DIY Tip of the day – Moldy bathtub/shower caulk

Using a 5-in-1 tool and a plastic razor to cut, scrape, and remove all of the existing caulking. You want to remove every last piece so you can get a good seal with the new material and prevent moisture from getting back there. If you do not make a good seal mold can and most likely will form again. Once the joint is cleaned of prior caulking apply new acrylic latex caulk containing mildewcides.
