Tips & Warnings
To prevent future staining, consider applying a sealant to the granite landscape stones to prevent stains from forming in the future.
If the stain is from rust, or is just hard to remove, place hydrochloric acid in a bucket and add enough water to dilute it to 10 percent. Put on rubber gloves and a face mask and scrub the stains until they are removed. Rinse thoroughly afterward with a garden hose.
