  • Remove metallic cans from the sink and bathtub. Metal cans like those that contain air fresheners and shaving creams have metal rings at the bottom. These rings rust and end up causing rust stains on surfaces. Instead, store these cans in a cabinet.

  • After using a sink or tub, wipe it down. That way, you will have removed iron residue and standing water.

  • Ventilate bathrooms. Ventilation reduces moisture and this in turn decreases the likelihood of water pooling in the sink or tub.
