How to recaulk a bathtub properly?

To recaulk a bathtub properly, first remove the old caulk using a caulk removal tool. Clean the area thoroughly with a mildew remover and let it dry completely. Apply new caulk in a smooth, continuous bead using a caulk gun. Smooth the caulk with a wet finger or caulk tool. Allow the caulk to dry completely before using the bathtub.
