1. Pre-wet the surface (do not saturate) with water before applying Heritage Restorer.
2. For best results, apply Heritage Restorer with a low-pressure sprayer (brushing is not necessary).
3. For the lighter soils, a single application with a 10-minute dwell time will remove many of the stains.
4. For deeper soils or very porous surface, a double application with 10-minute dwell for the first application; then reapply and allow up to 1 hour total dwell time will provide the best results. Do not rinse between applications.
