Get rid of the hard water ring around your toilet bowl! Use 2 cups of vinegar and sprinkle 2 tablespoons of baking soda and watch the stains start to sizzle away...use an SOS pad to scrub away any stubborn marks/stains.
Another pinner says : "I always direct anyone asking me about my camera (and how to use it) to this site. Its all explained so simply, and taught me how to start using my DSLR. My sister printed it out and keeps it as a reference in her camera bag. Great idea!"
