The specific answer depends on what your specific application includes.
#1: What are you removing? (solder paste, adhesives)
#2: What are you cleaning? (stencils, screens, misprints, pallets)
#3: What type of machine are you using? (Spray-in air, ultrasonic, heated / unheated)
A general answer� There are numerous brands of stencil cleaning chemicals available.

All of the chemicals listed above work well. When choosing a specific brand, consider the following:
#1 Cost How much per gallon / liter? Is it sold as a concentrate or ready-mix? What is its loading capacity (how long will a batch last)?
#2 Safety Is the solution flammable or non-flammable. What type of machine is it designed for (some chemicals are designed for ultrasonic but not spray-in-air).
#3: Environmental Is the chemical environmentally safe and legal? Is it VOC free or VOC compliant? Can it be discharged?
