I have a 2015 Si and I have tried so many times to get these water stains out of the seats. I've tried brushing it with vinegar, which didn't work. I now just tried using an extractor with Zerorez cleaner, which is supposed to not leave any deposits, but it somehow looked even worse than before after it dried. It seems nothing works to get these seats clean, and the stains are just water deposits. Anybody been able to get theirs clean, and how did you do it?
