I wanted to share, that I have made and used the homemade "lime-away" recipe that Nancy shared over at A Rural Farm . Thank you Candy for telling me about it. It's awesome. There are three simple ingredients - vinegar, lemon juice and dish detergent. We have well-water, and even though we have a salt softener tank, we get build up. The kids are responsible for one bathroom, and I the other. My shower is tile, and my homemade tile/grout cleaner does the job very well. However, over in the other bathroom, the shower is a stand-up version, and a cheap one at that. I sprayed it down, and cleared a spot clean. I waited for the kids to come home and showed them. The response? "That really comes off?" Sigh... "Yes kids, that really comes off." Now they have no excuses. Recipe: Fill a spray bottle half-full with white vinegar; add 1/4 cup lemon juice, then fill the bottle the rest of the way with dish detergent. ...
