When baking a cake how can you remove dust from icing?

To remove dust from icing on a cake, gently use a clean, dry brush or a soft pastry brush to sweep away any particles. Alternatively, you can lightly blow on the surface to dislodge any dust. For best results, ensure that the cake is covered or stored properly before icing to minimize dust accumulation. If dust persists, consider adding a light layer of fresh icing to cover it up.
