The 10 Best Ways To Unblock Your Drains
The following are the ten ways that one can get rid of clogging in drain pipes at home, which happens most of the time when grease, food particles, hair, or soap scums tag along in their way.
1. Boiling Water With Dish Soap Method
It’s a very simple yet efficient technique used for unclogging small to medium blockages in kitchen sink drains.
- Boil a kettle of water.

This is a useful natural and chemical-free remedy for clearing out grease and soap clogs.

The method is just great for unblocking sinks with natural homemade unblocked pipes, an environmentally-friendly drain cleaning method.
3. Plunger For Drains
A plunger unclogs bathroom drains and kitchen sinks effectively:
- Fill the sink with enough water to cover the cup of the plunger.
- Place the plunger on top of the drain; press down hard.
