Hi Paul
Within the environments you have described we usually supply one product which is suitable for grease, fats and general cleaning on flooring (all types), duct work, canopies, food prep surfaces, ovens ets. I would be glad to talk with you about the use of our products and how they work as they are not chemicals or solvents, the technique is called bioremediation, sounds complecated and expensive but its not. You can contact me through my office, i'm there now (sad man), 08450 636666.
regards
