How to Clean a Toilet Tank

Introduction

A dirty toilet tank can cause lingering odors, mineral buildup, and poor flushing performance. Cleaning it regularly helps extend the life of your toilet and keeps your bathroom fresher. Fortunately, the process is simple and requires only basic household supplies.

What You'll Need

• Rubber gloves

• White vinegar

• Baking soda

• Toilet brush or scrub brush

• Old toothbrush

• Bucket or cup

• Microfiber cloth

Steps

Turn off the water supply and remove the tank lid.
Flush the toilet to empty most of the water from the tank.
Use a cup or bucket to remove any remaining water.
Pour white vinegar into the tank until the bottom is fully covered.
Add baking soda and let the mixture fizz for 10–15 minutes.
Scrub inside the tank using a toilet brush; use a toothbrush for smaller parts.
Rinse by turning the water supply back on and flushing several times.
Wipe the tank exterior and lid with a microfiber cloth.

Alternative Methods

• Use a commercial toilet tank cleaner designed to remove mineral deposits.

• Add a vinegar-and-water solution and let it sit overnight for heavy buildup.

• Use a diluted bleach solution (only if necessary) — follow manufacturer guidelines.

What NOT to Do

• Do not use undiluted bleach frequently — it can damage rubber components.

• Do not use abrasive tools that can scratch the tank interior.

• Do not mix vinegar and bleach — the fumes are dangerous.

FAQs

Can I use bleach to clean the tank?

Yes, but only sparingly and never mixed with vinegar. Too much bleach can wear out internal parts.

How often should I clean the toilet tank?

Every 3–6 months is ideal, or more often if you have hard water.

Why does my toilet tank smell?

Odors usually come from bacteria, mold, or mineral buildup — cleaning removes these sources.
