High-Performance Penetrating Oil for Rust Removal & Maintenance

Release No.1 is a professional-grade penetrating oil and rust inhibitor that delivers rapid moisture displacement, deep penetration, and long-lasting corrosion protection. Its formulation is trusted by engineers, mechanics, and maintenance professionals for breaking down rust, freeing seized parts, and shielding metal surfaces from the effects of water exposure.

What Is a Dewatering Fluid & Why Use It?

Unlike standard lubricants, dewatering fluids are engineered to displace water from metal and electrical components. Release No.1 forms a protective barrier to stop rust and oxidation, making it an essential tool for industrial, marine, and automotive maintenance where moisture is a constant threat.

Rust Inhibitor for Industrial, Marine & Electrical Use

Use Release No.1 Dewatering Fluid in:

  • Engineering workshops and mechanical repair garages
  • Manufacturing plants and heavy-duty industrial sites
  • Marine engines, transport vehicles, and plant machinery
  • Electrical panels, terminals, and control boxes
  • Fleet maintenance and public sector utilities
  • Battery terminals and rust-prone fasteners

Key Benefits of this Penetrating Oil

  • Fast-acting formula - Quickly loosens rusted, corroded, or seized parts
  • Moisture displacer - Protects electricals and exposed metal
  • Rust inhibition - Leaves a protective barrier to prevent future corrosion
  • Targeted application - Low-mess format reaches into fine threads
  • Multipurpose - Ideal for electrical, mechanical, and marine systems
  • Reliable in harsh conditions - Performs in damp, coastal, or outdoor environments

Important

  • FLAMMABLE liquid and vapour.
  • Maybe fatal if swallowed and enters airways.
  • Causes skin irritation.
  • May cause drowsiness and dizziness.
  • Toxic to aquatic life with long lasting affects.

1️⃣ Use a brush, spray, or immersion method to apply Release No.1 Dewatering Fluid to rusted or moisture-exposed surfaces. Ensure full coverage of joints, threads, and metal components.

2️⃣ Let the fluid soak into seized or corroded parts for several minutes to loosen rust and displace moisture.

3️⃣ Wipe away excess product or proceed with mechanical work once parts are free. The remaining film will offer long-term rust protection.

⚠️ Ensure good ventilation during use, especially in enclosed or low-airflow areas.

What does a rust inhibitor do?

A rust inhibitor prevents moisture from reacting with metal surfaces, reducing oxidation and corrosion. Release No.1 not only stops existing rust but also creates a barrier to block future moisture intrusion.

What are industrial lubricants used for?

Industrial lubricants are used in all mechanical, maintenance and repair applications as a penetrating lubricant, rust, corrosion inhibitor and dewatering fluid. APT’s industrial lubricants are the ideal solution for displacing moisture when used for vehicle maintenance and also as a preventative for long term, dry storage of components, for example:

  • Small individual ferrous and non-ferrous items

  • Assembled parts – ferrous and non-ferrous

  • Complex assemblies with internal surfaces

  • Large simple assembled items

  • Delicate mechanisms

Industrial lubricants are used in all sectors to dismantle rusted, worn parts and removal of moisture from chains etc. This product is used in all heavy-duty industries such as quarries, workshops, shipping and heavy plant.

What is automotive lubricant?

Lubricant used in the automotive industry (and others!) is made up of a blend of penetrating oil and release agents with added graphite. The purpose of PTFE is to lubricate, protect and prevent seizures of metals, whilst also preventing further corrosion and oxidation. It’s commonly used in the engineering sphere to remove engine blocks, heads, studs and bolts and is suitable to stop all machine shop dismantling and plant hire servicing. This can also be used to loosen tyre beards that have become rusted to wheel rims, leaving a protective anti-rust coating for trouble-free future maintenance. Another benefit of this is that it won’t attack plastic cables!

What lubricant to use when drilling metal?

When drilling metal, it’s very common that metal parts can seize up next to one another and become stuck. Metal that has become seized together for some time can corrode and rust, making the problem increasingly worse and more difficult to break apart. PTFE spray and food grade lubricant is a highly stable, non-toxic, water resistant synthetic lubricant for all types of machinery and applications, formulated specifically to give extra lubrication under the most adverse conditions. The properties give excellent lubrication when sprayed onto the substrate material, which is highly durable when applied to a wide range of moving surfaces and components.

What is the best lubricant for metal?

The best lubricant for metal is dependent on the requirements. APT manufacture and supply a range of lubricant sprays and liquids that are suitable for all. Lets break down the lubricants that we provide:

Release No 1 (available in spray and liquid):
Graphite lubricant and penetrating oil that rapidly soaks into the smallest crevices, providing excellent lubrication. It is unsurpassed on seized metals, allowing them to be separated using less force whilst lubricating the surfaces to reduce the change of shearing components. Release No 1 leaves a lasting protective graphite film for added protection against rust, water ingress, damp and corrosion. Release No 1 is ideal for use on during the removal of engine blocks, heads, studs, bolts, all machine shop dismantling and plant hire servicing.

PTFE (available in spray and liquid):
PTFE is an effective synthetic penetrating oil for more difficult rusted parts and seizures. PTFE is ideal where added protection is required after release and higher temperatures are involved in manufacturing or processing operations. This is one of the most effective food-safe lubricants that leaves a reassuring protective film for added defence against rust, water, damp and corrosion elements in harsh operating environments.

What is the best lubricant for metal on metal?

The most suitable lubricant for metal on metal is Release No 1 since it is a highly effective clear penetrating fluid with excellent water displacing properties to provide deep penetration and protection in the most difficult areas whilst lubricating and protecting from further seizure or rusting by displacing water and moisture from all areas. Release No 1 has been specifically formulated to give the desired release with the toughest seizures of metal parts found in all heavy industries such as; quarries, workshops, shipping and heavy lant. The inclusive additives in the formulation effectively searches and penetrates, lubricating and prevents the shearing of threads and giving a quick release of rusted parts.
