You cannot be green and you cannot assure the safety of the worker based on selecting a supposedly safe and/or green cleaning agent. You have to consider the process, the way the cleaning agent is used. Concentration, temperature, time, mechanical force, all contribute to the overall safety and environmental preferability of the process. Consider rinse steps, water usage, product rework rate. A supposedly green cleaning process that puts a high proportion of your product in the landfill may not be green for your purposes.
