Final answer:
Dry brushing is an ineffective method for cleaning instruments and is not recommended by OSHA because it fails to eliminate all microorganisms and may spread contaminants.
Step-by-step explanation:
Dry brushing is an ineffective means of cleaning an instrument and not recommended by OSHA. Effective instrument sterilization is critical for preventing the transmission of infections in healthcare settings. Dry brushing may remove some debris but it does not eliminate all microorganisms, which is necessary to ensure the cleanliness and safety of medical instruments. Furthermore, dry brushing can generate aerosols that may spread contaminants. According to OSHA and the Centers for Disease Control and Prevention (CDC), the best practice includes a thorough wash with water and the use of a chemical disinfectant or sterilizing through methods such as autoclaving, which employs high-pressure saturated steam to achieve sterilization. This ensures that all potential pathogens are destroyed before an instrument is used again on a patient.
