A wet sanitizer should contain a disinfectant solution instead of an antiseptic solution, 30% alcohol or 2% formalin. This is because a disinfectant solution is specifically designed to kill harmful bacteria and viruses on surfaces, while an antiseptic solution is primarily used for cleansing and disinfecting wounds on living tissue. 30% alcohol and 2% formalin are both too strong and can be harmful to use as a wet sanitizer.
