I use lemon juice/baking soda and there is no buildup at all. Living in Fort Worth where the water is quite bad, there has been no calcium buildup to date. Cleaning is going to make a mess no matter how careful you are, it's just the way it is. I know some who do it in the front yard using the garden hose and detergent. A huge mess.
I considered the garden hose as well. LOL
