What water is used for rinsing between colors?

• A. Disposable cups, discarded after client.
• B. Reusable bottles refilled between clients.
• C. Tap water in glass bottles.
• D. Distilled water kept in a box

Answer: (A)

Using fresh, single-use water containers for rinsing between colors is a key infection-control practice. Disposable cups that are discarded after each client ensure that the water and container you’re rinsing with aren’t tainted by pigments, blood, or bacteria from the previous client. This minimizes the risk of cross-contamination and keeps the rinse water clean for every color change.

Other options fall short because reusable bottles refilled between clients can accumulate ink residues and microorganisms, tap water stored in glass bottles can become contaminated and reused, and distilled water kept in a box isn’t a reliable way to guarantee one-use-per-client hygiene. The disposable-cup approach provides a simple, effective way to maintain a clean rinse for each client.
