Before beginning, assemble all necessary tools and safety equipment in the immediate area. Common equipment includes pliers, a plunger, a drain snake, rubber gloves, and, if needed, protective goggles. Having absorbent towels on hand can help manage water spills. If you plan to use chemical drain cleaners, it’s essential to ensure good ventilation and readiness to handle any accidental splashes safely. Preparedness minimizes interruptions and lets you focus on the unclogging process itself.
