How to Clean Your Toilet Tank: A Step-by-Step Guide

When it comes to keeping bathrooms clean, we often focus on what’s visible: the toilet bowl, sink, and mirror. But have you ever thought about what’s lurking in your toilet tank? Many people are surprised to learn that their tank can hold mineral deposits, mildew, and bacteria, especially in areas with hard water, like Murrieta. Cleaning it regularly isn’t just good hygiene—it can keep your toilet working more efficiently and extend its lifespan. Here’s a quick, easy guide from Donnie’s Plumbing in Murrieta to get your tank sparkling clean.


Why Clean Your Toilet Tank?

Over time, minerals and sediment from hard water can build up inside your toilet tank, affecting performance and causing corrosion. Regular cleaning keeps everything running smoothly and prevents costly repairs.


What You’ll Need

  • White vinegar
  • Baking soda
  • Rubber gloves
  • Sponge or scrub brush (one you don’t mind using just for this!)
  • An old toothbrush (for hard-to-reach spots)
  • A bucket or large cup

Step 1: Turn Off the Water Supply

Find the shut-off valve behind the toilet and turn it clockwise to stop water flow. Then flush to drain the tank. Hold the handle down to empty as much water as possible.


Step 2: Apply Vinegar and Baking Soda

Pour a cup of vinegar into the empty tank and sprinkle baking soda in. The fizzing action helps loosen grime and mineral buildup. Let it sit for 10–15 minutes (or longer if it’s really dirty).


Step 3: Scrub the Inside of the Tank

Put on gloves and scrub all surfaces inside the tank, especially the corners and hardware. Use the toothbrush for small or hard-to-reach areas.


Step 4: Rinse the Tank

Use your bucket or large cup to pour water into the tank and rinse away any remaining grime or vinegar solution.


Step 5: Turn the Water Supply Back On and Flush

Turn the shut-off valve counterclockwise to refill the tank. Once it’s full, flush a few times to clear everything out. Make sure the toilet is functioning normally.


How Often Should You Clean Your Toilet Tank?

Twice a year works for most homes, but in hard water areas like Murrieta, every 3–4 months is better to prevent buildup.
