There are commercial drain cleaners that you can use. However, not all commercial drain cleaners work. Choose the ones that you’ve tried and tested. Most drain cleaning agencies don’t recommend drain cleaners due to health hazards and harm that they cause in nature. The usage of a drain cleaner should be your last resort.
If the situation is only a minor clogging, you don’t need to use heavy-duty drain cleaners. You can use products that are readily available in your pantry. For example, the mixture of baking soda, vinegar, and boiling water can be a de-clogging agent. Pour a cup of baking soda in the mouth of the toilet. Then, pour a kettle of boiling water. Wait for a few minutes. Next, pour another cup of baking soda. Finally, pour a cup of vinegar.
