An effective disinfectant used to clean the surface of equipment?

Correct option is D

​The correct answer is (d) Iodine​

Iodine is a highly effective disinfectant commonly used for cleaning the surfaces of equipment, particularly in medical, laboratory, and food industries. Iodine-based solutions, like povidone-iodine, are widely recognized for their antimicrobial properties. They work by penetrating microbial cell walls and disrupting protein and enzyme functions, effectively killing bacteria, viruses, and fungi. Iodine is especially useful for sterilizing surfaces because it is non-corrosive when used correctly and leaves minimal residue.

Iodine's broad-spectrum antimicrobial activity makes it a reliable choice for disinfecting critical surfaces where hygiene is paramount.

Information Booster:

● Iodine is effective against bacteria, viruses, and spores, making it a broad-spectrum disinfectant.
● It is used in both liquid and vapor forms for surface disinfection.
● Iodophors, which are iodine mixed with surfactants, enhance its efficiency and reduce staining.
● Iodine is also used in antiseptic preparations for skin disinfection during surgeries.
● Proper handling is necessary as excessive use can stain surfaces or cause mild skin irritation.

Additional Knowledge:

• (Option A) Sodium metasilicate: A cleaning agent, primarily used as an industrial detergent, not a disinfectant.
• (Option B) Citric acid: Effective for descaling and cleaning but lacks broad-spectrum antimicrobial properties.
• (Option C) Tartaric acid: Commonly used in food preservation and cosmetics but not effective as a surface disinfectant.
