13 best mildew stain removers

Mildew stain removers are cleaning products specifically designed to eliminate and remove stains caused by mildew, mold, and other fungal growth on various surfaces in the home. These products are commonly used in bathrooms, kitchens, basements, and other areas where moisture and humidity can create an environment conducive to mildew growth. Here are some key points about mildew stain removers:

  1. Purpose: Mildew stain removers are formulated to target and break down the stains left behind by mildew and mold. These stains often appear as dark or discolored patches on surfaces like tiles, grout, shower curtains, and even clothing.

  2. Ingredients: The active ingredients in mildew stain removers may vary, but they often include chemicals or compounds designed to dissolve and remove mildew stains. Common ingredients may include bleach, hydrogen peroxide, or specialty cleaning agents.

  3. Application: These products are typically applied directly to the affected area. Users may need to scrub the surface or allow the product to sit for a specified period before rinsing or wiping it away.

  4. Surface Compatibility: It's important to check the product's label to ensure that it is safe for use on the specific surface or material you intend to clean.Some products may be suitable for use on tiles and grout but not on fabrics, for example.

  5. Safety Precautions: Users should follow the manufacturer's instructions and take appropriate safety precautions when using mildew stain removers. This may include wearing gloves and ensuring proper ventilation in the area being cleaned.

  6. Prevention: While mildew stain removers can effectively remove existing stains, it's also important to address the underlying cause of mildew growth, such as moisture or poor ventilation, to prevent future issues.

  7. Variety: There are various brands and types of mildew stain removers available on the market, offering consumers a range of choices based on their specific needs and preferences.

Always read and follow the instructions on the product label, as different products may have slightly different usage guidelines and safety recommendations. It's also a good practice to test a small, inconspicuous area before applying the product to a larger, more visible surface to ensure compatibility and avoid any potential damage.

User questions & answers

Question: Can this be used to clean the mold in the washing machine
Answer: Good Afternoon. RMR-86 should not be used on anything metal, as it is corrosive. RMR-141 could be used to clean the area and kill the mold, but will not remove the stains. If you have any further questions, feel free to call 866-822-8744 or email [email protected]
Question: Would this work on a memory foam mattress
Answer: I wouldn't recommend using any liquid period on a memory foam mattress. Moisture can ruin the foam and not just aestheticly. Think about a kitchen sponge, it never fully recovers to original form once wet and gets worse over time....that's essentially what you're doing to your bed.
Question: My cleaning lady likes to use bleach to clean - is this an effective alternative? Thanks
Answer: The active ingredient in liquid bleach is sodium hypochlorite. The active ingredient in this product is sodium hypochlorite, so it's the same thing, not an alternative. I don't understand why people would pay $17 for 1/4 gallon of bleach and some added surfactant myself. I can buy 5 gallons of 12.5% sodium hypochlorite locally that is a day old or less (bleach degrades and weakens over time and is typically too weak to sanitize around the house about 90 days after it is bought off the store shelf per EPA standards). For the same $17 and have 20x as much, fresher and MUCH stronger than what this is for the same money because this product is probably about 5% or less sodium hypochlorite. I didn't see what percentage of active ingredient was in this product, and I'm assuming that is on purpose.
Question: Does this kill Black mold or does it just beach it
Answer: we had a bunch of black mold on one spot of our house when we moved it. Power washed it, bleached it, tried 30 second stuff and nothing. It just kept coming back. We got this and almost a year later it is still gone. It did take about 3 times spraying it but it was a huge and thick spot. We did not scrub at all due to how high the spot was

It begins working on contact. The special buffered formula will not harm outdoor stitching or threads. It is a better alternative to using regular bleach and contains chelating agents and surfactants to clean better than bleach alone.

For use on most fabrics made for outdoor use like polyester and acylic such as Sunbrella brand; not recommended for use on indoor fabrics, cotton, or clothing. Always test for colorfastness in an inconspicuous area before proceeding with overall cleaning.

PRO TIP: Bleach-based stain removers do not kill mold and mildew, they only remove the stains. For long term mold and mildew stain control, follow with a Chlorine Dioxide-based (ClO2) biocide spray like PERFORMACIDE Mold & Mildew Eliminator. This EPA registered mold, mildew, slime, and fungus killer will not remove stains, so use both products in sequence for optimal results. ClO2 also removes mildew smells and musty odors.

User questions & answers

Question: Can I use this in my attic on rafters and underside of roof sheathing? Is it okay for the roofing nails that penetrate the plywood
Answer: Some work areas like outdoors are already well ventilated, so skin and eye protection are mainly needed. Especially indoors, we still always recommend wearing full PPE when applying RMR-86.

Thank you.

Question: Do I need special protective gear to use this
Answer: Mold, whether in a colony or individual spore has the same cellular structure. This product is disruptive to that cellular structure. So once it is applied to mold, it cannot survive.
Question: Can this be used in a commercial fogger
Answer: Yes, this product cleans mold on all soft surfaces without damaging the fabrics or leather. However, it is not a bleach and will not remove dark stains.
Question: Does it just kill mold, or does it also kill mold spores

Question: how much of this concentrated cleaner do you add to spray bottle? Trying to decide if this is more cost effective than the bottle of spray

You can but this product on Amazon.
Question: As apposed to wiping my kitchen ware like dishes and pans individually with Ec3, Can I soak a few of them together in a solution of this somehow
Answer: It says it’s safe for all pipes and septic systems, if you have a problem and it destroys your pipes or toilet, chances are your pipes were close to being bad anyways but I would still contact the company and make them pay for damages assuming you can prove with a plumbing inspection that this caused your problem

User questions & answers

Question: Can I use this to remove mud from birds on stucco trim above front door
Answer: My personal position is this product is way too caustic and lacks that kind of warning. I am totally dissatisfied also with its performance and lack of warnings in the ad or on the bottle.
Question: Can this be used on boat seats
Answer: Be very careful with this product. What you read before you buy is not as forthcoming as it should be. After receiving you find out all the ad things that will occur when you use it. I t needs plenty of ventilation and will mark items. Be careful
