When diluting a disinfectant, it is important to add the disinfectant to the water instead of adding the water to the disinfectant. This is to prevent foaming, as adding water to a concentrated disinfectant can cause excess bubbling and foam to form. Similarly, adding soap to water instead of water to soap can also create foaming. Therefore, the correct approach is to always add the concentrated solution to the water when diluting. This will allow for a smooth and effective dilution process.
