Disposing of brushes is preferred to storing them for later use.

• A. Disposing of brushes
• B. Storing for later use
• C. Reusing after cleaning
• D. Donating

Answer: (A)

Sanitation and cross-contamination prevention when handling brushes used on potentially contaminated materials is the main idea. After use, brushes can hold residues, bacteria, or mold, and the bristles can become damaged or wear down. Storing them for later use risks spreading contaminants to other tools or tasks, and cleaning alone may not remove all residues or restore the brush to a safe, effective condition. Reusing after cleaning can still leave hidden residues or compromised bristles, making performance unreliable. Donating used, potentially contaminated brushes isn’t appropriate either. Disposing of the brush and replacing it with a fresh one minimizes contamination risk, maintains safety, and ensures reliable results.
