Alkaline pre-cleaner for boat hulls and decks
The highly concentrated, phosphate-free Hull PreCleaner alkaline for pre-washing the boat deck and hull. The combination of high-quality complexing agents and special surfactants quickly dissolves even stubborn deposits such as bird and duck droppings, environmental and weather-related soiling and is therefore ideal for alkaline pre-cleaning. Suitable for gelcoat and boat paint surfaces as well as teak replacement coverings and PVC.
Recommendations for Use
Dilute the pre-cleaner 1:20 to 1:60 with water, depending on the degree of soiling; apply to the surface using a DPZ or washing sponge and leave to work for a maximum of 5 minutes. If necessary, rework with the Interior Scrubber. Then wash off thoroughly with water and a sponge. Avoid sensitive surfaces such as galvanized steel and aluminium surfaces or real wood. After thorough cleaning, polish and seal the surface to protect it from rapid resoiling.
Check for material compatibility before use. Do not use on real wood. Only use on washable surfaces. Do not use on hot surfaces. Do not allow to dry.
