How to Clean Toilet Tank Inside, DIY Hacks + Best Cleaners

Keeping your toilet tank clean is an essential part of maintaining your bathroom. Allowing buildup and stains to accumulate can reduce flushing power, unpleasant odors, and potential leaks.

This article will walk through the steps for effectively cleaning your toilet tank.

Benefits of cleaning toilet tank:

  • Prevent mineral deposits and hard water stains
  • Reduce foul odors from bacteria growth
  • Improve flushing power by removing sediment
  • Make toilet parts last longer

What you’ll learn:

  • When and how often to clean the toilet tank
  • What supplies you’ll need
  • How to fully clean the tank, valves, and parts
  • Tips to prevent future buildup

Cleaning the toilet tank is often overlooked, but consistent maintenance keeps all the inner working parts in optimal condition for years to come!

When to Clean Your Toilet Tank

It is recommended to clean your toilet tank every 3-6 months.

For humid environments or homes with hard water, increase the frequency to every 3 months to prevent excessive buildup.

Regular cleaning helps prevent the accumulation of:

  • Rust
  • Bacteria
  • Mineral deposits
  • Unpleasant odors

If you live in a scorching, humid climate, aim to clean the tank at least every three months. The air’s moisture can accelerate mold and mildew growth, which leads to staining and foul odors if allowed to fester.

For those with hard watermineral deposits like limescale can rapidly form. Hard water contains a high amount of dissolved minerals like calcium and magnesium, which cling to surfaces when the water evaporates.

For most households, a biannual cleaning is sufficient. Add it to your list when doing seasonal cleaning routines.

Signs Your Toilet Tank Needs Cleaning:

  • Whitish/yellowish mineral deposits on walls and floor
  • Staining and slimy growth
  • Musty, mildew smell
  • Reduced flushing power
  • Rust forming on metal parts

Stay on top of regular cleaning to prevent major buildup and keep your toilet tank functioning properly.

Getting Started

To access the inside of the tank:

  1. Locate the water valve and turn it off. This stops new water from entering the tank.
  2. Flush the toilet multiple times to empty the tank.
  3. Once drained, remove the tank lid to expose the inner components.

Supplies Needed:

  • Rubber gloves
  • Old toothbrush
  • Mild abrasive cleaner
  • Distilled white vinegar
  • Bucket
  • Towels

The rubber gloves help protect your hands from harsh cleaning chemicals and bacteria.

You’ll need a toothbrush to scrub away grime in difficult-to-reach spots and crevices.

For mineral deposits, distilled white vinegar is highly effective at dissolving them. For more laborious cleaning, an abrasive cleaner with grit helps scrub away grime.

Have a bucket on hand to dilute cleaners or vinegar solutions as needed. Use towels for wiping down surfaces and soaking up excess liquids.

Assessing Cleaning Needs:

Examine the interior of the tank and determine the appropriate cleaner:

  • If there are mineral deposits or hard water stains, use distilled white vinegar to dissolve them.
  • For mildew or grime buildup, use bleach-free disinfectant or abrasive cleaner.
  • For general cleaning, an all-purpose bathroom disinfectant spray works well.

Gather your supplies accordingly before starting to clean.

Cleaning the Toilet Tank

Now comes the fun part—it’s time to roll up those sleeves and get your hands dirty cleaning this puppy!

Here are the critical steps for conquering the inside of the toilet tank:

Assess the Situation

First, take a good look at what you’re dealing with here. Are there just some light mineral deposits and basic grime? Or are we talking about layers of scaled-on hard water stains and even some mildew action happening?

Pro Tip: Inspect along the seams, nooks, and crannies for grime buildup.

Choose your cleaning solutions accordingly:

  • For tackling hard water stains or mineral buildup, you’ll need good ol’ distilled white vinegar to dissolve the deposits.
  • Got grime and mildew? Grab a bleach-free, disinfecting cleaner or one with some abrasive action. This will scrub away the gunk.
  • A standard all-purpose bathroom cleaner will do the trick for routine cleaning or mild buildup.

Always avoid bleach-based cleaners in the tank—they can damage the rubber and metal parts over time.

Apply the Cleaner

For heavy-duty mineral deposits, you’ll want to let the vinegar work its magic:

  • Fill the tank up with vinegar just below the overflow tube.
  • Let it soak for 12 hours so the vinegar can dissolve the scale.

For disinfectants and mild cleaning, spray the product liberally over all surfaces. Let it sit for 10-15 minutes before scrubbing.

Safety Warning: Don protective gloves before handling any cleaning chemicals. Also, work in a well-ventilated area.

Scrub, Scrub, Scrub

Now, here comes the elbow grease portion! Grab your scrub brush or old toothbrush and work that cleaner into the surfaces and grooves.

Getting into those tight corners is vital—use a toothbrush to target them. Scrub the tank walls, floor, and all inner parts thoroughly.

Apply some muscle to lift stubborn stains or gunk. Take your time and do this right.

Flush Away the Grime

Once scrubbing is complete, flush the tank several times to rinse away all the lifted grime and cleaning residue. I like to flush it 2-3 times to ensure a thorough rinse.

Cleaning the Toilet Tank Parts

Now that the tank is sparkling, let’s shift gears and tidy up the inner workings.

Here are some tips for cleaning the toilet parts:

Remove Parts for Better Access

Detach removable parts like the flapperfloat ball, and flush handle to give them a good scrubbing. Also, remove the tank lid if it’s especially grimy.

Taking them out lets you get into all the nooks and crannies better.

Pro Tip: Lay down an old towel and place parts on it to avoid losing small pieces.

Scrub Valves, Siphon & Lever

Use a toothbrush dipped in a cleaner to scrub gently:

  • The fill valve where water enters
  • The flush valve and overflow tube
  • The flapper seal and any chains
  • The flush lever or handle

Focus on eliminating any built-up gunk or mineral deposits.

Handle With Care

These inner components are delicate, so no aggressive scouring!

Be very gentle cleaning rubber pieces like the flapper valve seal. Aggressive scouring can lead to cracks and tearing.

Use a non-abrasive cleaner and soft brush to avoid scratching metal parts like the handle and chain.

Rinse all parts with clean water to remove any cleaning residue. Wipe dry with a clean towel.

Check components for wear and damage. Replace any pieces like the flapper that appear cracked or malformed.

Reattach Parts Securely

Once all parts are cleaned up, reattach them securely in the proper positions.

Double-check that valve seals, flappers, and lids are snugly fitted before turning the water back on.

Final Steps to a Fresh Tank

You’re in the home stretch now! Just a few more steps to button things up:

Reattach Tank Lid

With all cleaned parts appropriately reattached, replace the tank lid. Make sure it sits flush and snug.

Pro Tip: Don’t tighten it down fully if it’s designed to rest on top.

Turn the Water Back On

Locate the water valve and turn it back on to allow water to flow back into the tank. Listen for that welcome hissing sound!

As the tank fills, check around bolts and connections for any leaks. Tighten as needed.

Flush Away Residue

Once full, flush the toilet a couple of times. This rinses away any remaining cleaning product residue.

Clean Exterior

While at it, give the toilet exterior a nice disinfecting wipe-down. Clean the seat, lid, tank, base, and behind the bowl.

Keeping Your Toilet Tank Trouble-Free

You did such a fantastic job getting your toilet tank spick and span. Now, let’s talk about keeping it that way!

Follow these tips to prevent buildup and keep your tank in tip-top shape:

Stick to a Cleaning Schedule

  • Most households aim to clean the tank every 3-6 months.
  • Increase frequency to quarterly for humid areas or hard water.

Do Light Cleanings In Between

  • Wipe down the inner parts monthly to prevent significant grime buildup.
  • Use a toothbrush and vinegar to descale valves as needed gently.

Use Vinegar to Prevent Stains

  • Pour 1-2 cups of vinegar into the tank monthly overnight to prevent hard water stains. Flush in the morning.

Inspect Parts Regularly

  • Check washers, seals, and valves monthly for cracks and wear.
  • Replace parts like flappers immediately if damaged.

Improve Bathroom Ventilation

  • Mix 1 part vinegar with 1 part water for an effective all-purpose cleaner.
