Use a mildew cleaner for mildew spots. I'll use this after first wiping down the seats on my pontoon.During the spring when the pollen is out, I use Dawn and water to first wipe down the seats.During summer, after suntan lotion, I'll clean first with a mild soap with degreaser to remove the suntan oils, then this cleaner.During the final clean up before winter storage, I'll do a deeper clean with some stronger mildew cleaner for those hard spots, then rinse, and clean.I always use a protector after the cleanings. I tried the Aerospace Protestant, the Vinyl Cleaner and I tried the fabric guard. I'm starting to think the fabric guard is great protestant, but still experimenting. So far 12 years on the same seats in the Midwest.
