Why It’s Important to Clean a Disgusting Bathtub

A bath that looks and feels dirty is unpleasant to bathe in. When grime builds up, it not only looks unattractive, but it also harbors mold, bacteria, and germs that can make you sick. A clean tub is essential for good hygiene and health.

In addition to health concerns, a spotless bathtub also has aesthetic value. Guests will be impressed and more comfortable using a tub that appears well-cared for. And since the tub is a focal point in the bathroom, a pristine white tub (or a tub cleaned to look its best) will make the entire room look crisp and inviting.

If the current condition of your tub makes you cringe, let those reasons motivate you to get scrubbing!

Supplies Needed to Clean a Disgusting Bathtub

Cleaning a filthy tub is an intensive project that requires heavy duty supplies. Here’s what you’ll need:

Cleaning Tools

  • Scrub brushes: stiff-bristled brushes in various sizes to scour every surface
  • Scrapers: to help chip off sticky gunk or mineral deposits
  • Old rags: for wiping down surfaces
  • Pumice stone: to rub off tough stains
  • Goggles: to protect eyes from splashing cleaning products
  • bucket for rinse water

Cleaning Products

It’s better to have all the supplies you need before getting started so you can work efficiently. Clearing out space around the tub will also make the process easier.

Steps for How to Clean a Disgusting Bathtub?

Follow these steps to get your filthy tub sparkling clean.

1. Prepare the Disgusting Bathtub

Start by clearing away any bath toys, shampoos, or other products from the tub area so you can access all surfaces. Remove the shower curtain and liner and wash separately if needed. Drain any standing water from the bottom of the tub.

Check for areas with heavy grime or soap buildup and let them soak for 10–20 minutes with a tub cleaning spray before scrubbing. This helps soften the gunk, making it easier to remove. Open a window or turn on the bathroom fan – you’re going to get up close and personal with that dirty tub, so ventilation helps!

2. Scrub Every Inch of the Disgusting Bathtub

This is the labor-intensive step, but it’s what it takes to remove layers of filth. Use a tub cleaning brush or an old rag dipped in heavy-duty tub cleaner and scrub every surface of the tub, including:

  • Bathtub floor and walls
  • Faucets, handles and spout
  • Shower head connection
  • Overflow drain cover
  • Bottom rim of sliding doors
  • Curtain rod brackets
  • Corner seams and crevices
  • Soap dish and shelves

Take your time and scrub thoroughly to lift away the built-up residue. Rinse scrubbed areas with hot water and repeat scrubbing as needed on tough gunk. Replace the rag or scrub brush head frequently so you’re not just moving dirt around.

For soap scum rings, use a pumice stone after scrubbing to rub away any leftover residue. Vinegar, baking soda, or disinfectant can also help cut through soap scum.

Following are the three guides that can help you clean the bathtub perfectly.

If the base of the bathtub feels like sandpaper, use a mineral deposit remover to smooth it out. Let it soak for 10-20 minutes before scrubbing.

Remove all standing water and continue rinsing, scrubbing, and wiping down surfaces until the tub basin is clean.

3. Disinfect the Disgusting Bathtub

After scrubbing up a storm, disinfect the tub to kill any lingering bacteria. This prevents mold and mildew growth.

Make a dilute bleach solution with 3/4 cup of bleach per gallon of water. Spray or wipe down all surfaces with the bleach solution and let it sit for 5-10 minutes before rinsing. Vinegar is also a natural disinfectant.

If the tub caulking looks black with mildew, spray it with full-strength bleach. Let it sit briefly before rinsing.

4. Rinse Away Cleaning Residue

It’s imperative to rinse the tub thoroughly several times with hot water after cleaning. This removes all chemical residue that could be harmful to the skin.

Take your time rinsing, and wipe down walls and fixtures with a clean, wet rag as you go. Fully drying the tub after cleansing prevents water spots or new mildew growth.

5. Remove the remaining stains and Discoloration

After deep cleaning your tub, stains from rust, hard water minerals, soap, mildew, or other grime may still remain. Here are some tips for removing them:

  • Rust stains – Use a rust removal chemical and scrub with a brush. Let it sit before rinsing.
  • Mineral deposits – Apply vinegar and scrub with a pumice stone.
  • Soap scum – Use baking soda paste and scrub.
  • Mildew stains – Use bleach or oxygen bleach cleaners and re-scrub.

For extra-tough stains, you may need to reapply stain removers and scrub vigorously multiple times to fully lift the discoloration.

Prevent Repeat Disgusting Bathtub Buildup

Prevention is the best way to avoid a repeat cleaning nightmare. Here are some tips:

  • Squeegee the tub after each use to wipe away excess water.
  • Hang shower curtains inside the tub after use so they are fully dry.
  • Use bathroom ventilation fans during and after bathing.
  • Clean the tub weekly by spraying down surfaces.
  • Scrub mildew-prone areas like caulk regularly.
  • Rinse soap dishes and shelves often.
  • Recaulk when old caulk becomes stained and grimy.

Regular light cleaning prevents soap scum, mildew, and mineral deposits from building up again. It’s much easier to maintain a clean tub than tackle heavy grime buildup again later.
