PWR-4 Solvent Cleaners




The performance you need at the price you want!

PWR-4™ solvent cleaners are ideal where a safer, non-flammable, and cost effective aerosol cleaner is required. This innovative cleaner is much safer than the four most common industrial solvents: TCE, nPB, Perc and  Methylene Chloride and quickly blasts off oils, greases, fluxes, silicones, dirt and grime.

  • Non-flammable
  • Much safer than most common industrial solvents — TCE, nPB, Perc & Methylene Chloride
  • Powerful cleaner — Ideal for degreasing and contact cleaning
  • Available in aerosol or bulk for vapor-degreasing, ultra-sonic and bucket cleaning
  • Rapid evaporation


  • Heavy-duty degreasing
  • Contact cleaning
  • Flux removal
  • Cleaning: relays and switches, transformers, electric motors and generators, electronic controllers, pneumatic and hydraulic systems, circuit breakers.

n-Propyl Bromide (nPB), Trichloroethylene (TCE), and Perchloroethylene (Perc) are three examples of harmful chemicals that are commonly used in aerosol cleaners in industrial applications. These chemicals are commonly used as cleaning solvents because they are non-flammable, have high solvency, and are relatively inexpensive.

Because of safety concerns, these solvents are under close scrutiny by OSHA, EPA, and local agencies. For example, The American Conference of Governmental Industrial Hygienists (ACGIH) recommends a 10 ppm time-weighted average threshold limit of nPB, but has proposed a lower 0.1 ppm (ACGIH 2013). That’s because nPB is a suspected human carcinogen, and has shown to negative impact neurological and reproductive functioning.

Techspray offers effective replacements for these toxic solvents. PWR-4 High Performance Solvents provides all the cleaning power of nPB and other industrial solvents, but without the health risks. For more information, read “Toxic Chemicals Used for Industrial Cleaning” white paper.
