If you would pay attention to his posts, he sells industrial. He also has a patent on a commercial product using chlorine dioxide. He has made several bottles of 5% solution for mouthwash, but has not tried to sell it. He offered it to you free of charge, but you are so intent on attacking him, you don't see what he is saying. He has a patent on a commercial product using chlorine dioxide that I'm sure that you will hear about in the future, but it isn't for sale to any of you. It is commercial. He has been concerned about the amount of product that you are ingesting, because he has worked with it for years, and knows what it can do. All of you think that he is trying to stop you because he is mean, but he is trying to stop the shipping of 28% solution because it is dangerous to those handling it during the shipping. The paranoia on this board is amazing! If someone disagrees with anything that you are doing, they are automatically out to get you. Bruce is trying to help you, and in the process has been attacked. He reacted like anybody would, he got angry. Once again, HE ISN'T TRYING TO SELL YOU ANYTHING!!
