Clean and Disinfect the Area

What happens here

Once the bulk of the old caulk is removed, the presenter uses a purple rag to wipe away loose debris. He then sprays a solution of water and bleach from a spray bottle along the cleaned caulk lines. This is done to kill any lingering mold or mildew spores. After spraying, he uses a paper towel to thoroughly wipe down and dry the area, ensuring it's clean and ready for the next steps. He notes the strange discovery that the tub and tile appear to have been painted over, as flakes of paint are also coming off.

Goal: After removing most of the old caulk, the presenter cleans the area with a rag, then sprays a bleach and water solution to kill any remaining mold or mildew, and finally wipes it dry.
