Cleaning, disinfection and sterilization are important phases for the hygiene of medical instruments. Instruments must be disinfected with appropriate tools and then maintained with appropriate solutions. Let's not forget that washing the instruments in machines saves money and extends the life of the instruments, and the quality of the water used is very important for disinfection. Tools must be thoroughly lubricated after cleaning. The oils used must be suitable for these processes and must be water soluble.
