Window spot cure

Recently posted a need for help cleaning 3 years of water spots off the windows of my Winnebago View. 0000 steel wool with maguires window spot remover did an unbelievable job. I took one section at a time and put the cream on the steel wool and scoured the window. In no time they were clean, polished and NO scratches. After I cleaned them with a clean dry towel, I went back and touched up the places where spots remained. I finished by washing the window with regular window spray and everything looks new and the spots that drove me nuts for so long are gone. Thanks for your replies and help. McD is a happy camper again....
