Remove Old Caulk with Scrapers

What happens here

Initially, the presenter tries using the silicone trowel scraper to remove the old caulk along the bathtub's edge. He notes that the plastic material of the tool is too soft and doesn't effectively remove the stubborn caulk. He then switches to a metal 14-in-1 painter's tool, which is much more robust. He uses the sharp edge of the painter's tool to vigorously scrape along the caulk lines, successfully removing pieces of the old, hardened material. He mentions the importance of thorough removal to ensure proper adhesion for new caulk.

Goal: The presenter attempts to remove the old caulk using a silicone scraper but finds it ineffective due to its plastic nature. He then switches to a metal 14-in-1 painter's tool, which proves more efficient at scraping the old, hardened caulk.
