Distinguished by their hard, smooth finish and glossy appearance, porcelain enamel sinks are composed of fused powdered glass. Enamel sinks come in many hues to complement any bathroom or kitchen decor Like all sink materials, enamel accumulates soap scum, dirt and stains which dull its lustre. Consistent cleaning of enamel is required to prevent abrasive debris fragments from scratching or wearing its finish.
Squirt 1/2 tsp of liquid dish detergent in a bucket containing 1 gallon of warm water. Saturate a nonabrasive sponge in the sudsy warm water.
Wipe the soapy, wet sponge over the enamel finish to loosen grime and stains. Rinse the sponge as it becomes dirty to prevent spreading dirt around.
Soak a soft rag with warm water. Wipe the enamel with the soaked rag to rinse off soap and grime.
Examine the enamel finish for stuck-on dirt stains and soap scum. If stubborn filth persists, mix 1/4-cup of warm water and 1/2-cup of baking soda in a bowl.
Coat the dirt stains and soap scum with the homemade paste using a spatula. Let the paste fully dry.
Soak a fresh rag with warm water. Wipe the hardened paste off the enamel sink using the soaked rag. Thoroughly rinse the enamel finish.
Dry the enamel finish with a soft towel.
Substitute a commercial all-purpose cleaning spray for the detergent solution. Substitute powdered water softener for baking soda.
Scouring powders can scratch enamel sinks. Acid-based cleaners can disintegrate enamel finishes over time.
