Mildew refers to certain kinds of mold or fungus. The term mildew is often used generically to refer to mold growth, usually with a flat growth habit. Molds include all species of microscopic fungi that grow in the form of multicellular filaments, called hyphae.
Differences Between Mold and Mildew
Mold tends to have a higher profile and can even become fuzzy, while mildew is usually flat. Mold exhibits darker colors such as deep green and black; mildew may begin as white, then turn brown or gray.
Mildew and mold are both fungi, but mildew is not as invasive or troublesome as other types of mold. Typically found in wet areas, mildew looks grayish-white and may turn brown. It's flat and powdery and it's an easier fungus to clean because it lives only on the surface of a material (such as bathroom tile).
Use undiluted white vinegar on hard surfaces in kitchens and baths. A bleach solution also works to kill mold. Mix one cup of bleach in a gallon of water, apply to the surface and don't rinse. Mix a 50/50 solution of ammonia and water.
While it is possible to use bleach to kill mold as well, experts agree that vinegar is a much better option. Unlike bleach, vinegar can effectively kill the mold at the root, which means it's less likely to return. Vinegar is also less toxic than bleach, making it a better choice for household use.
Bleach can contribute to further mold growth
Bleach is made up of about 90 percent water. Moreover, since molds thrive with moisture, spraying bleach on mold can contribute to further mold growth, especially on porous (permeable) surfaces.
No matter how much you clean, it's basically inevitable: There's always something growing in the bathroom. Mildew and mold are incredibly common, popping their unwanted selves into bathrooms, crawl spaces, and basements.
If your shower isn't properly sealed, you're at risk for mould and mildew growth. Mould not only looks terrible in your shower, but it's also a health hazard.
Scrubbing with vinegar or a borax solution is a great way to clean mold from bathroom tile. For small applications, mix 2 tablespoons borax into 2 cups warm water and funnel into a spray bottle. Spray the solution on tiles and let it sit for a few minutes.
“It's very important that if you see this type of mold — which is usually dark green or black in color and, really, texture-wise it's kind of slimy — that you avoid the area because if that starts to break off, the mold spores can be very harmful,” he said.
Common symptoms of mold include coughing, sneezing, postnasal drip, nasal congestion, and itchy eyes, among others. To prevent these symptoms, black mold in showers should be removed promptly, as should any other form of mold in bathrooms.
It's wet, damp and dark at times. It can grow on walls, in baths, showers, carpets, wallpaper, grout, wood, sinks and toilets. The most common causes of bathroom mould are lingering moisture caused by lack of ventilation, leaky toilets, sinks and plumbing pipes, as well as damp cellulose materials.
Without a doubt, mold is worse than mildew. According to American Home Shield, “the difference between mold and mildew is that unlike mildew, certain types of toxic molds can result in serious health problems for you and your family.” Black mold, in particular, is dangerous for humans.
Mildew is considered an early stage of mold, though it is not as common as mold. It thrives in moist environments and often looks like a powdery substance.

If you're not wearing any Personal Protective Equipment (PPE), you're inviting all of those mold spores to settle on your clothing, the area you're cleaning, your shoes (allowing mold to travel to other areas in your home), in your eyes, and up your nose into your upper respiratory system.

While a significant mold infestation is best handled by a professional restoration company, you have a powerful weapon against occasional mold growth in your kitchen cupboard: white vinegar. This humble household staple can kill more than 80% of mold species, including hazardous black mold.
Distilled white vinegar is non-toxic but acts much more slowly than chlorine bleach or hydrogen peroxide. While it will kill the mold, the discoloration and stains may remain and require additional scrubbing with a household cleaner. Distilled white vinegar can be used safely on most porous and non-porous surfaces.
