WD-40: The Miracle Product or Rubber Destroyer?


WD-40 is a popular product used to lubricate, clean, and protect metal surfaces. It has been around for over 60 years and is a staple in many garages and workshops. But there have been some questions about whether or not WD-40 harms rubber surfaces.

Does WD-40 damage rubber? WD40 is a safe and effective penetrating oil spray that doesn’t contain harsh chemicals to damage paint, chrome, rubber, glass, or body plastics.

WD 40 Specialist® Silicone Lubricant safely lubricates and protects metal surfaces from corrosion while also providing waterproof protection for non-plastic & vinyl materials with its exceptional silicone content – it’s an all-round win.

This formula is perfect for use on cables and pulleys. It will not stain or stick, so it’s easy to clean up after; plus, the non-staining film ensures your equipment looks good! 

The spray can be applied quickly from -100° F up to 500°+ heat with no risk of leaking because there are tight-fitting lips at each end of this container that prevent any leakage during transport or storage.

Winter can be a tough time to keep your vehicle running smoothly. You might need some help from WD-40! 

When you’re pushing through deep snow or cold temperatures, make sure that the seals on all of its doors are in good shape by spraying them with silicone lubricant before they get too stiff and hard so as not to prevent opening easily during these bothersome seasons where even partial melts don’t come around often enough.

The life of plumbing components is prolonged using WD-40 Specialist Silicone. 

This product can protect plastic pipes, rubber hoses, seals, and washers in industrial environments where they are prone to wear because it’s made with high-quality materials that provide superior performance at a low cost.

How safe is it to use WD40 on rubber?

Oil gradually dissolves rubber, so this can be an issue. WD40 is rated for use on natural or synthetic rubbers, but I’d stay away from using it to make contact with EPDM and other swelling-prone materials because they will just get worse after a short while! 

The best options in terms of resistant fabrics include Nitriles (which means they contain no nitrates), Neoprenes – also known as polyvinyl chloride –and Hypalon, which has been specifically designed by its manufacturer “to resist absorption.

Does WD40 eat rubber?

WD40 is a safe lubricant for rubber. It’s only dangerous to polycarbonate and clear plastics, but since it contains petrochemical ingredients, I wouldn’t recommend spilling them on natural rubbers like Neoprene or Viscose.

Is it okay to wipe rubber hoses with WD-40?

WD 40 is a water-displacing oil spray that’s safe for most materials cars are made of. It won’t attack the metal and can be used on all sorts, from paint to glass or rubber – even if you have an older vehicle with sensitive surfaces!

WD40, a mineral spirit made from petroleum, will soften and swell natural rubber. It’s ok to use on fuel or oil hoses but not coolant ones, so avoid using it near door hinges!

Does WD-40 swell rubber?

WD-40 is a powerful displacing fluid that will cause the gasket to swell when it’s immersed in water. This swelling doesn’t ruin anything but can make rubber or buna ones go out of shape if you spray them with WD 40 and wipe off any excess liquid before applying pressure.

Using buna gaskets in every single can of WD-40 ensures that your product will work perfectly and not let you down when needed. They build cans with this swelling idea in mind, so the valve retaining integrity remains strong after it’s swollen!

What should you not use WD-40 on?

WD-40 is a product that has been around for decades and can be used in thousands of ways. But when it comes to certain tasks, you should avoid using WD 40 because its lubricating properties won’t help.

Door hinges

“WD-40 might not be the answer to your door hinges’ prayers; you should clean them off after using this product; they will turn black and dirty looking over time because of all that dust-attracting stuff. 

Properly wipe away the residue after each application with hot, soapy water. This will help avoid rusting and other damage!

Arthritis relief

Doctors do not recommend using WD-40 as a medicinal treatment for arthritis, and the company itself doesn’t offer any medical advice.

If you happen to come into contact with the product, then it is recommended that soap and water be used for a cleanse. However, other oils or creams can replace this if needed!

Plastics

WD-40 can damage both polycarbonate and clear, tough plastic. Polystyrene is also not a good choice for use with WD 40 as it reacts badly to form harmful chemicals when mixed!

Beware: there are two kinds of plastics that you should avoid using this product – namely those made from PC (polycarbonate)and CPS(clarity couphelone styrened).

Polycarbonate and polystyrene are both commonly used in greenhouses to make transparent plastics. For example, they’re mixed when making styrofoam material, often found on food containers or drink lids, among other things!

Electronics

The use of WD-40 on an iPhone could further damage the device since some iPhones are made of plastic. Plus, it doesn’t help that this substance is also a liquid, and sprays close to electronics might also be hazardous for them! 

Apple recommends not using any solvents or abrasives with their devices, so you don’t risk doing more harm than good if something goes wrong later.

Bike chains

WD-40 is a great product for immediate needs, but it might not work the best if you want something that will last longer. That said, there’s an alternative available called WD 40 BIKE, which can be used as both bike chain lube AND general-purpose grease!

Does WD-40 damage o-rings?

You can clean stuff with WD-40 (but NOT o-rings) and then put a lubricant on whatever. It removes grease, tar, or adhesives to prevent your precious o Ring from drying out in the future! 

When you’re done cleaning all of these items, ensure there’s 100% silicone oil for protection against rusting while also providing extra slip. Hence, they move freely through their intended motions without resistance.
