Whats that white build-up around by plumbing fixtures?
The white build-up you see around faucet heads and inside toilet bowls is Calcium Carbonate and Manganese. These elements are healthy and are necessary for proper bodily function. Although the build-up may be annoying, it will not harm you. To dissolve the build-up, you can use a number of commercial solvents (such as CLR) as well as good old-fashioned elbow grease. If you dont want to bother with cleaning it, you can soften your water by purchasing an in-home water softener.
