Some form of soap is now a standard feature of any bathroom. Using soaps can help prevent cross-infection. Their use is especially important in public bathrooms, where hundreds of people use them every day. In addition to their cleansing effect, soaps remove most of the various bacteria, but correct use and the quality of the soap chosen are important. General liquid, foam and spray soaps are suitable for daily use, but it is recommended to use soaps that have been tested for antibacterial effect or have a disinfectant effect in busier places. If a sick person enters the bathroom and does not wash their hands, or does not wash them properly, they can very easily infect a healthy person even if they have cleaned their hands properly. Dispenser systems now allow for extremely economical use, and thanks to their locking system, theft of liquid soap and the dispenser can also be prevented.
