While getting rid of musty smells in a bathroom often involves removing mold, many sprays and natural remedies are simply are not enough. That's when we recommend using the RMR-86 Instant Mold and Mildew Stain Remover Spray available at Amazon, which removes deep-set stains in just 15 seconds and begins working instantly.

Whether you need to remove mold from ceilings, grout, or tiles, this spray is suitable for almost all surfaces and comes ready to use with no mixing or scrubbing required. You can also use it to remove green mold and mildew from wooden decks, too. With just a simple spray, watch stains indoors and out disappear before your very eyes.

As one satisfied shopper, Rob, leaving a five-star review, writes, 'This stuff is awesome.I had a weird crevice between my shower door/wall/ floor [with a] buildup of black nasty gunk I couldn’t treat with bleach and a toothbrush scrub.

'I sprayed this product on the affected area and pow! When I came back 15 minutes later, it was 95% gone. Amazing. It does have a chemical smell similar to bleach, but who cares? Spray then walk away. It totally ate up mildew in the lower grout components of my shower tile, too, which scrubbing couldn’t handle. Great product. Highly recommend.'

Though it's worth noting that wearing suitable PPE, such as an adjustable respirator mask, available at Amazon, will help protect your lungs against the harsher chemicals found in strong mold-removers such as the RMR-86 spray. Otherwise, keep the area you're treating well ventilated, and your pets and children out of the space whilst in use and for a while afterwards. The litmus test is whether or not you can still smell it. If so, keep ventilating until clear.

For any spots that do need scrubbing, like cleaning shower tracks, for example, we recommend using the Joseph Joseph CleanTech 3-in-1 Detail Cleaning Brush available at Amazon, which is also one of the best ways to clean shower grout.

Shopper Stephanie agrees with reviewer Rob, and 46,000+ verified shoppers who have left a glowing review on Amazon, describing this spray as a 'powerful mold remover that works instantly.'

She adds, 'I used this spray on mold in my bathroom caused by a lack of ventilation, and it worked exactly as promised. The stains disappeared almost instantly with no scrubbing required. The application was simple, and the results were noticeable right away. All I had to do was spray the problem areas and let it sit and do its job.

'For safety purposes, I opened my bathroom window first, grabbed some goggles and gloves, wrapped my hair, and then I sprayed. Since I was spraying the bathroom ceiling, I wanted to protect myself as much as possible. Also, the smell is strong, maybe as strong as a bleach smell, but make sure to open a window first. It’s rare to find a product that works this well, but this one truly does.'

We definitely recommend using gloves with this product as spray triggers on plastic bottles like the one the RMR-86 spray has can often drip down your finger when you're spraying. The Inspire Black Nitrile Gloves, available at Amazon, are chemical, rip, and puncture-resistant.

A third reviewer, Michelle, dubs this spray 'extremely effective,' and assures that it 'makes bathroom cleaning effortless.' She explains, 'This cleaning spray has been a game-changer for keeping my bathroom clean. I’ve struggled with stubborn mold and mildew stains around grout and corners for years, and this spray works almost instantly without scrubbing.

'Application is simple: Spray directly on the affected areas, wait a few minutes, and the stains fade away. The formula is powerful enough to tackle tough discoloration on shower floors, tiles, and bathroom walls. Even long-standing, dark mildew spots became noticeably lighter after a single treatment.

'I also appreciate that it doesn’t require aggressive scrubbing or harsh tools, which makes the cleaning process faster and less messy. It has a mild scent compared to traditional mold removers, which makes it much more pleasant to use indoors.

'Overall, this spray is powerful, convenient, and reliable. It makes cleaning mold and mildew virtually effortless, and I’ll definitely continue keeping it on hand for bathroom maintenance.'

Don't forget to check behind your couch for mold colonies, too, which is often a hidden spot that could be harboring mold this winter due to a lack of air circulation. Moving your furniture off the wall and allowing a couple of inches worth of space will allow more air movement, and reduce the humidity and still environments where mold spores can take hold and flourish.

What to Shop

It might sound surprising, but there are also things you should declutter to prevent damp in winter, like old magazines and papers.
