Hi, this is Digger, on Snoopy-C. I've been trying to clean my cruiser's windows, and am having some difficulty. The boat has been used in salt conditions, but mostly in eastern Washington. I thought that there were hard water spots, but I now am thinking that the spots are more like pits. The only thing I've been able to address the spots with is the ceramic stove-top cleaners, and huge amounts of elbow grease to clear the spots. I could wash the whole boat by the time one window is cleaned up. Are there any solutions that any of you have employed with similar problems? :crook Thank you for any input. :thup
