What Is the Best Way to Clean a Bathtub?

An Expert, Eco‑Friendly Guide from The CoBuilders (San Diego, CA)

If you’ve ever searched “What is the best way to clean a bathtub?”, you’re not alone. It’s one of the most common bathroom-cleaning questions homeowners and renters ask—especially in coastal cities like San Diego, California, where hard water, humidity, and daily use can quickly turn a bathtub into a magnet for soap scum, stains, and bacteria.

Many online guides offer quick fixes, but few explain why certain methods work, which products are safest, and how to adapt your approach based on the type of bathtub you have.

• The best way to clean a bathtub (step by step)
• How to clean different bathtub materials safely

This article is written to help you clean better, not just faster.

Why Proper Bathtub Cleaning Matters

Your bathtub is one of the most frequently used fixtures in your home. Over time, it collects:

• Soap scum
• Body oils
• Shampoo and conditioner residue
• Hard water mineral deposits
• Mold and mildew
• Bacteria and germs

In San Diego, mineral-rich water can leave white or chalky residue, while coastal humidity encourages mildew growth—especially in poorly ventilated bathrooms.

Cleaning your bathtub the right way:

• Improves hygiene
• Extends the life of your tub
• Prevents permanent staining
• Reduces mold exposure
• Keeps your bathroom looking fresh and inviting

Step 1: Identify Your Bathtub Type (This Matters!)

Before cleaning, it’s important to know what material your bathtub is made from, because the best cleaning method depends on it.

Common Bathtub Materials:

• Porcelain or enamel-coated steel
• Acrylic
• Fiberglass
• Cast iron
• Stone or composite tubs

Using the wrong cleaner can scratch, dull, or permanently damage the surface.

The Best Way to Clean a Bathtub (Universal Method)

This method works for most standard tubs and is the same approach used by The CoBuilders’ professional cleaners.

Supplies You’ll Need:

• Baking soda
• White vinegar
• Mild dish soap
• Spray bottle
• Microfiber cloth or sponge
• Soft-bristle brush or old toothbrush
• Rubber gloves

Step‑by‑Step Bathtub Cleaning Process

Step 1: Rinse the Tub

Use warm water to rinse away loose dirt, hair, and soap residue. This preps the surface and prevents scratching.

Step 2: Apply Baking Soda

Sprinkle baking soda generously over the tub. It’s a gentle abrasive that lifts grime without damaging the surface.

Step 3: Spray with Vinegar

Spray white vinegar over the baking soda. You’ll see bubbling—this reaction helps break down soap scum and mineral buildup.

Let it sit for 10–15 minutes.

Step 4: Scrub Gently

Using a sponge or soft brush, scrub in circular motions. Focus on:

• Waterline rings
• Corners and edges
• Around the drain
• Textured surfaces

Avoid steel wool or harsh scrubbers.

Step 5: Rinse Thoroughly

Rinse with warm water until all residue is gone.

Step 6: Dry the Surface

Wipe the tub dry with a microfiber cloth. This prevents water spots and future buildup.

How to Clean a Bathtub by Material

Acrylic or Fiberglass Tubs

Best cleaners:

• Dish soap + warm water
• Baking soda
• Vinegar (sparingly)

Avoid:

• Abrasive powders
• Bleach
• Acetone or ammonia

These materials scratch easily.

Stone or Composite Tubs

Acids can etch stone surfaces.

How to Remove Tough Bathtub Stains

Soap Scum

• Baking soda + vinegar
• Let sit for 15 minutes
• Scrub gently

Hard Water Stains

• Vinegar-soaked paper towels placed on stains
• Leave for 30 minutes
• Wipe clean

Mold and Mildew

• Hydrogen peroxide spray
• Let sit 10 minutes
• Scrub and rinse

The CoBuilders avoids bleach whenever possible—it’s harsh, toxic, and often unnecessary.

How Often Should You Clean Your Bathtub?

In San Diego homes near the coast, weekly cleaning is ideal to prevent mildew.

Common Bathtub Cleaning Mistakes

❌ Using abrasive pads that scratch surfaces

❌ Mixing bleach and vinegar (dangerous!)

❌ Ignoring the drain area

These mistakes can shorten your tub’s lifespan.
