Star brite hydrochloric acid-based hull and bottom cleaner Ez-on Ez-off cleans the hull of the boat from vegetation, slime and seaweed, etc. The product is buffered, so it is safer than other acid-based boat bottom cleaning products. Suitable for fiberglass, wood and iron surfaces. Also works well in cooler washing conditions. Always finish the surface with an appropriate boat wax. 
DIRECTIONS FOR USE: Lift the boat out of the water and remove the largest growths. Allow the growths and stains to dry completely. Stains and growths above the waterline can be removed while the boat is in the water. Pour the product into an open plastic container and apply to the dry surface of the hull with a natural bristle brush. Keep the growths and stains wet and foaming with the product. Foaming is an indication that the product is removing the growths. Add product to maintain the foaming. After a few minutes of foaming, most surfaces will be clean and ready to rinse with water. For heavy growth, cleaning may require multiple applications and light scraping.
NOTE: Avoid spilling or splashing on surfaces other than those being treated. Test on a small area of ??aluminum frames before applying. Cover trailer with plastic sheeting to prevent staining or damage to metal surfaces. Rinse spills thoroughly immediately. Product will discolor some primers. Avoid contact with fabrics or carpets. Use caution when transporting to prevent splashing. DO NOT MIX WITH OTHER CLEANERS.
