Formula for Killing Mildew

Moisture Removal

• Before applying any specific cleaners or disinfectants, you must contend with the moisture problem. Mildew cannot grow unless a reliable and persistent source of moisture exists, so determine why you have a moisture issue and then eliminate it. For example, if your home is extremely humid, turn on a dehumidifier. If your shower does not dry properly, open a window or turn on some fans to get the air circulating.

All-Purpose Mildew Killer

• Ammonia, vinegar and baking soda can kill mildew on most household surfaces. While bleach is an equally effective mold and mildew killer, bleach is also highly corrosive, potentially dangerous and a strain on the environment. Just mix one cup of ammonia, a quarter cup of baking soda, a half cup of distilled vinegar and a full gallon of water. Mix the ingredients well. Since ammonia, vinegar and baking soda are all natural, you can use the mixture on almost all household surfaces.

Applying the Formula

• You have two options for applying your mildew-killing formula. First, you can pour the liquid into a spray bottle and use it just as you would use any commercial spray cleaner, zapping mildew wherever it appears. Second, you can apply it to a sponge and scrub the mildew directly. If using a sponge, wring it out as much as possible before getting to work, to avoid applying additional moisture to the mildewed surface. Scrub thoroughly, rinse the affected surface with water and dry.

Considerations

• While this solution is safe for most surfaces, as previously mentioned, some exceptions exist. For instance, never apply this solution to marble, limestone or granite tiles, because acids can ruin these surfaces. For any household surfaces coated with sealants or finishes, read the documentation for the finish to determine whether you can safely use the ingredients. For sensitive surfaces, use a pH neutral cleaner or mild liquid detergent.
