Introduction

Industrial equipment and metal components are often exposed to two common maintenance problems at the same time: oil and grease buildup and the risk of rust and corrosion.

Before equipment can be inspected, repaired, painted or maintained, oil and grease may need to be removed. However, cleaning metal surfaces can also leave them exposed to moisture and other conditions that contribute to corrosion.

This is where an antirust degreaser can be useful.

An antirust degreaser is designed to support the cleaning of oily or greasy surfaces while also helping address the need for rust or corrosion protection.

In this guide, we explain what an antirust degreaser is, how it works, where it can be used and how to choose the right product for metal surfaces.

What is an Antirust Degreaser?

An antirust degreaser is a specialised industrial cleaning product designed for degreasing applications where rust prevention or corrosion protection is also an important consideration.

Unlike a standard degreaser that focuses mainly on removing oil and grease, an antirust degreaser is positioned for applications involving both:

• Oil and grease removal
• Cleaning metal surfaces
• Equipment maintenance
• Surface preparation
• Rust and corrosion management

The EPOCHEM product range includes EPOCHEM 501 Antirust Degreaser as part of its industrial cleaning and maintenance product range.

Why Metal Surfaces Need Degreasing Before Maintenance

Metal equipment can accumulate contaminants such as:

• Lubricating oil
• Heavy grease
• Hydraulic oil
• Petroleum residues
• Industrial dirt
• Dust mixed with oil

These contaminants can make equipment difficult to inspect and maintain.

In some maintenance processes, surfaces may also need to be cleaned before further treatment, coating or repair.

A suitable degreasing process can help remove oily contamination from the surface and make the equipment easier to inspect.

How Does an Antirust Degreaser Work?

The exact working mechanism depends on the formulation of the specific product.

Generally, an antirust degreaser is selected where the cleaning process involves removing oil and grease while considering the protection of metal surfaces against rust or corrosion.

The cleaning process may involve:

1. Loosening Oil and Grease

The degreasing components help break down or loosen oily contaminants from the surface.

2. Allowing Contamination to Be Removed

Depending on the product and application method, loosened grease and dirt may then be removed through:

• Wiping
• Brushing
• Rinsing
• Other recommended cleaning methods

3. Supporting Metal Surface Protection

The antirust element is intended to support applications where protection against rust or corrosion is an important consideration after or during cleaning.

Important: The exact corrosion-protection performance, application method and compatibility should always be confirmed from the specific product's technical datasheet or product instructions.

Antirust Degreaser vs Regular Degreaser

A regular degreaser is primarily selected for removing oil, grease and oily contamination.

An antirust degreaser is selected for applications where the cleaning requirement is combined with the need to consider metal surface protection.

The exact performance will depend on the specific product formulation.

Common Uses of Antirust Degreasers

1. Industrial Equipment Maintenance

Industrial machinery and equipment may accumulate grease and oil during normal operation.

An antirust degreaser may be considered where maintenance teams need to clean oily surfaces while also considering the condition of exposed metal components.

Typical equipment may include:

• Industrial machinery
• Mechanical equipment
• Metal housings
• Workshop equipment
• Maintenance tools

2. Cleaning Metal Components

Metal components may require degreasing before inspection, maintenance or further treatment.

An antirust degreaser may be useful for cleaning applications involving suitable:

• Steel components
• Metal parts
• Mechanical assemblies
• Equipment surfaces

Always confirm product compatibility with the specific metal before use.

3. Surface Preparation Before Maintenance

Oil and grease can interfere with maintenance and inspection activities.

Before carrying out certain processes, a surface may need to be cleaned to remove contaminants.

This can include preparation before:

• Equipment inspection
• Mechanical repairs
• Maintenance work
• Further surface treatment

The correct cleaning and protection process should depend on the requirements of the next maintenance stage.

4. Workshop and Industrial Maintenance

Antirust degreasers can also be considered for workshop environments where equipment is regularly exposed to:

• Oil
• Grease
• Dirt
• Moisture

A planned cleaning and maintenance routine can help keep equipment surfaces accessible and easier to inspect.

How to Use an Antirust Degreaser

The correct application method depends on the specific product.

Before using an antirust degreaser:

Step 1: Check the Product Instructions

Always review:

• Product label
• Technical datasheet
• Safety Data Sheet (SDS)
• Recommended application instructions

Step 2: Identify the Surface

Determine the material you are cleaning.

This may include:

• Steel
• Other metals
• Painted surfaces
• Mechanical components

Not every cleaning chemical is suitable for every surface.

Step 3: Remove Excess Grease

For heavy contamination, remove loose or excessive grease using appropriate materials before applying the cleaning product.

Depending on the surface, this may involve:

• Rags
• Brushes
• Suitable absorbent materials

Step 4: Apply the Product According to Instructions

Apply the antirust degreaser only according to the manufacturer's recommended method.

Do not assume that all antirust degreasers should be:

• Sprayed
• Diluted
• Brushed
• Rinsed

Application methods vary by formulation.

Step 5: Remove Loosened Contamination

Remove oil and grease according to the product instructions.

Depending on the product, this may involve:

• Wiping
• Rinsing
• Brushing
• Other approved cleaning methods

Step 6: Inspect the Metal Surface

After cleaning, inspect the equipment to ensure that:

• Oil and grease have been removed.
• The surface is suitable for the next maintenance process.
• There is no visible contamination remaining.
• Further treatment is carried out where required.

Antirust Degreaser vs Rust Remover

These products serve different purposes.

Antirust Degreaser

An antirust degreaser is used for cleaning applications involving oil and grease while considering rust protection.

Rust Remover

A rust remover is designed specifically for dealing with existing rust on suitable surfaces.

The EPOCHEM range also includes EPOCHEM 430 Rust Remover and EPOCHEM 420 Rust Guard, which are separate products from EPOCHEM 501 Antirust Degreaser.

This distinction is important:

A product intended to help prevent rust is not necessarily designed to remove heavy existing rust.

If significant rust is already present, a dedicated rust-removal process may be required.

Antirust Degreaser vs Rust Guard

A rust guard and an antirust degreaser can also serve different functions.

Antirust Degreaser

Focuses on cleaning oily or greasy surfaces while supporting applications where rust protection is a consideration.

Rust Guard

Typically focuses more directly on protecting suitable metal surfaces from rust or corrosion.

The EPOCHEM product range lists EPOCHEM 420 Rust Guard separately from EPOCHEM 501 Antirust Degreaser, indicating that they are different products intended for different maintenance needs.

For equipment that requires both cleaning and longer-term protection, the appropriate maintenance process should be determined based on the equipment, environment and product instructions.

When Should You Use an Antirust Degreaser?

Consider an antirust degreaser when your maintenance application involves:

• Oil or grease on metal equipment
• Cleaning before maintenance
• Cleaning mechanical components
• Preparing suitable surfaces for further work
• Equipment exposed to conditions where corrosion is a concern

The right product should always be selected based on:

• Type of contamination
• Surface material
• Cleaning method
• Environmental conditions
• Required level of corrosion protection

Choosing the Right Degreaser for Metal Equipment

Before selecting a degreaser, ask the following questions:

What Are You Removing?

Are you dealing with:

• Light oil?
• Heavy grease?
• Hydraulic fluid?
• Petroleum residues?
• Existing rust?

Different problems may require different products.

What Type of Metal Are You Cleaning?

The surface may be:

• Mild steel
• Stainless steel
• Aluminium
• Painted metal

Always check compatibility before applying industrial chemicals.

Do You Need Rust Removal or Rust Protection?

This is an important distinction.

If you are dealing with:

Existing rust → Consider an appropriate rust remover.

Oil and grease + rust prevention concerns → Consider an antirust degreaser.

Longer-term surface protection → Consider an appropriate rust guard or corrosion inhibitor.

Antirust Degreaser for Industrial Equipment Maintenance

Industrial equipment maintenance often involves several stages.

For example:

Stage 1: Remove Oil and Grease

Use an appropriate degreasing product.

Stage 2: Inspect the Surface

Check for:

• Rust
• Damage
• Corrosion
• Leaks
• Worn components

Stage 3: Treat Existing Rust

If rust is present, use an appropriate rust-removal method where suitable.

Stage 4: Apply Protection Where Required

Depending on the maintenance requirements, consider:

• Rust guards
• Corrosion inhibitors
• Protective coatings

This approach helps maintenance teams avoid using one product for multiple problems where specialised products may be more appropriate.

Common Mistakes to Avoid

Using an Antirust Degreaser as a Rust Remover
