How to Get Mold & Mildew Off of Caulk

Mold and mildew occur naturally in damp areas. In the home, the bathroom is one of the most common places to find mold and mildew, especially in bath tub or shower enclosures. Because the edges of the tub or shower are where moisture tends to collect, mold and mildew growth on caulk is a common occurrence. Although bathroom mold is usually not one of the most dangerous strains of mold, you should wear a mask while cleaning. Removing mold and mildew from caulk is a simple process that can be managed with items you probably already have in the home.

Things You'll Need

• Household bleach
• Spray bottle
• Soft-bristled brush
• Dishwashing liquid

Instructions

1. Mix 1 cup of household bleach and 1 cup of water in a spray bottle.

2. Spray the bleach on the mold and mildew and allow it to sit for 15 minutes.

3. Scrub the caulk with a soft-bristled brush to remove the mold and mildew.

4. Wash the area thoroughly with dishwashing liquid and cool water. Rinse the caulk and make sure no bleach or soap remains.

Tips & Warnings

• Mildew usually forms in areas that contain soap residue. To reduce its ability to form, clean your shower or tub more often, and rinse the sides and walls after every use.

• Wear gloves and a mask when working with bleach, especially in closed areas such as bathrooms.

• If the mold or mildew has formed underneath or behind the caulk, you must remove the caulk completely and recaulk the area.
