I heard to use ammonia to start, of any kind(waste)ect... I wanted to try pure ammonia from the bottle but read that u shouldnt use ammonia with surfactant in it, but I havent found a bottle of ammonia without surfactant in it? I guess its sum kind of soap or cleaner thats bad when useing how i or we want to. Is this true, and if so where the He** does one find it?
