Trichloroethylene (TCE) has long been used as an industrial cleaning and degreasing solvent due to its strong cleaning power and effectiveness in vapor degreasing applications. However, in December 2024, the EPA finalized a TSCA rule that bans all consumer uses of TCE and phases out most industrial and commercial uses, allowing only limited exemptions for certain critical applications.
This regulatory shift has prompted many manufacturers to transition to safer TCE alternatives to not only meet regulatory compliance, but to improve worker safety and their environmental impact.
In this guide, we’ll explore why companies are replacing TCE, what to look for in a TCE alternative, and how to choose the right cleaning solution for your application.
Key Takeaways
- TCE has historically been used for industrial degreasing, precision cleaning, and vapor degreasing applications.
- Many organizations are transitioning away from TCE due to health, environmental, and regulatory concerns.
- Several alternatives are available that can provide effective cleaning performance while reducing risk.
- Material compatibility, cleaning effectiveness, worker safety, and compliance requirements should all be considered when selecting a replacement.
- Successfully choosing TCE alternatives requires evaluating both the cleaning chemistry and the cleaning process.
What Is TCE?
Trichloroethylene (TCE) is a chlorinated solvent commonly used for cleaning and degreasing metal parts and components. For decades, it has been widely used in industries such as aerospace, automotive, electronics, medical device manufacturing, and general industrial manufacturing.
TCE has been particularly popular in vapor degreasing operations because of its ability to dissolve oils, greases, machining fluids, and other difficult contaminants. However, concerns about its health and environmental profile have led many companies to evaluate safer alternatives.
Why Companies Are Switching to TCE Alternatives
Organizations across a variety of industries are moving away from TCE for several important reasons.
Worker Health Concerns
TCE has been associated with significant health risks and has been classified as a carcinogenic substance. Exposure can occur through inhalation, skin contact, or prolonged workplace exposure, making worker safety a major consideration.
Environmental Concerns
In addition to health risks, TCE has been identified as a hazardous air pollutant and has been linked to broader environmental concerns. Many companies are actively seeking cleaning solutions that help reduce their environmental footprint.
Regulatory Pressure
As regulations continue to evolve, organizations must carefully evaluate whether their cleaning processes align with current and future compliance requirements. Replacing TCE can help simplify compliance efforts and reduce regulatory risk.
Operational Challenges
TCE can present operational challenges related to chemical stability, solvent management, waste generation, and energy consumption. In many cases, modern alternatives can help improve process efficiency while reducing operating costs.
Common Applications That Traditionally Used TCE
TCE has been used across a wide range of industrial cleaning processes, including:
Vapor Degreasing
One of the most common uses of TCE has been vapor degreasing, where solvent vapors remove oils, greases, and other contaminants from metal parts.
Precision Cleaning
Precision cleaning applications often require the removal of microscopic contaminants that can affect product performance and reliability.
Aerospace Cleaning
Aerospace manufacturers frequently use precision cleaning processes to meet strict cleanliness specifications for critical components.
Electronics Cleaning
Electronic assemblies may require residue-free cleaning to remove fluxes, oils, and other manufacturing contaminants.
Medical Device Manufacturing
Medical device manufacturers often rely on highly controlled cleaning processes to meet quality and cleanliness requirements.
Metal Parts Cleaning
TCE has traditionally been used to clean machined, stamped, cast, and fabricated metal components prior to assembly or finishing operations.
What to Look for in a TCE Alternative
Not all TCE replacements offer the same performance characteristics. When evaluating alternatives, consider the following factors:
- Cleaning Effectiveness: The replacement should effectively remove the contaminants present in your process.
- Material Compatibility: Ensure the cleaner is safe for metals, plastics, elastomers, and other materials used in your application.
- Worker Safety: Evaluate exposure limits, toxicity profiles, and handling requirements.
- Regulatory Compliance: Verify that the product supports current and anticipated compliance requirements.
- Energy Efficiency: Some alternatives may require less energy during cleaning operations.
- Waste Reduction: Consider how the replacement impacts waste generation and disposal costs.
- Equipment Compatibility: Determine whether the cleaner can be used in existing cleaning systems and vapor degreasers.
Types of TCE Alternatives
Several categories of cleaning solutions can be used as TCE alternatives, depending on the application.
Modified Alcohol Cleaners
Modified alcohol cleaners offer strong cleaning performance and are commonly used in precision cleaning applications requiring the removal of complex contaminants.
Fluorinated Solvents
Fluorinated solvents are often selected for applications that require high-performance cleaning, low residue levels, and compatibility with sensitive components.
Aqueous Cleaners
Aqueous cleaners utilize water-based formulations to remove oils, greases, and particulate contamination while supporting worker safety and sustainability goals.
Hybrid Solvent Systems
Hybrid cleaning systems combine different technologies to balance cleaning performance, material compatibility, and operational efficiency.
Low-VOC Industrial Degreasers
Low-VOC degreasers are designed to reduce emissions while providing effective cleaning performance for a variety of industrial applications.
Benefits of Switching from TCE to TCE Alternatives
Replacing TCE can provide a number of advantages:
- Improved worker safety
- Reduced environmental impact
- Easier regulatory compliance
- Lower waste disposal requirements
- Potential reductions in operating costs
- Improved sustainability initiatives
- Enhanced process efficiency
For many organizations, these benefits extend beyond compliance and contribute to long-term operational improvements.
Challenges When Replacing TCE
While switching from TCE can provide significant benefits, it’s important to carefully evaluate the transition process.
Common challenges may include:
- Validating cleaning performance
- Assessing compatibility with existing equipment
- Evaluating drying requirements
- Meeting cleanliness specifications
- Training personnel on new procedures
- Updating process documentation
Conducting testing before implementation can help ensure a smooth and successful transition.
