Is a dull white film covering your outdoor flagstone? Cleaning flagstone doesn't have to be a hard chore.  Here's an easy solution to bring it back to life.

To keep your flagstone flying high, use some elbow grease to scrape away wax build up. Then follow up with a brass bristle wire brush dipped in one part pool acid and 20 parts water. This should bring your flagstone surface back to its original glory days.
