Things You'll Need
Bathroom disinfectant cleaner
Plastic spray bottle
Mold killer and inhibitor spray
Mold is present in nearly all homes and is commonly found growing in bathrooms where warm and humid conditions encourage the spores to germinate. A bathroom sink is an ideal surface for mold growth due to its always-moist nature. Mold not only looks unappealing and disfigures your sink's appearance; but it can also pose a respiratory health hazard. Kill mold and remove visible mold growth in your sink to restore your sink's appearance and protect your health.
Scrub the sink with a sponge and standard disinfecting bathroom cleaner. This option is best for small mold spots and mold growing on a smooth surface such as porcelain or fiberglass. Alternatively, pour boiling water on the mold instead of using bathroom cleaner, which is ideal for homeowners who prefer to not use chemicals.
Mix a homemade bleach solution. This method is best for heavy mold growth, stained sinks or mold on a non-smooth sink surface that is difficult to scrub. Pour equal parts of bleach and water into a spray bottle. Mist the mold growth in your bathroom sink.
Allow the bleach solution to soak into the mold for 15 minutes. Wipe away with a sponge. Rinse the area thoroughly to remove all remnants of the bleach.
Spray the mold with a mold killer spray and inhibitor. This method is best for those who don't want to mix their own spray as well as bathrooms that have recurring problems with mold infestations. Follow the product manufacturer's usage guidelines as toxicity varies widely by product.
Prevent mold from growing back after killing it. Run a dehumidifier in your bathroom, which dries out the air and kills mold spores, or open any available windows to increase air flow. Stagnant, moist air is a common problem in bathrooms and a major factor in mold growth in your bathroom sink.
