No one likes stepping into a shower and seeing spotting mouldy spots in corner caulking. Here’s what to do about it:
- TRY CLEANING IT WITH VINEGAR. Put white vinegar into a spray bottle (its acidity makes anywhere you spray it an inhospitable place for mould). Spray the vinegar, full strength, onto the mouldy surfaces. Wait an hour, then wipe the area clean with hot water.
- IF MOULD STILL REMAINS, TRY CLEANING WITH BORAX. Borax is a natural cleaner that you will find in the cleaning section in your local grocery or hardware store. Mix 1 cup of borax with one gallon of water. Apply the borax solution with a brush. Be generous as you dab and brush it onto the mouldy areas. Wipe the borax solution and let dry.
- STILL NOT CLEAN? If old, moldy caulking doesn’t get clean, it’s probably time to replace it. Caulking lasts for several years or more depending on ventilation and cleaning habits. The old caulking will have to be removed, and then the area should be properly cleaned before the new caulking is applied. Thoroughly spray the area with the borax or white vinegar solution and let it sit for at least an hour, so it can eat away at all the mould.
Remember that mould grows in areas of poor ventilation, moisture, and darkness so if you have a vent in the bathroom, leave the vent on during, and up to an hour after, a shower.
