After a long winter the vinyl seats had significant mildew staining that I was skeptical anything could fully remove. This product proved me wrong. Sprayed it on β€” let it dwell a few minutes β€” light scrubbing with a soft brush and the mildew staining came off remarkably well. The results were impressive considering how long the mildew had been sitting on the vinyl. One thing to be aware of β€” despite the product not listing bleach as an ingredient the smell is unmistakably bleach-like during application. It dissipates after rinsing but if you are sensitive to bleach smell you will want to work in a well ventilated area or wear a mask. Important tip β€” thorough rinsing after cleaning is essential. Make sure you rinse the vinyl completely and do not leave any product residue on the seats. Taking the time to rinse properly makes a noticeable difference in the final result and protects the vinyl long term. The important thing is it is safe on marine vinyl β€” no discoloration or damage to the seats whatsoever. Followed up with 303 Aerospace Protectant after the seats dried and they look better than they have in years. For anyone dealing with mildew on boat seats β€” especially boats stored in humid environments β€” this product delivers real results. The smell is a minor inconvenience for the cleaning performance you get. Highly recommend.
