Removing the old caulk and preparing the surfaces is very important for an effective caulk repair. Here's how to prep the surfaces:
- Remove the old caulk with a handy tool called a retractable razor blade scraper.
- Use the razor scraper to get all the old stuck-on caulk off both surfaces such as the tile and tub. Scrape it clean.
- Vacuum up the debris and vacuum the open joint.
- Once both surfaces are clean and dry, proceed to the next step.
