Regular cleaning keeps your porcelain enamel sink white and stain-free. Enamel sinks consist of a metal shell that is coated with a hard porcelain layer. Coffee can leave a brown, discoloured ring around the bottom of the sink. Splashes from pouring out cups or the coffee pot can also leave small spots all over the sink's bowl. Fortunately, enamel is resistant to most permanent stains so you can quickly remove coffee stains with common household chemicals.
Rinse the sink out, washing any dirt or food particles down the drain. Sprinkle baking soda onto the moistened, coffee-stained areas inside the sink.
Scrub the stained areas with a non-abrasive sponge. Rinse and reapply the baking soda. Scrub a second time, removing as much of the stain as possible.
Combine 1 part bleach with 5 parts water. Soak a rag in the bleach solution then lay it over the stained part of the sink. Allow it to soak for 30 seconds.
Wipe the stained area with the rag, removing any remaining coffee stains. Rinse the sink immediately with clear water.
Rinse out the sink with water after every use to help prevent stains before they occur.
Do not use harsh abrasives or acidic cleaners on porcelain enamel. These cleaners permanently etch the enamel surface.
