You do not always have to use strong chemicals to remove everything in your bathroom and drains. There are other much more natural options which will do the job significantly better.
The baking soda method with vinegar mixed with boiling water will give you the best results because you won’t see any corrosion on your pipes or anything eating away at them.
With the hair snake method you just need to put the long stick down the drain and the additional spikes and hoops will collect the hair when it is pulled out.
This is a very simple method but is not the most effective out of them all because you might still have the issue of a bad odor smell from where the build up has been there for a while.
When going through this specific method, you need to make sure that you can reach the clog/blockage because if you can’t, this method will not be the best for you.
Using a plunger will help you loosen everything up in the pipe using force. It can be quite solid over time and that needs to be moved around and eventually removed or flushed.
You need to make sure the plunger is fully submerged and you need to forcefully plunge into the drain until you can start to see everything becoming looser.
Then you can lift the snake back up the pipe to see if you have got it all. These are made for more difficult clogs that are harder, so it should work the first time.
