Spring is here, and with it comes the perfect opportunity for a deep clean. While dusting and decluttering might top your to-do list, tackling hidden grime is equally important. But what happens when you come across unsightly spots on your walls, ceilings, or shower tiles? It could be mold or mildew—and knowing the difference is crucial for effective cleaning and maintaining a healthy home. Let your friends here at LAQ EHS shed a little light on this question about questionable fungi.

What Are Mold and Mildew?

Mold and mildew are both types of fungi, but they differ in appearance, growth habits, and potential health risks. Mildew typically appears as a powdery, flat growth that is white, gray, or yellow. It’s most commonly found on damp surfaces like bathroom tiles, fabrics, or paper.

Mold, on the other hand, is darker and fuzzier in texture, often appearing green, black, or even orange. Mold thrives in areas with excess moisture, such as basements, under sinks, or near leaks. Unlike mildew, mold can pose significant health risks, including respiratory issues and allergic reactions.

How to Identify Mold vs. Mildew

Here are some pro tips to distinguish the difference between mold and mildew:

• Appearance: Mildew is flat and powdery, while mold is raised and fuzzy.
• Color: Mildew is lighter in color, ranging from white to yellow. Mold tends to be darker, often black or green.
• Smell: Mold has a strong, musty odor, while mildew has a milder, less pungent smell.

How to Remove Mold and Mildew Safely

• For Mildew: Use a solution of white vinegar and water or a commercial mildew cleaner. Apply it to the surface, scrub with a brush, and rinse thoroughly.
• For Mold: Wear gloves, goggles, and a mask. Use a mild detergent solution (such as soap and water) and scrub the affected area. If the mold covers a large area, consider consulting a professional.

Preventing Future Growth

• Reduce humidity levels by using dehumidifiers or air conditioners.
• Fix leaks promptly to prevent moisture buildup.
• Increase ventilation in damp areas like bathrooms and kitchens.
