We had a sunny day just before Christmas and my grubby windows looked terrible. I got out the windowlene...never before been used...and a couple of j-cloths. I scrubbed and then dried and tried to polish. But I couldnt get rid of the smears, I wish I hadnt started they look worse than before! I thought I remembered something about vinegar so then tried that but again to no avail...
Tips please, what do you use?
