Water-Based Metal Degreasing: An Effective, Safe, and Sustainable Solvent Alternative
For many years, solvents such as thinner, xylene, and heptane have been commonly used to clean grease and oil from metal surfaces before painting or surface treatment. However, with increasing demands for workplace safety, environmental protection, and reduced VOC (Volatile Organic Compound) emissions, businesses are seeking more effective alternatives, including innovative Cleaners.
In this context, water-based degreasing Cleaners products are becoming a new trend due to their superior cleaning ability, reasonable cost, and high level of safety for operators.
What is Metal Degreasing?
Metal degreasing is the process of removing oil, grease, dirt, lubricants, and other contaminants from metal surfaces before painting, plating, or other surface treatments. This is a crucial step to improve paint adhesion and reduce the risk of corrosion.
Why Replace Traditional Solvent-Based Degreasing Agents?
Risks to workers’ health
Organic solvents often contain volatile compounds that can affect the respiratory system, skin, and eyes with frequent exposure. Long-term use also increases the risk of occupational diseases in the production environment.
Increased pressure to comply with environmental regulations.
Many countries and regions are tightening regulations related to VOC emissions. This makes the use of traditional solvents more expensive due to the need for investment in exhaust gas treatment systems and environmental control measures.
Cleaning efficiency is not always optimal.
Although considered a powerful degreaser, in practice, many cleaning processes using solvents simply involve wiping with a cloth. When cloths are reused multiple times, grease and dirt can be left on the surface instead of being completely removed.
As a result, residual dirt remains on the surface, reducing paint adhesion and increasing the risk of future corrosion.
Water-Based Metal Degreasing Solution as a Solvent Replacement
To meet the demands of the modern metalworking industry, AD Chemicals has developed a line of specialized water-based metal degreasing products that can completely replace traditional solvents in many industrial applications.
The products are designed to:
- Removes grease effectively.
- Leaves no residue on the surface.
- This creates an ideal clean surface for subsequent painting processes.
- Minimize risks for workers.
- Minimize environmental impact.
In particular, the product can replace solvents at a 1:1 ratio , allowing businesses to easily switch processes without affecting production efficiency.
The Outstanding Advantages of Water-Based Degreasers
1. Safer for Operators
Unlike flammable and highly pungent solvents, water-based degreasing agents improve the working environment and reduce the risk of exposure to hazardous chemicals.
2. Environmentally Friendly
Reducing solvent use means reducing VOC emissions into the environment, supporting businesses in moving towards green production and sustainable development.

As a result, businesses can easily integrate it into their existing systems without requiring significant investment.
Applications of Water-Based Metal Degreasing Agents
– Mechanical processing and metal stamping workshop
– Powder coating plant
– Steel structure production line
– Production of electrical, electronic and household appliances
– Processing of aluminum, carbon steel and galvanized steel
– Surface cleaning before painting, coating or conversion treatment
Check Cleaning Effectiveness Using Water Break Test
To assess the quality of metal surface cleaning, many manufacturers use the Water Break Test method .
What is a Water Break Test?
This is a quick and virtually non-destructive testing method to determine the presence of oil, grease, or other contaminants on surfaces.
Operating Principle
- A perfectly clean surface is hydrophilic, allowing water to spread evenly in a continuous film.
- If the water separates into droplets or a broken film appears, it indicates that the surface is still contaminated with oil or dirt.
The Water Break Test is a simple but highly effective tool for quality control before painting.

Upgrade Your Cleaning Process With MM31®
More than just cleaning, MM31® is developed to optimize the entire surface treatment process before and after mechanical machining.
After treatment with MM31®, the metal surface is not only completely clean but also develops a conversion coating that offers numerous benefits:
Increase Paint Adhesion
The conversion layer helps the paint bond better to the metal substrate, reducing peeling during use.
Enhance Corrosion Resistance
The surface is better protected against the effects of moisture and harsh environments.
Temporary Rust Prevention
MM31® has the following capabilities:
- Provides up to 48 hours of protection against brown rust on steel.
- White rust protection for galvanized steel.
- Protect the aluminum surface after treatment.
Future Trends In Metal Cleaning
The metal surface treatment industry is undergoing a significant shift in the following direction:
- Reduce VOC emissions.
- Enhance workplace safety.
- Improve production efficiency.
- Towards green production standards.
In this trend, water-based metal degreasing solutions, replacing solvents, not only help businesses meet technical requirements but also enhance their competitiveness and brand image in the market.
Water-based metal degreasing is becoming a popular alternative to solvents for many businesses due to its effective cleaning capabilities, reduced VOC emissions, and enhanced safety in production.
Businesses seeking an effective, safe, and sustainable metal surface cleaning solution should consider switching to solvent-free cleaning technology to improve product quality and meet future production requirements.
Frequently Asked Questions About Metal Degreasing
Can water-based metal degreasing chemicals completely replace solvents?
In many industrial applications, water-based degreasing agents can replace thinner, xylene, or heptane while still ensuring effective cleaning.
Does water-based degreasing affect metal surfaces?
When used correctly and at the right concentration, water-based degreasing solutions clean effectively without damaging surfaces.
What is a Water Break Test?
This is a method for testing surface cleanliness by observing how evenly water spreads across a metal.
After degreasing, is pre-treatment necessary before painting?
Yes. To increase paint adhesion and corrosion resistance, it should be combined with appropriate conversion coating technology or surface pretreatment.
Are water-based degreasers suitable for aluminum?
Yes. Many water-based degreasing products are specifically designed for aluminum and aluminum alloys, providing effective cleaning without corroding the surface.
