Wd 40 As A Degreaser

WD-40: More Than Just a Lubricant – Its Surprising Effectiveness as a Degreaser

WD-40, a household name synonymous with lubrication, is often underestimated for its potent degreasing capabilities. While primarily known for its ability to loosen stuck parts and protect against rust and corrosion, its solvent properties make it a surprisingly effective degreaser for various applications. This article delves deep into WD-40's degreasing power, exploring its composition, effectiveness in different scenarios, safety precautions, and comparing it to dedicated degreasers. We'll also address common myths and misconceptions surrounding its use. Understanding its strengths and limitations will empower you to use WD-40 effectively and safely as a degreaser in your home, workshop, or garage.

Understanding WD-40's Composition and Degreasing Mechanism

WD-40's exact formula is a closely guarded trade secret, but it's publicly known to be a blend of several key ingredients: a solvent, a lubricant, a corrosion inhibitor, and a propellant. The solvent is the key component responsible for its degreasing properties. It effectively dissolves grease, grime, and oil, allowing these substances to be easily wiped away. The precise blend of solvents within WD-40 allows it to penetrate deep into crevices and dissolve stubborn grease, making it surprisingly effective even on heavily soiled surfaces. While the lubricating properties are often highlighted, it's the solvent’s ability to break down and lift away the grease that makes it a useful degreaser. This action is facilitated by the propellant, which helps to disperse the solution and reach difficult areas. The corrosion inhibitor helps to prevent rust and corrosion after cleaning, extending the life of the treated surfaces.

WD-40 as a Degreaser: Applications and Effectiveness

WD-40’s versatility extends beyond simple lubrication. Its degreasing properties are surprisingly effective in a wide range of applications:

1. Cleaning Tools and Equipment:

• Gardening Tools: WD-40 can effectively remove caked-on mud, sap, and grease from shovels, hoes, and other gardening tools, restoring their functionality and prolonging their lifespan.
• Workshop Tools: Remove grease and grime from wrenches, screwdrivers, and other workshop tools to improve grip and prevent rust.
• Automotive Tools: Effectively clean grease and oil residue from engine components, spark plugs, and other automotive tools, improving their performance and longevity.

2. Cleaning Household Items:

• Kitchen Appliances: Remove grease buildup from stovetops, oven racks, and grills (after allowing cooling to a safe temperature, of course!). Note: Always test on a small inconspicuous area first to avoid damaging sensitive surfaces.
• Outdoor Furniture: Clean grease and grime from outdoor furniture such as patio chairs and tables, restoring their appearance.
• Garage Door Tracks: Clean away accumulated dirt and grease from garage door tracks, improving their smooth operation.

3. Removing Stubborn Grease and Oil:

• Chainsaw Chains: WD-40's penetrating power helps remove gummed-up grease and sawdust from chainsaw chains, improving their cutting performance.
• Bicycle Chains: Effectively clean and lubricate bicycle chains, removing accumulated dirt and grease.
• Machine Parts: Though not a replacement for specialized industrial degreasers, WD-40 can be useful for cleaning smaller machine parts, particularly when access is limited.

4. Other Applications:

• Removing Stickers and Residue: WD-40 can be used to soften the adhesive of stickers and labels, making them easier to remove, though the residue may require additional cleaning.
• Cleaning Grimy Hands: While not a substitute for proper hand cleaner, it can help remove grease and grime from hands before washing with soap and water.

Comparing WD-40 to Dedicated Degreasers

While WD-40 is effective for many degreasing tasks, it's crucial to understand its limitations when compared to dedicated degreasers.

• Strength: Dedicated degreasers, especially those designed for industrial use, are typically much stronger solvents and can tackle heavier grease and grime more effectively. WD-40 is more of a light-duty degreaser.
• Safety: Dedicated degreasers often contain harsher chemicals and require more stringent safety precautions, including proper ventilation and protective gear. WD-40 is generally safer, but still requires caution.
• Environmental Impact: Dedicated degreasers can have a more significant environmental impact than WD-40. WD-40's formulation, while not environmentally benign, is often considered less harmful.
• Cost: WD-40 is generally more readily available and less expensive than many professional degreasing products.

Choosing between WD-40 and a dedicated degreaser depends on the specific task and the level of soiling. For lighter cleaning tasks and maintenance, WD-40 is often a convenient and effective solution. For heavy-duty degreasing, a dedicated product is usually necessary for optimal results.

Safety Precautions When Using WD-40 as a Degreaser

While WD-40 is generally considered safe for many applications, it’s crucial to follow these safety precautions:

• Ventilation: Always use WD-40 in a well-ventilated area. Inhaling the fumes can be harmful.
• Flammable: WD-40 is highly flammable. Keep it away from open flames, sparks, and hot surfaces.
• Eye Protection: Wear safety glasses to protect your eyes from accidental sprays.
• Skin Contact: Avoid prolonged skin contact. Wash thoroughly with soap and water if contact occurs.
• Ingestion: Keep WD-40 out of reach of children and pets. Accidental ingestion can be harmful.
• Surface Compatibility: Always test WD-40 on a small, inconspicuous area before applying it to a larger surface to ensure it won't damage the material. Some materials, especially plastics and painted surfaces, may be sensitive to the solvents in WD-40.
• Disposal: Dispose of used rags and containers properly according to local regulations.

Debunking WD-40 Myths and Misconceptions

Several myths and misconceptions surround WD-40's use as a degreaser:

• Myth: WD-40 is a lubricant only. While it has lubricating properties, it's also a highly effective solvent.
• Myth: WD-40 is harmful to all plastics. While some plastics may be damaged, many are unaffected. Always test in an inconspicuous area first.
• Myth: WD-40 cleans everything. It's effective for many things but not all cleaning tasks. Heavy-duty grime may require a stronger degreaser.
• Myth: WD-40 can replace all other cleaning products. WD-40 has its niche, but other specialized cleaners are designed for specific tasks.

Frequently Asked Questions (FAQ)

Q: Can I use WD-40 on my car engine?

A: Yes, WD-40 can be used to clean some parts of a car engine, such as removing light grease and grime from external components. However, it's not recommended for cleaning sensitive electronic components or internal engine parts. Always ensure the engine is cool before attempting any cleaning.

Q: Is WD-40 safe for painted surfaces?

A: While generally safe for many painted surfaces, it's always best to test it on a small, inconspicuous area first. Certain paints may be sensitive to the solvents and could be damaged.

Q: Can I use WD-40 on electronic components?

A: It's generally not recommended to use WD-40 on electronic components as it may damage sensitive circuitry. Specialized electronic cleaners are better suited for this task.

Q: How do I remove WD-40 residue after cleaning?

A: After using WD-40, wipe away the loosened grease and grime with a clean cloth. For stubborn residue, you may need to use a slightly damp cloth and mild soap.

Conclusion

WD-40, while best known for its lubricating properties, is a versatile product with surprising effectiveness as a degreaser for various household and workshop applications. Understanding its composition, proper application techniques, and safety precautions is vital to maximizing its benefits.
