Rusted or stuck components represent a common yet frustrating challenge in maintenance and repair tasks across various industries. Whether it's a bolt frozen in place by rust or a hinge refusing to budge due to rust buildup, these issues can bring work to a standstill and require considerable time and effort to resolve. Traditional methods such as brute force or heat application often prove ineffective and can even cause further damage to the components. This is where WD-40 Specialist Penetrant comes in as a powerful solution, with fast-acting contact release to free rusted nuts, bolts, threads, locks, and chains, leaving a protective layer that prevents the recurrence of rust and corrosion. Its advanced formula not only loosens seized parts but also provides long-lasting lubrication, making it an indispensable tool for tackling even the toughest maintenance challenges with ease and efficiency.

The chemical agents present in WD-40 Specialist Penetrant have emerged as indispensable allies for maintenance professionals, providing an effective solution to preserve the integrity and functionality of tools. When faced with rusted components, traditional rust penetrating spray often fall short due to the challenges posed by corrosion. Rust acts as a barrier, preventing parts from moving freely and causing them to become stuck or seized over time. The difficulties encountered in dealing with rusted components can yield the risk of causing damage during removal attempts.

WD-40 Specialist_® Penetrant is specifically formulated to address these challenges. Low surface tension allows the rust penetrant spray to seep into tight spaces, while the chemical composition works to dissolve rust and corrosion, making it easier to free seized parts without causing damage.

The WD-40 Specialist Penetrant has a variety of features and benefits that has proven to be the top choice for addressing rusted or stuck components.

Superior Penetration:

The WD-40 Specialist Penetrant spray is engineered with a powerful formula that penetrates deeply into rust and corrosion, reaching even the tightest spaces to loosen seized parts

Extensive performance testing has confirmed WD-40 Specialist Penetrant’s effectiveness in real-world scenarios by evaluating its ability to penetrate rust, loosen seized parts, and provide long-lasting lubrication. One series of tests involved simulating rusted or stuck components commonly found in automotive and industrial settings, such as bolts, nuts, hinges, and shafts exposed to corrosive environments or seized due to rust buildup. The WD-40 Specialist Penetrant was applied according to usage instructions and compared to leading competitors.

Corrosion Protection:

The WD-40 Specialist_® Penetrant not only removes existing rust but also forms a protective barrier against future rust, helping to prolong the life of treated components while also protecting against rust and corrosion.

Versatile Application:

Whether it's automotive, industrial, or marine, WD-40 Specialist Penetrant is versatile enough to tackle a The WD-40 Specialist Penetrant uses the WD-40 EZ Reach spray system for hard to reach areas and the Smart Straw that is designed to give you precise application or maximum coverage. Use the Smart Straw to reach tight crevices and small openings or leave the straw in the down position for the classic innovative spray nozzle.  These spray systems are particularly handy for getting into hard-to-reach places.

Low Odor Formula:

The WD-40 Specialist Penetrant formula is designed to have a low odor, making it more pleasant to use compared to other related products on the market.

Preparation is Key:

Before using a rust penetrant spray, clean the surface of the rusted or stuck component to remove any dirt, debris, or loose rust. This will allow the penetrant to better reach the affected area and work more effectively. Spray the affected area generously, ensuring thorough coverage. Allow the rust penetrant spray to penetrate deeply into rust and corrosion, giving it time to work its magic. For persistent rust or corrosion, allow the penetrant plenty of time to work. Depending on the severity of the rust, it may take several minutes for the penetrant to fully penetrate and loosen seized parts.

Use Mechanical Assistance:

In some cases, mechanical assistance may be necessary to help loosen components. After applying the rust penetrating spray, use a wrench, pliers, or other tools to gently attempt to turn or manipulate the stuck part. Avoid using excessive force, as this could cause damage

The WD-40 Specialist_® Penetrant is engineered to quickly break through rust, grease, and grime, making it faster at loosening stuck parts compared to any other rust penetrating spray products on the market. Unlike some rust penetrant spray that evaporate or run off after application, the WD-40 Specialist Penetrant leaves a long-lasting, non-evaporating formula that continues to provide protection. The penetrant utilizes capillary action to wick along metal surfaces beneath moisture and grease layers, displacing them and getting directly to problem areas where corrosion occurs.
