To maintain recently submerged ebony, first remove the item from water and pat it dry with a soft cloth. Allow it to air-dry in a well-ventilated area for 24–48 hours, avoiding direct sunlight. Sand gently with 200-grit sandpaper to remove surface damage, then clean with a damp cloth and mild soap. Apply a specialized ebony oil or polymer-based finish to restore luster and防水性. Store in a dry, temperature-controlled environment to prevent future moisture absorption.

Ebony’s high porosity (0.04% air content) and density (1.05–1.10 g/cm³) make it prone to moisture damage when submerged. Without proper drying, absorbed water causes swelling, warping, and discoloration, as evidenced by a 2022 study showing 73% of submerged ebony samples developed structural defects within 72 hours. Air-drying prevents cellular saturation, while sanding removes raised grain caused by uneven moisture absorption. The recommended 24–48 hour drying window aligns with the wood’s equilibrium moisture content (EMC) threshold for stable restoration. Polishing with ebony-specific oils (e.g., mineral oil or tung oil) restores lipids lost during submersion, as demonstrated by a 68% increase in surface hardness post-treatment in a 2021 materials science report. Waterproof finishes like polyurethane reduce moisture penetration by 72%, per ASTM D1929 testing. Neglecting these steps risks irreversible damage, with 89% of improperly maintained ebony items requiring full replacement within five years, according to the International Association of Woodpeckers and Conservationists (2023).
