Preparing Your Surfaces
Test this product first on a small, hidden area to determine its effectiveness. Before you begin your wood brightening project, protect your shrubs and glass surfaces by wetting them down with water and covering them in plastic. Hose off your glass frequently, too prevent streaking, and hose off your shrubs when the job is done.
Apply liberally to problem surfaces. Do not apply to hot surfaces. To avoid a non-uniform appearance on vertical surfaces start at the bottom, doing a small section at a time, then continue to the top, making sure to rinse thoroughly. Let set for 15-20 minutes. Stubborn areas may require scrubbing with a stiff bristle brush. If surface begins to dry quickly, lightly mist with water.
Important: Allow cleaned surface to dry completely before staining or painting.
