How to Remove Scratches from Ceramic Sink Without Causing Further Damage

Before starting, identify whether the scratch is surface-level or deep. Light marks are often easier to repair, while deeper ones may require specialist products.

Start with a Clean Surface

Begin by giving your sink a thorough clean with mild washing-up liquid and warm water, as outlined in our how to clean ceramic sink guide. Dry the area completely before attempting any repairs.

Baking Soda Paste for Light Scratches

For minor marks, mix bicarbonate of soda with a little water to form a paste. Apply it to the scratch, then gently rub with a soft cloth in a circular motion. This can help smooth the surface without damaging the glaze. This same method works well for lifting stains too, as shown in our how to remove tea stains from composite sink blog.

Using a Ceramic Repair Kit

Ceramic repair kits, available from most DIY stores, include filler and glaze to restore the sink’s smooth finish. Follow the instructions carefully, and always choose a colour that matches your sink.

Fine Sandpaper for Deeper Scratches and How to Remove Scratches from Ceramic Sink

For deeper marks, you can use very fine-grade sandpaper (at least 1200 grit). Wet the sandpaper and lightly buff the scratch, then apply a polish or glaze to restore the shine. Be careful not to over-sand, as this can dull the surrounding area.
