Step 8 · Use a Chemical Drain Cleaner (with Caution)

This is the step people usually slow down on. Go finger-tight first, then a quarter turn. No rush — replay the clip whenever it helps.

Read and strictly follow the manufacturer's instructions on the chemical drain cleaner label. Ensure the area is well-ventilated. Pour the recommended amount of cleaner into the drain. Allow it to sit for the time specified on the product. Flush thoroughly with water. Never mix different chemical cleaners. Use this method sparingly, as chemicals can be harmful to pipes and the environment.
