What should you not use WD-40 on?

WD-40 is a versatile and widely used household product known for its ability to address various issues. However, despite its effectiveness for many applications, there are certain surfaces and items on which you should avoid using WD-40 due to potential damage or adverse effects. In this article, we’ll discuss what you should not use WD-40 on and explore alternative solutions for those situations.

1. Electronics and Electrical Components

WD-40 is not suitable for use on electronics or electrical components. It can leave behind a residue that may damage delicate circuitry, cause short circuits, or interfere with the functionality of electronic devices. When cleaning or lubricating electronics, use specialized electronics cleaners or contact cleaners designed for these purposes.

2. Rubber and Plastic Components

While WD-40 can be used on some rubber and plastic surfaces, it’s essential to exercise caution. Extended exposure to WD-40 can degrade or soften certain types of rubber and plastic, leading to cracking or deterioration. Avoid using WD-40 on rubber or plastic parts of your vehicle, such as door seals or trim. Instead, use dedicated rubber or plastic protectants.

3. Bicycle Chains and Gears

WD-40 should not be used as a long-term lubricant for bicycle chains and gears. Although it can provide temporary lubrication, it tends to attract dust and dirt, leading to increased wear and tear. Instead, use a bicycle-specific chain lubricant that is designed to provide lasting lubrication while repelling contaminants.

4. Painted Surfaces

Avoid using WD-40 on painted surfaces, as it can potentially damage or strip paint. If you need to remove a sticky residue from paint, consider using a specialized adhesive remover or a mixture of mild soap and water.

5. Food Preparation Surfaces

Never use WD-40 on surfaces that come into contact with food or food preparation, such as countertops, cutting boards, or kitchen utensils. WD-40 is not food-safe and should be kept away from areas where food is prepared. Use food-grade cleaning products for kitchen surfaces.

6. Brake Systems and Discs

It is crucial to avoid using WD-40 on brake systems, including brake discs and pads. The residue left behind by WD-40 can compromise brake performance and safety. Always use brake-specific cleaners and lubricants when working on brake components.

7. Firearms

WD-40 should not be used as a firearm lubricant. Firearms require specialized lubricants and cleaning products designed for their unique needs. Using WD-40 on firearms can result in reduced reliability and potential safety hazards.

8. Musical Instruments

While WD-40 can be used for some instrument maintenance tasks, it should not be applied directly to the surfaces of musical instruments, especially those made of wood. It may damage the finish or affect the sound quality. Instead, use instrument-specific cleaning and maintenance products.

9. Clothing and Fabric

WD-40 is not suitable for removing stains from clothing or fabric. It can leave an oily residue that is difficult to remove. Use appropriate fabric stain removers or follow garment care instructions for stain removal.

10. Sealed Bearings

WD-40 should not be used on sealed bearings. It may break down the seals and allow contaminants to enter, ultimately causing bearing failure. Use appropriate bearing lubricants recommended by the manufacturer.

In conclusion, while WD-40 is a versatile product with numerous applications, it is essential to be mindful of its limitations and potential adverse effects on specific surfaces and items. When in doubt, consult manufacturer recommendations or use specialized products designed for the intended purpose to ensure the safety and longevity
