The Marine 31 Mildew Stain Remover & Cleaner is designed for those looking to tackle stubborn mildew stains on boat seats and other surfaces. It's versatile, working not only on boats but also in homes, bathrooms, and patios.

The cleaner is easy to use: just spray it on, let it sit for a few minutes, agitate with a brush or cloth, then rinse and dry. It’s notable for being safe on vinyl, meaning it won’t discolor, dull, or dry out your boat seats, which is a significant advantage for boat owners.

Additionally, it’s fast-acting, removing stains from a variety of surfaces without the need for extensive scrubbing or power washing. However, while it’s effective and easy to use, users should be cautious about the scent, as some may find it strong or overpowering.

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.
