As a rental property owner or tenant, dealing with a clogged sink or tub is a frustrating but common issue. Many people reach for chemical drain cleaners immediately, but these harsh products can cause more problems than they solve. Over time, chemicals can corrode pipes, damage fixtures, and create harmful fumes. That’s why property owners and tenants alike should know safe and effective ways to clear drains naturally.
In this guide, we’ll walk you through simple steps to unclog a sink or tub drain without resorting to toxic chemicals.
Why Avoid Chemical Drain Cleaners?
Chemical drain openers often contain sodium hydroxide or sulfuric acid, which generate heat to break down clogs. While sometimes effective, these products can:
- Erode pipes – Prolonged or frequent use weakens plumbing, especially in older rental homes.
- Damage finishes – Splashes or spills can stain sinks, tubs, and countertops.
- Pose health risks – Fumes irritate eyes, skin, and lungs.
- Harm the environment – Chemicals that enter the water system affect local ecosystems.
For these reasons, professional property managers and plumbers generally recommend mechanical or natural methods as the first option.
Step 1: Boiling Water Flush
Boiling water is one of the simplest solutions. Most clogs are caused by grease or soap buildup that softens with heat.
How to do it:
- Boil a full kettle or large pot of water.
- Slowly pour the boiling water directly into the drain in two to three stages, allowing it to work for several seconds between pours.
This can quickly clear minor blockages, especially in kitchen sinks with greasy residue.
Step 2: Baking Soda and Vinegar
This natural method is a favorite. Baking soda breaks down grime, while vinegar’s reaction pushes debris through.
How to do it:
- Pour ½ cup of baking soda down the drain.
- Follow with ½ cup of white vinegar.
- Let the mixture fizz for 10–15 minutes.
- Rinse with boiling water from a kettle.
This method works well for soap scum, light hair buildup, and deodorizing drains.

Step 3: Use a Drain Snake or Zip-It Tool
If hair is the primary issue, physical removal is the only effective solution. A drain snake or inexpensive plastic tool is very effective.
How to do it:
- Insert the tool into the drain.
- Wiggle and pull upward to catch hair or debris.
- Repeat until the drain is clear.
- Flush with hot water afterward.
This option is especially useful in bathroom sinks and tubs, where hair clogs are a common issue.
Step 4: Try a Plunger
Plungers work on sinks and tubs by creating suction and loosening deeper property clogs.
How to do it:
- Fill the sink or tub with a few inches of water.
- Place the plunger firmly over the drain.
- Pump up and down vigorously several times.
- Test the drain to see if water flows.
For double sinks, be sure to block the other drain with a wet rag to maximize suction.
Step 5: Clean the P-Trap
If the above methods fail, the clog may be in the P-trap—the curved pipe under the sink. This trap collects debris and prevents sewer gases from escaping.
How to do it:
- Place a bucket under the P-trap.
- Unscrew the slip nuts on both sides of the trap.
- Remove the trap and clean out debris.
