Plaza Deep Cleaning Product and Methodology

Product: Prosoco T2515 Klean & Release with T2518 Activator (PROSOCO technical Customer Care, toll-free, at 800-255-4255).

Mixing Instructions: Dilute 3 gallons water + 1 gallon Klean & Release + 1 gallon Activator, a 3/1/1 ratio. In some extremely soiled areas, the standard ratio of 3 gallons of water may require a more concentrated ratio of 2/1/1 or even 1/1/1.

Application Instructions:

1. Prewet the surface with clean water.

2. Apply the prepared solution to the surface using a roller, brush or low-pressure spray.

3. Let the cleaner dwell on the surface 5–10 minutes. While the surface is still wet, gently scrub or agitate with a nonabrasive brush or broom.

4. NOTE: Do not let the cleaner solution dry on the surface. If drying occurs, lightly wet surfaces with fresh water, then repeat the process of step 3, reapplying the prepared solution, allowing 3-5 minutes of dwell time before scrubbing a final time.

5. Rinse the surface thoroughly with approximately 300-400 psi clean water. Rinse with enough water (using a 15–45° fan spray tip) and pressure to flush spent cleaner and dissolved soiling from the granite surface and surface pores without damage.

6. Repeat at least once while the surface is still moist from the previously applied prepared solution.

Let surface dry thoroughly before inspection. Repeat entire process if dirt is still apparent.

Cleanup: Clean tools and equipment using fresh water.
