If you have the time and energy after boring through the clog, clean the sides of the pipe by attaching a finishing tool to the cable and running the full length of the cable down the drain. Then use a hose to run water down the drain as you retrieve the cable.
Waste water may drain out when you open the cleanout and when you break the clog. Stand clear as you remove the plug and as you work on the clog. If the drain line is vertical, place a bucket under the clean-out.
Mix salt and baking soda together. About a 1/2 cup of each and pour down the drain. Let it sit for a minimum of a half hour or as long as overnight. Once it has a significant time, clear it with a pot of boiling water. The tougher the clog, the longer it needs to sit. 6. Plunger. This tactic is mainly for the kitchen sink.
If neither cleaning the trap nor plunging clears a plumbing clog, your final weapon is a drain auger (also known as a snake). This tool, a coiled spiral snake that's usually about 1/4-inch thick with a handle on one end, works the opposite way that a plunger does: You push the snake into the clog
Oh, boy. A stopped-up drain. It'll inevitably happen with any home plumbing system and your kitchen sink is no exception. That clog won't go away on its own and will require immediate attention to keep any standing water from rising. But you don't have to resort to calling an expensive plumber or using a bottle of hazardous chemicals.
Pull the auger or rod back out when the line feels clear and any standing water drains. Reattach the overflow plate, strainer, stopper or trap and run water through the line to wash any remnants of the clog.
