Removing rust converter from a zinc outdoor table requires careful steps to avoid damaging the metal. Start by wiping the surface with a damp cloth to remove loose residue. For stubborn spots, use a mild dish soap mixed with warm water and a soft-bristle brush to gently scrub the affected areas. Rinse thoroughly with clean water and dry with a microfiber cloth. If traces remain, apply a mixture of white vinegar and water (1:1 ratio) with a sponge, then rinse and dry immediately. Avoid abrasive tools or harsh chemicals, as they can scratch or corrode the zinc. Regular maintenance, like applying a protective wax, can prevent future rust buildup.
