The Mold Stain Remover Gel Cleaner by ACTIVE is designed to tackle mold stains effectively, particularly in high-moisture areas like front loader washing machine seals, bathroom grout, and shower caulking. One of its main strengths is its fast action, often showing results within minutes, making it suitable for those who need quick cleaning solutions.

It’s versatile enough to be used on various surfaces including rubber gaskets, laundry drums, and refrigerator seals – making it a good multi-purpose cleaning product. The product is free from harsh chemicals like ammonia and Bisphenol A, contributing to better safety for home use and a more gentle odor compared to other products in this category.

The effectiveness and duration of the result might vary based on the severity of the mold stain and the type of surface. The 7-ounce bottle is concentrated and claims to last up to a year, but this could be insufficient for larger or heavily stained areas. While it is unscented, which might be preferable for sensitive users, some might miss the fresh scent that other cleaners provide. This mold stain remover gel is very effective for targeted cleaning and safer due to its gentle ingredients, but users should note its limited volume and manage expectations based on the extent of the mold problem.

The product has a fresh scent, which is a plus if you’re sensitive to strong chemical smells. However, because it’s a professional-strength formula, it’s important to use proper ventilation and personal protective equipment during application to ensure safety. While the spray is effective at removing stains and odors left by mold and mildew, the need for safety precautions means it might be better suited for users comfortable following these guidelines.

Since it comes in a large one-gallon container, it’s a great choice for bigger jobs or frequent use but might be more than needed for small or occasional tasks. For those seeking a powerful, no-scrub solution for mold stains across many surfaces and who are willing to follow safety steps, RMR-86 presents a solid option.

However, at 256 fluid ounces and a weight of 17.68 pounds, the product is quite bulky, which might pose storage challenges for some users.
