Get The Right Cleaning Solvent Alternative

On December 20, 2019, the EPA finalized the designation of 20 chemical substances as “high priority for risk evaluation” under the Toxic Substance Controls Act (TSCA). Included are Methylene chloride, Perchloroethylene (PCE/ PERC), n-Propyl Bromide (NPB) – which the EPA refers to as 1-bromopropane – and Trichlorethylene (TCE).

Today, these chemicals are moving through the process required by TSCA to evaluate any unreasonable risks they may present to human health or the environment.  The next step is risk management of these existing chemicals in order of priority. There are several actions EPA could take to address the unreasonable risk, including regulations prohibiting or limiting the manufacture, processing, distribution, commercial use, or disposal of the chemical substance, as applicable.

Hubbard-Hall has been helping manufacturers tackle solvent issues head-on for nearly 70 years. We offer both aqueous and solvent chemistries. So, whether you want a lower-impact solvent or need get out of solvents altogether, we have the right cleaner for you. We even offer an on-site cleaning consult to help you find the right solvent alternative.

Cleaning is a Process

Although chlorinated/fluorinated/brominated solvents have advantages in precision cleaning, there are other methods for removing soils from the surface of metal. Cleaning is considered a process because it is not just about the chemistry – good cleaning depends on several factors:

  • Metal type
  • Soil type
  • Parts geometry
  • Available footprint
  • Application cleanliness requirements
  • Throughput requirements
  • Energy demands
  • EHS and regulatory
  • Waste handling
  • Cost

Next-Gen Solvents


Solvent cleaning or degreasing is a process in which a solvent chemical is used to dissolve organic contaminants on the workpiece.

Environmentally friendly solvents such as modified alcohols (Dowclene™ and Dualene™) can be used in a vacuum degreaser for cost savings, safety, and efficacy. This type of solvent cleaning will require capital investment, including the purchase of a vacuum degreaser.

Tergo is a precision cleaning fluid that is a non-flammable, thermally and hydrolytically stable cleaner that can be dropped into an open top vapor degreaser.

Aqueous Cleaners


Aqueous cleaning is a water-based process that utilizes chemical additives and rinsing to remove contaminants.

We offer 70+ water-based chemistries for any soil, substrate or cleaning process.  With a transition to aqueous cleaning, you should consider how this will impact your process with the use of heat, multiple tanks, drying time and increased footprint.

This webinar hosted by TURI (Toxic Use Reduction Institute) showcases how CD Aero was able to find annual cost savings and productivity improvements when switching from solvent to aqueous cleaning with the help of our experts.

Solvent Risk Mitigation by Regulatory Bodies

In addition, different regulating bodies have different opinions on risk mitigation. Below is an example on how OSHA, ACGIH and the EPA differ in acceptable exposure limits for TCE/PEC/nPB/MEC.
SolventOSHA (PEL) ppmACGIH (TLV) ppmEPA (ECEL) ppm

Ppm – parts per million
Tlv – threshold limit value
Pel – permissible expose limit
Ecel – existing chemical exposure limit (8 hour)
Stel – short term exposure limit (15 minutes)
