The effectiveness of a disinfectant can be affected by many factors, including how it is used and its concentration. If the solution is to be applied at room temperature, it needs to be diluted before use. This means that one would need to apply the solution to have an effective solution. These solutions should only be used on clean surfaces. Otherwise, they are not only ineffective but also highly toxic.
Another good solution for disinfecting is to use the solutions in the air where the bacteria are growing. This is useful as these bacteria tend to be very contagious and airborne. Therefore, it would be wise to prevent germs to other surfaces by using disinfectant solutions in air conditioning systems or the air. Such solutions should only be used as directed on the label and not to use them on other surfaces.
There are other forms of effective solutions, including alcohol and acetone solutions and some form of disinfectant based solutions. The best way to find an effective disinfectant solution would be to read labels properly and use them according to the instructions.
