How can I properly apply sink caulk to seal and protect the edges of my sink?

To properly apply sink caulk, first clean the area thoroughly. Cut the caulk tube tip at a 45-degree angle and apply a thin, even bead along the edges of the sink. Use a caulk tool or your finger to smooth the caulk and remove any excess. Allow it to dry completely before using the sink to ensure a proper seal and protection.
