U.S. Navy Air Systems Command

Case Study Type: Precision Cleaning

Target Solvent: 1,1,1, Trichloroethane


Faced with the ban on 1,1,1 Trichloroethane and other class I ozone depletes used for cleaning activities on the Navy’s aircraft the Navy asked Inland Technology to develop a replacement solvent that would work as well for the same tasks. The alternative had to clean effectively, leave no residue, and be nonconductive. It also had to pass independent laboratory performance and material compatibility tests. 


Inland’s research scientists created a precision cleaning solvent Teksol®EP that replaced the target solvent and also acts as an alternative to brake cleaner and electrical cleaning solvents and saves considerable cost when used with Inland’s reusable aerosol sprayer the Airjet 24™.

Teksol®EP Results:

  • Teksol®EP has full engineering approval from NADEP Jacksonville as a waterless wipe solvent for prepping aircraft prior to painting, bonding, and sealant application.
  • Teksol®EP is also approved for cleaning: avionics, electrical systems, hydraulic systems, and fire control systems.


Teksol®EPhas had great success replacing N Propyl Bromide and other halogenated solvents used for cleaning electrical generators in hydro-electric dams. However, its greatest success has been as a replacement for the toxic solvents used in brake cleaners.
