before use on any questionable applications or expensive equipment.
CircuitWorks® Silver Conductive Grease is an example of an electrical contact cleaner that utilizes an advanced silicone lubricant. It is compatible with metal, rubber, and plastic and can be used to fill connector gaps, provide grounding for circuits, and control static discharge. This product provides protection from moisture, oxidation, and other environmental hazards while maximizing electrical conductivity through the contacts.

Electrical contact cleaners are flammable due to containing alcohol and hydrocarbon solvents
Electrical contact cleaners are typically used to remove or prevent the build-up of oxides or other unwanted substances on the conductive surfaces of connectors, switches, and other electronic components. They are designed to quickly remove insulative contamination without requiring much wiping or scrubbing. Electrical contact cleaners are often sold in pressurized aerosol packaging to provide a forceful spray that can reach into all the crevices of the connectors.
In addition to alcohol, hydrocarbon solvents are also present in electrical contact cleaners. These solvents can be harsh and are known to damage sensitive plastics and gasketing materials found in electrical devices. The use of these flammable solvents poses safety hazards, particularly if there is inadequate ventilation or if there are open flames, sparks, or hot surfaces nearby.
To mitigate these risks, it is recommended to use non-flammable contact cleaners, although they may be offered at a higher price point. Proper safety precautions, such as ensuring adequate ventilation and avoiding ignition sources, are crucial when working with flammable electrical contact cleaners.

While contact cleaners are effective, they can be expensive and may contain flammable substances that pose safety hazards.
Other alternatives to electrical contact cleaners include using isopropyl alcohol, which is effective but must be used outdoors and can damage finishes if not properly handled. Some people also use brake cleaner, but it may not be the best option for long-term switch contact cleaning. These alternatives offer varying levels of effectiveness and safety, and some may be more suitable for specific applications than others.
