Its compatibility with various materials, including upholstery, carpet, vinyl, plastic, and foam flooring, makes it versatile and practical for boat owners. The product stands out for its pleasant orange creamsicle scent, which is a refreshing change from the typically harsh-smelling cleaners on the market.

The 1-gallon size is substantial, making it a good value for those who need to clean their boats regularly.

Its ease of use, effectiveness, and added UV protection make it a strong contender for anyone looking to maintain the cleanliness and longevity of their boat interiors.

The RMR-86 Instant Mold and Mildew Stain Remover Spray is a powerful, no-scrub formula designed to quickly remove stubborn mold and mildew stains. This product is particularly noteworthy for its fast-acting nature, making it effective for tackling deeply embedded stains on various surfaces such as decks, wood, vinyl siding, drywall, concrete floors, and brick walls. This versatility makes it suitable for not just boat seats but a wide range of applications, which is a significant advantage.

For effective and safe use, proper ventilation and personal protective equipment (PPE) are recommended, indicating that the product can be quite potent and may emit strong chemicals. This could be a concern for users sensitive to harsh cleaning agents or those preferring a more eco-friendly solution. Additionally, the safety precautions required might make it less user-friendly for casual or infrequent cleaning tasks.

On the positive side, the spray's ease of use, with no scrubbing needed, is a huge convenience, saving time and effort. The fresh scent is a pleasant bonus, counteracting the typical unpleasant odors associated with mold and mildew.

Many users appreciate that it rinses away without leaving any residue, helping to maintain the boat seats' appearance without buildup. The gallon size makes it convenient for larger cleaning jobs, which is practical if you have multiple seats or other surfaces to care for. On the downside, while it is safe for many materials, it is intended only for water-safe surfaces, so you should avoid using it on delicate or non-water-safe materials. Also, it may require repeated application and some scrubbing on very stubborn mildew spots.

It does not contain harsh scents or chemicals, making it a safer choice around people and pets. This cleaner is a solid choice if you want a no-fuss, effective product that can handle mildew on boat seats and other similar surfaces, especially if you value safe and residue-free cleaning.
