Best way to clean aluminum boat?
Regular Cleaning – If surface is only mildly discolored, wash with soap and water, to which some mild household acid has been added; lemon juice, vinegar, or cream of tartar. Most water is slightly alkaline, so do not add ammonia, TSP or soda. Wash as needed during the season; wash at end of season. (Remember the darkening of aluminum pans when low acid or alkali foods are cooked..it blackens. When acid foods such as tomatoes are cooked in aluminum, it will become shiny.) Special Cleaning – If surface is pitted, polish with a soap-filled steel wool pot cleaner, rinse and dry. All steel wool must be removed or it will rust and stain the aluminum. Wash and dry.
