Gentlemen,

I need your help before SWMBO blows a gasket. We have a red terracotta colored patio and without going into details of why or how, I spilled some vinegar on the patio. Now I have white spots all over and I am wondering if any of you know a good method of removing the offending stains. I have already tried ample water and elbow grease to no avail. Your help will be greatly appreciated. Thanks.
