What can be used to pre-clean instruments?

1. Soap and water

2. Ultrasonic cleaner

3. High frequency energy waves

4. Chemical dip

The correct answer is: High frequency energy waves

Option A Soap and water is a common choice for cleaning instruments, but it is not typically used as a pre-cleaner. Soap and water may not effectively remove all types of debris and can leave residue on the instruments. Option B: Ultrasonic cleaners use sound waves to create small bubbles which agitate and remove debris from instruments. While they can be effective for cleaning, they are not typically used as a pre-cleaner. Option D: Chemical dips can be harsh and may not be suitable for all types of instruments. They are often used as a final step in the cleaning process, rather than a pre-cleaning method. Pre-cleaning with high frequency energy waves is a more thorough method and can help remove hard-to-reach debris before instruments go through a more intensive cleaning process. This method often uses ultrasonic waves or other energy sources to thoroughly clean and disinfect instruments. This option may not be as widely known as conventional methods, but it can be highly effective in ensuring clean and safe instruments.
