Tuesday night as I was sitting on my padded deck chair, (the aluminum cockpit chair with the padded seat and back rest) paging throught the newspaper, I placed the advertisements under my butt to prevent them from blowing away. When I stood up, I noticed the ink from the paper had left marks on the vinyl. I got the Spray nine and went to work but it only lightened it a little and I new a lot more scrubbing would be called for. I looked for the paint thinner which is also great for cleaning vinyl but could not find the can. Then I noticed the bottle of Googone and thought, Why Not? Now, this chair has been out on the patio for a month or so under some trees and I typically sit in it after gardening and lawn mowing so it was filthy. That Googone worked wonders and made that vinyl look brand new. I have read some topics in the past that questioned what type of cleaners to use on vinyl and this had to be the best stuff I have ever used. I am going to take it down to the boat and do the helm and companion seats. I will then give it a shot of 3M protectant afterwards.
