If your home has what is considered hard water, chances are you will end up with mineral deposits on your flower pots. You can identify the mineral deposits quickly if you spot some areas on your flower pot that are white and crusty. When you go to transplant your plant or flower, you will want to clean the flower pot and remove the mineral deposits. Fortunately, you probably already posses the items needed to clean the flower pot in your home.
Squirt your flower pot with your garden hose immediately after removing your plant. The power from the hose will help loosen and remove a good portion of the dirt, debris and mineral deposits that are stuck to your flower pot.
Pour 1/4 cup of vinegar in a small bowl.
Sprinkle baking soda in the small bowl while mixing with your spoon. Stop when you have enough baking soda to form a paste.
Spread the vinegar/baking soda paste over the mineral deposits, and allow them to sit for 10 to 15 minutes.
Scrub away the mineral deposits with an old toothbrush, and then rinse the flower pot clean.
Allow the flower pot to air dry before re-using.
