What items cannot be used more than once, either because these cannot be cleaned of all visible residue (such as pumice stones for pedicures), or because cleaning and disinfecting damages them.

What items cannot be used more than once, either because these cannot be cleaned of all visible residue (such as pumice stones for pedicures), or because cleaning and disinfecting damages them.

• A. Multi-use items
• B. Non-porous items
• C. Porous items
• D. Single-use disposable items

Answer: (D)

Items that cannot be reused are those designed to be disposed after a single client because cleaning cannot guarantee all residue is removed or because the cleaning/disinfecting process would damage the item. Pumice stones used in pedicures, with their rough, porous surfaces, can trap microscopic debris and microbes that are very hard to remove completely through cleaning, making reuse unsafe. Some materials also degrade or lose effectiveness when exposed to sanitizers, so reusing them would pose a contamination risk. In contrast, items that are non-porous or intended for multi-use are chosen because they can be thoroughly cleaned and disinfected between clients, reducing the risk of cross-contamination. Porous items, while not always reusable, are often treated as disposable since they’re difficult to sanitize effectively. So, items meant for one-time use and disposal are the single-use disposable items.
