Shake bottle well prior to use. Use rubber gloves. For liquid hull cleaner, apply solution directly to the surface with a sponge or sprayer and allow it to sit for about 2 minutes. For spray gel, spray solution directly onto the surface and allow it to sit until the stain breaks up.
Rinse the treated area thoroughly with clean, fresh water. Repeat if necessary. Stubborn stains or buildup may require a second application, longer soak time, or gentle scrubbing.
For best results, use when temperature is above 50°F. Avoid contact with fabrics, anti-fouling bottom paint, and inferior quality decals, as discoloration may occur. Avoid contact with boat trailers and other unintended surfaces. Test in an inconspicuous area before full application.
