How can I effectively clean and restore a moldy terracotta pot to its original condition?

To effectively clean and restore a moldy terracotta pot, start by scrubbing it with a mixture of water and white vinegar. Rinse thoroughly and let it dry completely. Then, apply a solution of water and bleach to kill any remaining mold spores. Once dry, seal the pot with a waterproof sealant to prevent future mold growth.
