Disinfect implements with fine cutting edges with?

  1. Soap and water

  2. 70 percent ethyl alcohol

  3. 99 percent isopropyl alcohol

  4. Disinfectant spray

The correct answer is: 99 percent isopropyl alcohol

It is important to disinfect tools with fine cutting edges in order to reduce the risk of infection. Out of the given options, 99 percent isopropyl alcohol is the most effective choice for this purpose. Option A, soap and water, may not completely disinfect the tools and can leave residue on the blades which may cause irritation or contamination. Option B, 70 percent ethyl alcohol, is not as effective as the 99 percent isopropyl alcohol because the higher concentration allows for better penetration and kills a wider range of microbes. Option D, disinfectant spray, may contain chemicals that could be harmful to both you and the tools. Furthermore, it is not specifically designed for disinfecting tools and may not be as effective as the recommended option of 99 percent isopropyl alcohol.
