Hi all, I have a friend with a domestic cleaning business who has just invested a fair amount of money in a steam cleaner. She is planning on using it mainly on hard surface e.g. tiles, worktops, sinks etc. She is wondering what degergents are out there for pre spraying. Obviously a pre spray is required that is safe to use in food preperation areas as well as bathrooms and tiles / grout etc. I personally haven`t a clue as this is way out of my area of expertees !!!!! Any info on products and suppliers would be more than welcome !!!! Best regards, Geoff
