1. Keep a mold-killing spray bottle under the sink
Fill a spray bottle with a few teaspoons of tea tree oil and water and spray onto moldy areas. Keep the bottle handy and spray the same areas after you take a bath or shower to keep the mold from returning. Tea tree oil has a strong scent which will dissipate in a day or two.
Hydrogen peroxide in your spray bottle will also work and smell less pungent, but requires that you scrub away the mold after leaving it on for about 10 minutes.
2. Reduce moisture
Try not to leave wet towels on the floor or hanging on the edge of the tub near mold-friendly surfaces like caulking or grout. Keep your bathroom ventilated —open a window or run (or install) a fan during and after you take a bath or shower.
3. Seal the deal
Grout is a haven for mold — you can seal tile grout once a year with a standard grout sealer from a home improvement store to make it waterproof, and thus mold-proof.
