4. Boiling water

This is a simple fix for a clogged bathtub. Heat water to a steaming level and pour it down the drain. Do it in stages giving the water the opportunity to melt the clog. This is one natural way to clear your drain. It takes a few cups of hot water, and it is simple.

5. Drain snake

This is an official plumbing device used to relieve clogs, and many homeowners own one. Occasionally, things will get into drains that run pretty deep, and will not move. This device is able to reach deep into the drain system and pull out clogs.

6. Wet and dry vacuum

9. Dish Liquid

Dish liquid breaks up soap and gunk that clogs drains. It will not affect hair. However, it will loosen the hard surface part of the clog and allow water to move down the drain. It is then possible for the water pressure to push the rest of the clog through.

    you have given a thorough and complete list of aid’s for tackling this project.
    however you and everyone that shares remedies such as these, never know the actual cost of items purchased for the project. like $3 at the hardware store? you’re lucky to get a key made for that price!
    though I still appreciate your suggestions. thank you

      Thank you for your comment.
      Actually for this project, you can get the ziplock/cable tie for $2.99/11-inch 100pk at Harbor Freight, doing a search on their site should give the price.
      We’re always verify the cost mentioned in our post.

      Nope, just sprinkle baking soda all over then pour vinegar atop. Wait a couple minute until all the bubble disappeared then run through them with hot water.

    5 bottles of expensive drain cleaner and dollar store drain cleaner have only allowed a trickle of water to drain. I think the clog is farther down n the pipe system as now the kitchen sink is draining slow too. I will try the vinegar next. I cannot get a snake into my drain as all of them are covered with permanent drop guards to prevent objects from falling into the drains. I have not wanted to take the pipe apart under the sink to gain access (a messy, dirty option, plus due to my age it is not easy to work in awkward places), but I may not have an option if vinegar doesn’t work. One more tip: last time there was a clog, it did not release with hot water from the faucet so I boiled a big pot of water on the stove then poured it into the drain, that finally released the clog.

    We have a severely clogged tub drain. I have in the past used Dawn dish soap and it worked like a hot damn, but today my husband is taking all the water out of the tub cause the leak from the tap slowly fills up overnight. So today, I am going to use vinegar baking soda, and boiling water. hope it works, I need a bath lol. Will update this once the clog is cleared.
