How do I properly apply caulking around a bathtub to prevent water leaks and maintain a secure seal?

To properly apply caulking around a bathtub, first clean the area thoroughly and remove any old caulking. Cut the tip of the caulking tube at a 45-degree angle and apply a smooth, continuous bead along the joint between the bathtub and the wall. Use a caulking tool or your finger to smooth the caulking into the joint. Allow it to dry completely before using the bathtub. This will help prevent water leaks and maintain a secure seal.
