If your snaking session yields plenty of hair and soap scum, but still leaves you with a slow drain, there's a good chance that the P-trap is still obstructed. To clear it, plug the overflow hole with a rag and fill the tub drain with hot water, which will help to soften and loosen soap scum.
Fats, oils, and grease are such a common cause of slow draining sinks that plumbers nickname them — FOG. Resist the temptation to throw leftover cooking fat down the drain; it will harden and clog. Instead, pour carefully into an empty can, cool, and dispose of it in your regular garbage.

Homes that have older pipes are more susceptible to this happening as hairline cracks and corrosion occur over time. Surprisingly, snaking your main line can potentially make the clog worse.
Some clogs are just so dense that an ordinary hand drain snake cannot force its way through it. In this case, you have little choice but to rent a power auger or call a plumber to do the job. However, don't give up too soon. Being patient and not forcing the auger cable may do the trick.

This type of carbonated beverage usually contains a good amount of phosphoric acid, which given enough time, can eat away at some types of clogs.
In modern houses some of the drain pipes are PVC plastic, and usually the boiling water will just flow through it without causing any damage. But if it goes through the pipe slowly the PVC could the deform.
First, you can run hot water down the drain for 5 to 10 minutes to see if that helps break up the clog. If it doesn't, pour equal parts of vinegar and baking soda into a bowl and then pour that mixture down the drain. Let it sit for 15 minutes, and then run hot water down the drain.
