Gather your tools first. You'll need a pointy instrument to remove the old caulking. A small screwdriver works in most cases. For stubborn caulking, you may need to use a razor knife. You'll also need rubber gloves, mineral spirits, a stiff brush and rags, as well as the new caulking tube, or caulk and a caulking gun.

Clear the tub or shower area in the bathroom that you'll be working in. Remove shampoo bottles, soaps, washcloths, towels, razors, toys, sponges or whatever else is in the area you'll be working in.

Remove the old bathroom caulk by carefully inserting the screwdriver under a loose section of caulking. Pull the caulk towards you instead of trying to scrape it. Scraping it can cause scratches on the tile or tub. Pull as much caulking loose as possible, then use the razor knife for the more stubborn areas in the bathroom. Cut small sections of caulk with the razor knife to remove them.

Clean the area that had the moldy caulking before installing the new caulk. Wipe out the small specks of caulking left with a dry rag. If the area to be caulked is deep, you may need to use a paint brush to sweep it free of the old caulking. Next, remove any old caulking lines with mineral spirits. Dampen a rag and wipe it over the line and use a stiff brush if necessary. Allow the mineral spirits a few minutes to work, then wipe it off with the rag. Remember to wear gloves during this process. Allow the area to dry.

Apply the new caulk using a tube of caulking or a caulking gun. Using a smooth and steady motion, apply a bead of caulk the full length. After you've applied the new caulking, wet your index finger and run it over the new caulk in the same smooth and steady motion. Your wet finger makes the caulk more uniform in appearance. Whether using a tube of caulk or a caulking gun, try to use only one long stroke to apply the caulk.
