I have a seldom-used powder room where unbeknownst to me, the toilet tank sprang a leak. On discovering the leak, I shut off the water supply and immediately cleaned & disinfected things in a very thorough manner. Everything dried out, and I was sure my problem had been solved. Nope! Apparently the water shut off was faulty and so it trickled just enough to eventually, 3 months later, refill the toilet tank I had previously left empty. Hence, a second leak all over again in the powder room we rarely go into. The only thing that alerted me to the problem this second time was my very sensitive nose smelling something odd when I walked down the hallway nearby. Even though both times the leak was of clean water from the toilet tank and not dirty water from the toilet bowl, now there was clearly a definite problem beyond just drying things out. As a giant germaphobe, I was both extremely stressed out and extremely grossed out by this powder room situation! I wasn't sure what I should do or use, but while Googling I found this product online. I decided to phone the number listed for the Manufacturer to see if this might be the right remedy for my situation. To my surprise, not only did a pleasant person actually answer the phone, but she insisted on transferring me to another woman who was an expert on the product's formulation. I was sure the second woman would feel bothered by my call and give me a quick brush off. Not so! Not only was the second woman welcoming of my inquiry, but she spent a good 20 minutes or more on the phone with me asking me questions about my situation and explaining how best to proceed. I was amazed by the level of customer service this company provided me! I got off the phone feeling confident about making the purchase and using this RMR-141 to treat my powder room problem. It was already very late afternoon so I immediately placed my order through Amazon. Not knowing how much product I'd need, I purchased two of the spray bottle sizes and one of the gallon size jugs. I found it hard to believe, but Amazon said they'd make the delivery by 7am the next morning. Sure enough, it arrived by 6:15am the following morning. I got right to work, heavily spraying my powder room with this product. I followed the woman's advice and did not rinse it off after applying it. (You only have to rinse surfaces that will contact food.) Instead I just let it dry. After the very first application, the nasty, pungent, fungus smell that was formerly noticeable 4 feet away was now totally gone from my powder room. Clearly, this had killed whatever had started growing in there from the dampness. I continued to spray all surfaces two or three times a day, letting them dry out thoroughly between applications. I even sprayed it into the air. I did this for three or four days to be overly cautious, but I'm sure the problem was solved on day one or day two. I was so relieved and so comforted to know that with the kindness of the people at RMR and with their great product, I no longer had anything to stress and worry about. Also, because this is a disinfectant as well as a fungicide, I was no longer grossed out by the thought that anything in the room was still germy from the leak. Important to add is that for a product that's so incredibly effective, it has no chemical smell. There were no harsh fumes or strong chemical odor, and when I got some on my hand while spraying, it was literally as gentle as plain water. This RMR-141 was not only safe to use, but a pleasure to use, knowing that I didn't have to worry about anything scary or caustic. Also, while it has no built-in fragrance, it somehow leaves everything smelling clean & fresh. I LOVED that!!! When I purchased this, I also purchased some empty spray bottles to use it with, since I was sure that the spray bottles this comes in would be cheap junk and hard to use. It seems no matter how expensive a product I purchase is, it's always packaged in the cheapest possible quality spray bottle and my hand becomes a painful claw after the first several pulls of the trigger. Well, my purchase of the empty spray bottles was entirely unnecessary in this case. This product is packaged in what is hands down the best quality spray bottle of any product I have ever bought. It is so easy to use and so easy on the hand. The sprayers have a 'mist' setting and a 'stream' setting. The mist setting provides a dense and even mist. The stream setting literally shoots a powerful stream 4 to 5 feet away. This meant that I could easily spray the entire powder room down without ever having to step inside. This is clearly a company that values quality and thinks about the end user when choosing their packaging. The included spray bottles are excellent quality and they are easily refillable. I'm glad I purchased two. This RMR-141 Disinfectant/ Fungicide worked phenomenally well in tackling my emergency situation. However, based on my experience with it, I think it would be great to use around the house on a regular basis to disinfect surfaces and to keep mold and fungus at bay, and everything smelling clean and fresh. I can see myself using this regularly in my bathrooms and basement and laundry room, or anywhere there might be a musty smell. All in all this was a completely excellent experience. This company's consumer support is second to none, and the product itself is absolutely fantastic!!! By the way, even with all the heavy spraying I did, I only went through the two spray bottles, so I happily have plenty of product remaining. This stuff is worth every penny I paid for it, and more!!! Thank you, RMR!!!!

I LOVE RMR stuffs! I always get RMR-86 because it works so good!! I use it for algae on my outside paver and dilute it with water for the algae/mold on the outdoor pillows and cushions. However sometimes I feel that 86 can be too harsh and the smell is too strong. So I researched a little bit and find this one. I have to say this is my new favorite! It remove the mold/algae same speed as the RMR86 and it barely has any smell!!!!! I also use it for the toilet cleaning, it works so well too!!! Love Love Love!! I spray it, and within a minute the mold/algae starts to change colors and I can easily scrub it off.

I've tried so many products for over 30 years to kill stubborn mold that resurfaces at the tub grout line after I've recaulked. Only RMR 141 has successfully killed the mold. I was truly amazed at the ugly mold mess that oozed out from the crevices between my 1940s tub and tile. Using vinyl gloves, I applied the chemical with saturated cotton makeup rounds followed by a dedicated toothbrush to get the gunk out of the crevices. Two full applications followed by RMR 86 to remove the stains over a 2-day period. Most strong cleaning chemicals force me into a coughing fit, but this one was surprisingly tolerable.

I had some mold forming in our crawl space and decided to try the RMR first before calling in a professional company. I called RMR and they walked me through exactly what needs to be done and to make sure I'm using the correct PPE for the job. I started with the RMR-86 spraying all the areas then following up with the RMR-141 a few minutes later. I let the products do their magic and returned later in the day once all the fumes have settled and found all the spots to be mold free now. It's been almost 3 weeks now since I applied it and all the areas are still mold free. The product is very easy to use but make sure you're using full PPE (Tyvek suite, gloves, goggles and respirator) as this stuff is very strong. Since then I've used these products to spot treat a few mold spots in our shower and had the same great results. Being a smaller area to treat I just ran the bath exhaust fan and opened the window and closed the door. These are great products when used together and RMR has great customer service willing to answer your questions about their products.

This didn’t meet my expectations. The formula I had before would start working as soon as it hit the surface. You could see the soap scum on the tub, tile and grout disappear instantly. However, due to its strong smell, I decided to try this one. I sprayed the surfaces and I waited and waited and then ended up having to scrub the scum out. The toxic fumes aren’t there but neither is the functionality nor speed.

We recently moved into a new home, so we are still learning about it. The first hurricane season in the home, we had consistent rain over the course of two or three days. We noticed water around our "exposed brick" pillar in the kitchen. This was actually an old chimney chute for a wood stove back in the day, and the pillar goes through the entire house. The water was (slowly) running down the pillar, from the roof, through the attic, into the kitchen, until it hit the floor. We were able to clean that up with towels. Luckily, the rain stopped not long after that. All seemed fine until a couple months after and I went to grab a dish out of the cabinet next to the brick. It reaked like mildew. There was nothing visible in the cabinet, so I inspected all around the area. I noticed the cabinetry was pushed up against the brick, and not much was between them. The trim on the countertop also didn't have any sealant to adhere it to the brick. So water had run down into that crack. I wasn't sure how I could clean that up and worried I was about to have a big expense to get someone to rip out the cabinets and clean it. I end up finding this spray instead, and as soon as it came in, I opened it up and read the directions. I put on gloves, sprayed it into the crevice as good as I could, and the cabinets (with dishes removed) and let it sit. Within a day, the scent was gone, and it has not returned. Happy I found this!

This stuff is a kller - literally. Saved me $6k in getting mold out of my crawl space. Bought the goggles, the chem suit, gloves and went to it. Also worked great on dog and cat piss and poop soaked floors to kill bacteria - removed the terrible odor. Quite powerful - sprays more square feet than you would think - used a regular chem sprayer.
