Which of the following is an acceptable cleaning solution for equipment decontamination?

Distilled water is often used in decontamination processes because it is free from impurities and contaminants that can interfere with the cleaning process. Its neutral nature makes it a safe choice for rinsing equipment without introducing additional chemicals that might react with residues. Using distilled water can help flush away contaminants effectively without leaving harmful or unintended residues behind.

In contrast, ammonia and petroleum ether can introduce their own risks during the cleaning process, such as leaving chemical residues that may be harmful or cause reactions with other substances. Chlorine bleach, while effective for disinfection, can also leave residues and can be corrosive or damaging to certain types of equipment. Thus, distilled water stands out as a safe and effective option for cleaning decontamination, making it an acceptable choice for this purpose.
