Please read the following instructions for conserving a damaged nineteenth-century leather book binding:

To conserve a nineteenth-century leather-bound book, follow these steps:
First, gently brush away surface dust from the cover using a soft-bristled brush. Before applying any consolidant, ensure that you have cleaned the red rot areas with a dry sponge to remove loose fibers. Immediately after cleaning, apply a thin layer of Klucel G (a hydroxypropyl cellulose consolidant) to the damaged leather and let it dry completely for at least two hours. Once the consolidant is fully dry, and only then, apply a microcrystalline wax polish to protect the leather from moisture. Ensure that you buff the surface with a microfiber cloth only after the wax has set for ten minutes. Finally, store the book in a temperature-controlled environment.

Based on the guide, which of the following steps must be completed immediately before the microcrystalline wax polish is applied?

Protocol for Accessing the Advanced Biomaterials Laboratory:
All researchers must obtain level-3 clearance prior to entering the facility. While it is strongly suggested that personnel wear double-layered nitrile gloves, standard latex gloves are mandatory at all times. In the event of a minor chemical spill, researchers should immediately notify the floor supervisor, although filing a formal incident report is only required if the spill exceeds 50 milliliters. For spills under this threshold, documenting the event in the shift log is highly recommended to maintain protocol transparency. Furthermore, before leaving the laboratory, it is incumbent upon all staff to sanitize their workstations, and they are encouraged to run the automated self-cleaning cycle on the fume hoods if the daily usage exceeded four hours.

Read the following instructions for preparing a natural indigo dye vat:

To prepare a natural indigo dye vat, follow these steps:
Initially, heat the water in the vat to exactly $50^\circ\text{C}$ to ensure the indigo powder disperses evenly. Previously, the indigo must be thoroughly ground into a fine paste with a small quantity of warm water. Prior to introducing the reducing agent, dissolve the alkaline agent (hydrated lime) and stir the solution gently in a single direction to avoid incorporating oxygen. Subsequently, once the pH stabilizes at $11$, add the sodium hydrosulfite. Let the vat rest undisturbed for $45$ minutes. Finally, once the liquid beneath the surface bronze skin turns a clear amber-yellow, the first fabric immersion can begin.

Based on the instructions, which action must be performed immediately before adding the sodium hydrosulfite?
