At recommended use dilutions it will be ok near plants, shrubs, and flowers. It is recommended to first wet the plants just with water, proceed to clean the surfaces nearby then rinse the plants off afterwards with fresh water. Do not dispose of the concentrate in ponds, waterways or ditches.

      does this work with caulk around bathtub??
      ByOct 1, 2025
      1 Answer | 
      Answer This Question

      Hi Quimby, Depending on what type of caulk it is it could work. Since the formula is water based if the caulk is silicone based it would not penetrate the caulk.

              Answer This Question

              Hello AnnK! Thank you for your question! While this is a great formula for outdoor applications, we recommend using this product only as directed on the label. Spray the product on your stain with a spray bottle, let it penetrate to work on the soil, and then you could use pressurized water to clear or wipe with a clean sponge or cloth.

                Is this ok to use on polymeric sand? Specifically I’ve got flagstone with poorly installed polymeric—it’s only a half inch deep in the joints and many of the joints are six inches wide.
                ByFeb 12, 2025
                1 Answer | 
                Answer This Question

                Hello Echoio and thank you for this question. This product is great for natural stone surfaces. If you are concerned about the integrity of the polymeric sand you should try the product on a small inconspicuous spot before applying it to the whole area and scrub gently with your cleaning application of choice.

                  Amazingly easy!
                  I had a patio umbrella that had so much green mold/gunk on it that I was ready to throw it out. Before doing so I decided to try cleaning it. A helpful employee at HD’s Cumberland sore recommended this and wow! I’m so glad I tried it. Applying it with a spray bottle, and letting it sit just a few minutes produced amazing results, even before rinsing. I’ve since used it on resin lawn chairs, tile shower walls, and this weekend will use it on our vinyl siding. I will now always have this cleaner on hand.

                    Quick, easy and very effective!
                    Living in South Florida we are constantly battling mold and mildew on many exterior surfaces. We need a product that cleans dirt, mold and mildew from concrete, stucco, aluminum pool, enclosures and painted surfaces. This Ecolab cleaner makes very quick work of cleaning all of these surfaces! Depending on the amount of mold and mildew and type of surface some amount of scrubbing and wiping may be required, but in many cases all you do is apply the cleaner and rinse clean. You can use pretty much any type of sprayer to apply the cleaner, or you can pout it on the area to be cleaned but you will use more of the product than you need with that application process. The before and after pictures shown below show a portion of our concrete pool deck that, because of the tilt of the deck, collects dirt and moisture, leading to mold and mildew. We simply sprayed on the Ecolab cleaner and you could immediately see it removing the dirt, mold and mildew from the area. We let it sit for about a minute, used a long-handled scrub brush a few times and rinsed it clean with the hose. The cleaner worked great! We are very pleased with how quick and easy it is to use and with the results!

                    It works!
                    My Ecolab 1 Gal. Mold and Mildew Stain Remover was shipped to the house. I was pleasantly surprised when I opened the box to find it enclosed in an additional sealed plastic bag in case it leaked in transit, nice touch HD! I decided to try it on a problem area just outside my shower that has seen repeated water damage as seen in the before and after pictures attached. I was concerned by the black discoloration at the bottom of the trim and knew I needed something that would not only clean the surface but pernitrate the trim to kill what was growing. I poured some product into a disposable plastic cup and applied the product with a old toothbrush so I could better control the application. I was glad I had the bathroom fan on because it had a very bleach like odor. I let is sit for about a minute, brushed again and let it sit for another minute before wiping it down with a wet rag. Great results and it couldn't have been easier!

                    Quite good!
                    Great product! ECOLAB has several new cleaning products that I've noticed pop up in Home Depot recently and I thought I'd give this a try. So far, this Mold and Mildew stain remover works really well. I have one room the house that tends to get a bit musty over time. I live near the coast, so humidity and moisture allows for mold/mildew to thrive. I used this product to clean the floor [vinyl] and walls, and it really freshened up the room. Didn't use full strength, but rather 1 cup in a gallon of warm water, and then applied it with a clean floor mop. Used a large sponge for the walls. Instructions say to let it sit for about 1 minute if needed, then rinse/wipe down with water. Has a mild "detergent" like scent. It does not have a bleach scent even though one of the listed ingredients is sodium hypochlorite. Directions state that it can be used for indoor or outdoor applications on multiple surfaces including showers/tubs and tile, in kitchens, etc. Similar to bleach, it recommends avoiding direct contact with clothing/fabrics, wood, rubber, and/or painted surfaces which it could cause discoloration. Product is ready to use (no mixing/diluting required), has a semi-clear water-like consistency, and made in the USA! Looking forward to trying some of the other ECOLAB products soon.

                    Good, but not great
                    We got this cleaner for an outside job on our patio - a buildup of mold after all the rain we've had. It worked well, but the directions say to just spray and rinse. In our case, on the patio bricks, some scrubbing was definitely required. Cleaner is not concentrated, you can use it straight out of the jug. Medium strong bleach smell.

                    Gets the job done better than other detergents
                    So after this years above average rainfall i had a ton of algae/mold around my house, sidewalks, patio trim and usually i have to gear up, spray bleach/cleaners and aggitate before i hose off the house surroundings. This year i thought i would try something different and give ECOLAB Mold and Mildew Stain Remover a go. I was able to load it in my canister went to town on my backyard and walkways full of algae and mold. After a few minutes of spraying i started to get a little skin irritation on hands and eyes, so i geared up and continued. I did as directions stated and sprayed generously on affected area and let sit, i came back with a stiff push broom to aggitate and then spray again and let sit for 5 mins or so and proceeded to rinse with jet stream water hose and to my surprise, it cleaned up way better than imagined. I then took inside to clean my tub but i felt it was too strong chemically for my indoor situation but it cleaned the shower grout pretty effortlessly. Besides the chemical smell and irritation that comes with working with all chemicals it sure does clean a lot easier than using manual elbow grease. I will continue to use and see what else Ecolab has to offer.

                    Cleaner works OK
                    As far as cleaners go. this one is OK, not bad, but not great. It's bleach based and not concentrated, you can use it straight of the bottle. We got this product for the mold on our front patio bricks. With all the rain we've had the past couple of months, we had quite a build up of mold. The directions say to simply spray on and rinse off, Well, that didn't work for us. No question that I had to scrub the bricks with a hard bristle brush to get the mold off. It definitely helped, but it wasn't the end all be all. Perhaps it works better on the mold on the grount in a tiles shower. We'd try it but were pretty OCD about cleaning the shower and don't have any mold.

                    Safe and easy to use on tough stains
                    ECOLSAB 1 gallon mold and mildew stain remover. Only three ingredients of this product are listed but when I opened the cap there was a strong chlorine smell. The first ingredient is water indicating that it is not concentrated. I used the product in a pump sprayer to clean white painted steps. The steps were stained with mold and dirt. After spraying a generous amount, I let the product set in the sun for at least an hour. I used a strong spray of water to rinse the product off the step and most of the mold and dirt came off. Next I used a stiff bristle broom to scrub the step. The final result was a bright white surface with minimal amount of effort. The product gives the impression that it is ecofriendly. It is made in the USA and there are several ways to contact and get information on the company’s products. The container lists surfaces that are suitable for the product and also surfaces and materials to avoid such as clothing, fabrics, wood, rubber and painted surfaces to avoid discoloration. The product is safe to use indoors or outdoors.

                    Ecolab Mold and Mildew Stain remover barely does the job.
                    Mold and Mildew Stain remover is a liquid bleach-powered professional grade cleaner formulated to remove the toughest stains caused by mold, mildew, dirt, grime, soap scum and other soils. This is information from the write up on the Home Depot Site. Why 1 star? It is the lowest grade we could give. I did a side by side comparison of basic brand bleach and Ecolab. Here are the results. The bleach and Ecolab both destroy clothing and materials. The Ecolab claims: No personal protective equipment required for use. It will make your eyes water and burn and your nose too. The bleach cleaned better than the Ecolab. The bleach removed more stains. After letting both sit for several minutes wiping down and rinsing with water. See photos. Bleach can be used to disinfect; I would not use Ecolab for this. Ecolab will lift paint of your appliances. But it is safe to use on plastics? We were not impressed, nor would we recommend this product. Save your money. This is not a product to use for the results that basic bleach can do.
