Jeff,
I was there about 3 years. I was the internal operations guy, not involved in formulations but responsible for formulating/mixing, bottling, stocking, logistics, hardware manufacturing, and purchasing for the Bridgewater companies. I have a supply chain/manufacturing/operations management background (MBA, etc.). I have a lot of general manufacturing experience, but whatever I know about the formulation of cleaning chemicals I picked up on the job. I'm not nor have I ever been a professional cleaner but I do have a little porty and clean my own 15-year old builders-special carpets. I gotta break down and replace those POS carpets soon!
I went back to the aerospace/defense industry, and don't know why I'm still peering in on the industry, checking the Interlink and Jon-Don websites for new products and services, etc. I guess it'll get out of my bloodstream someday...maybe it's just PTFE poisoning from being around too many protectants!
