Mildew Stain Removal - Cleaning Mildew From Surfaces

Below you will learn tips and techniques for mildew stain removal and cleaning mildew from fabric, clothing, upholstery, and carpet with step by step instructions.

Mildew is a fungus which grows and thrives in areas which are dark, warm and damp. That means it is common in bathrooms and laundry rooms, and also in wet clothing that is not properly washed and dried, or in carpets and upholstery that gets wet and does not properly dry.

Not only is mildew not fun to look at, it also has a very unpleasant smell and can make you feel sick.

Finally, even when you get rid of the mildew itself (which is no small feat) you may find that the mildew has left behind mildew stains on all types of surfaces, which can be quite difficult to remove.

A note of caution before I begin: Mildew and mold can be harmful to your health, and may also be difficult to remove. If the steps suggested below do not work you may need to call in a professional to both remove the mildew itself, and also for mildew stain removal.

Removing Mildew From Fabric And Mildew Stain Removal From Clothing

Step 1: Take the item outside and there shake or brush off as much of the mildew as possible.

Hint: You want to do this outside because you don't want to spread the mildew and its spores around your home further.

Step 2: Determine whether chlorine bleach is safe for the fabric, or not. If chlorine bleach is safe go to Step 3a, and if not, go instead to Step 3b.

Hint: If you can use chlorine bleach on the fabric this is your best bet, because the bleach will kill the mildew and is generally effective for removing the mildew stain.

Step 3a: If your fabric care label allows the use of chlorine bleach then launder the fabric with laundry detergent and chlorine bleach in the hottest water allowed for the fabric.

Hint: You may want to allow the fabric to soak in the laundry detergent/bleach water inside the washing machine for thirty minutes during the cycle for really tough mildew stains.

Step 3b: If your fabric care label states only color bleach is allowed then you should soak the fabric in a solution of color (or oxygen) bleach and hot water for at least half an hour, and then launder as usual.

Hint: Make sure the mildew stain is gone after washing, but before you place in the dryer or you may set the stain.

The following tips are for really stubborn mildew stains on fabric:

Step 4: Blot hydrogen peroxide onto the mildew stained fabric, then rinse and relaunder.

Step 5: Take the stained fabric out to dry in the sunlight.

Hint: Sunlight is a natural bleaching agent and can both stop the growth of mildew and also, sometimes, bleach away mildew stains.

Removing Mildew Stains From Upholstery

Step 1: Vacuum up as much of the mildew as possible.

Hint: After vacuuming up anything with mildew or mold on it you should replace the vacuum bag or empty the canister immediately, preferably outside.

Further, if it is a washable canister you should wash it out immediately with hot water and bleach to kill any mildew remaining.

Step 2: Mix a solution of one cup cool water and one cup ammonia.

Step 3: Using this solution, sponge the mildew stain with a clean white cloth.

Hint: Ammonia, especially in such a high concentration as suggested here for upholstery mildew stain removal, can be harmful to some upholstery fabrics. Therefore, before using this solution on your mildew stained upholstery you should test it in an inconspicuous area to make sure it will not harm the fabric or fibers.

Step 4: Next, blot at the stain until the liquid is absorbed.

Step 5: Repeat steps 3-4 until the stain caused by the mildew is removed from the upholstery.

Step 6: Now that the stain is removed you should get plain cold water and a new white cloth and sponge the area to remove the cleaning solution, and then blot dry.

Hint: Be sure to get the upholstery only as wet as necessary for mildew stain removal.

Step 7: Aid the drying of the upholstery by using a hair dryer on a cool setting or setting up fans around the upholstery to make sure both the fabric, and the interior of the upholstestered furniture completely dry.

This last step is crucial because mildew can quickly regrow and come back if an area remains damp, so the upholstery must be thoroughly dried to help prevent mildew re-growth.

Hint: If the mildew is not just on the surface, but has gotten deep into the upholstery you will most likely not be able to remove it yourself, and will need to call in a professional.

How To Clean And Remove Mildew In Carpet

Step 1: Vacuum up as much of the mildew as possible.

Hint: After vacuuming up anything with mildew or mold on it you should replace the vacuum bag or empty the canister immediately, preferably outside.

Further, if it is a washable canister you should wash it out immediately with hot water and bleach to kill any mildew remaining.

Step 2: Mix a solution of two cups cool water and one tablespoon of dishwashing liquid (or liquid laundry detergent).

Step 3: Place this solution in a mixing bowl and use an electric mixer set at medium speed to mix the solution to create a foam.

Step 4: Blot this foamy cleaner onto the mildewed carpet, repeating as needed until the mildew stain is removed.

Step 5: Now that the stain is removed you should get plain cold water and a new white cloth and sponge the area to remove the cleaning solution, and then blot dry.

Hint: Be sure to get the carpet only as wet as necessary for mildew stain removal.

Step 7: Aid the drying of the carpet by using a hair dryer on a cool setting or setting up fans around the carpet to make sure both the surface, but also the carpet backing and pad get completely dry.

Just as with cleaning upholstery mildew stains above, step 7 of this process is crucial to make sure the mildew does not return.

Hint: If the mildew is not just on the surface of the carpet, but has gotten deep into the carpet backing or pad you will most likely not be able to remove it yourself, and will need to call in a professional.
