More advice
Our dodger had new windows replaced 8 years ago. When I asked what to use to clean it he said only water. I wash them with water, wipe with a clean cloth while they are wet, rewash with only water, then dry with a very clean cloth. The windows are like new. One other step I use as we have hard water down here in the Marina, is to do a final rinse with bottled or distilled water before drying. I simply use a spray bottle of distilled water to wipe away the mineral deposits, then dry. Been pleased with this advice. Perhaps badly crudded windows might need more aggressive treatment.
