electrical contact cleaner

Types of electrical contact cleaner

There are four main types of electrical contact cleaner that are distinguished based on their chemical composition and properties. These are:

• Chlorinated Solvent Cleaners

  These cleaners are often made using solvents such as methylene chloride or perchloroethylene. They are efficient in removing varnish, oils, and other stubborn residues. However, their use has significantly declined in most areas because of environmental concerns and the potential adverse effects on human health. For this reason, alternative cleaners that are less harmful to the environment are being promoted. This doesn't mean that they are no longer effective. When used appropriately, chlorinated cleaners work exceptionally well. They are also non-flammable and have a high evaporation rate, which minimizes the risk of damage to electrical components due to moisture exposure.

• Non-Chlorinated Solvent Cleaners

  These are electrical cleaners that are formulated using solvents such as naphtha, ethanol, or isopropyl alcohol. They are less toxic, making them a preferred choice for many industries. Additionally, they are effective in removing contaminants such as dirt and grease from electrical contacts. Non-chlorinated cleaners are versatile and find applications in various industries, including automotive and telecommunications.

• Alcohol-Based Cleaners

  Manufacturers commonly use isopropyl alcohol in the formulation of electrical contact cleaners under this category. They are effective in removing light contaminants such as dust and do not leave any residue behind. Besides, isopropyl alcohol has excellent properties, including being a fast evaporator and non-conductor. As a result, it is safe for use in cleaning delicate electrical components. Due to their relatively low toxicity, alcohol-based cleaners are widely used.

• Aerosol Spray Cleaners

  These electrical contact cleaners are packaged in aerosol cans. They are designed with the ability to deliver high-pressure jets, allowing for the removal of contaminants from hard-to-reach areas. Besides, they come in various formulations, including alcohol-based and solvent-based, to meet different contact cleaning requirements. Their ability to spray in high pressure makes them suitable for cleaning intricate and delicate electrical components.

Specifications and maintenance of electrical contact cleaner

There are several specifications of electrical contact cleaner that are worth noting. They include:

• Composition and Properties

  Electrical contact cleaners are made of cleaning solvents that have strong capabilities to get rid of contaminants like oils and residues. The cleaners have fast evaporation rates which ensure that there are no residues left on the contacts after cleaning. They are non-conductive, which means they cannot interfere with the electrical signals or the functioning of the equipment. They are also safe for use on different types of materials like metals, plastics, and ceramics.

• Application Method

  There are several ways that an electrical cleaner can be applied to contaminated surfaces. They include being sprayed from an aerosol can, applied with a brush, or poured from a bottle. Whichever application method is used, the applied electrical contact cleaner must be allowed to dwell for some time before being removed or wiped off. They can also be applied using a lint-free cloth.

• Packaging and Formulation

  Electrical contact cleaners are packaged in various ways depending on the manufacturer. They are also available in different formulations. For instance, they could be available as aerosols, liquids, or gels. The packaged electrical contact cleaners are also equipped with specific features like a spray nozzle or a trigger pump that facilitate the application method.

• Compatibility

  Different electrical components are made from different materials. Therefore, when choosing an electrical contact cleaner, it is important to go for one that is compatible with the given electrical component. This is because, although contact cleaners are designed to be used on various electrical components, they might damage or corrode certain materials.

• Health and Safety Considerations

  Electrical contact cleaners have certain specifications that are related to health and safety. They should have low toxicity levels to reduce the impact on humans. They should also have non-flammable properties, which eliminate the risk of fire when being used in electrical components. Additionally, they should be free of harmful chemicals like chlorine or ozone-depleting solvents.

Below are the maintenance tips for electrical cleaners:

• 1. Only trained personnel should use the electrical contact cleaner to avoid accidents and injuries.
• 2. When using an electrical contact cleaner with aerosol spray, users should ensure that they do not spray it onto live electrical components.
• 3. Contact electrical components should be inspected regularly to ensure they are in good condition.
• 4. Users should store electrical contact cleaners in a cool, dry place away from direct sunlight and heat sources.
• 5. The electrical contact cleaner should be used only when necessary. This helps to improve the lifespan of the electrical components.

How to Choose an Electrical Contact Cleaner

With so many options available, choosing the right electrical contact cleaner can be a daunting task. Here are some key factors to consider when selecting an electrical cleaner:

• Type of cleaner: There are different types of electrical contact cleaners, including solvent-based, aerosol sprays, and non-residue cleaners. Solvent-based cleaners are good for removing tough grime and residues. Consider the type of cleaner based on the electrical components' cleaning needs and the dirt type.
• Compatibility: Ensure that the electrical contact cleaner is compatible with the materials used in the components, such as plastics, metals, and coatings. Incompatible cleaners can cause damage, leading to costly repairs and replacements.
• Safety: Consider the safety of the electrical contact cleaner. Look for cleaners with low toxicity levels and those that produce minimal fumes. Cleaners with low toxicity levels are safe for the user and the environment.
• Effectiveness: When choosing an electrical contact cleaner, consider its effectiveness. Look for a cleaner that can easily remove tough grime, dirt, and residues without damaging the electrical components.
• Brand reputation: Consider the cleaner's brand reputation. Look for a well-known brand in the market with quality and reliable cleaning products. Reading online reviews can help people get a cleaner from a reputable brand.
• Price: Consider the electrical contact cleaner price. Electrical cleaners are available at different price points, so it's advisable to have a budget. However, don't compromise on quality.

How to DIY and Replace Electric Contact Cleaner

Switching out or replacing electrical contact cleaner in devices is not complicated, and there are no complex tools required to get the job done. Here is a step-by-step guide on how to DIY and replace electrical contact cleaner:

• 1. Before doing anything, ensure that the device or equipment where the electrical contact cleaner will be replaced is switched off and disconnected from any power source to avoid accidents.
• 2. Gather all the necessary tools that will be needed for this process. These may include safety glasses, lint-free cloths, and the new electrical contact cleaner being applied.
• 3. Inspect the device or equipment to see where the electrical contact cleaner has been used or applied.
• 4. Once the areas where the old cleaner has been applied are identified, use a straw or a thin nozzle to carefully apply the new cleaner into those areas.
• 5. As the cleaner is being applied, electrical users should use a lint-free cloth to wipe away any excess residue.
• 6. After the application, allow the cleaner to fully evaporate before using the device or reconnecting it to the power source.
• 7. Always remember to follow the manufacturer's instructions when applying the cleaner.
