I have some really bad staining where I spilt Teak Oil on my cockpit walls and Lazarette lids. I have scrubbed with boat soap and water, I've tried acetone and Murphy's Oil soap. It's just not coming away. I found a product called FSR which I was told may work. Has anyone used it with success? Or if you have a product you may suggest. I have a buffer tool and I have no problem working it with my hands. Not looking for the easy way out, want something that genuinely works. Thanks in advance.
