Orange wood sticks cannot be disinfected after being used to push cuticles back because they are porous. This means that bacteria and other harmful microorganisms can become trapped within the material and cannot be fully removed through disinfection. Metal and plastic pushers, on the other hand, can be properly disinfected after use because they are non-porous materials that can be easily cleaned and sterilized. Similarly, cotton swabs can also be disinfected as they are made of a non-porous material. Therefore, the only option that cannot be effectively disinfected is the orange wood sticks.
