How can I effectively use caulking for toilet repair and maintenance?

To effectively use caulking for toilet repair and maintenance, first, ensure the area around the base of the toilet is clean and dry. Apply a bead of caulk around the base to create a watertight seal. Smooth the caulk with a damp cloth or your finger for a neat finish. Check the caulk periodically for any signs of wear or damage and reapply as needed to prevent leaks and maintain the toilet's integrity.
