DIY Shower Cleaner Recipe for Sparkling, Streak-Free Tiles

I don’t enjoy cleaning, but I love discovering a cleaner that’s easy to use and actually works.

This homemade shower cleaner is exactly that.

With only three ingredients, you shake, spray, and an hour later your shower looks shiny and refreshed.

It’s simple and effective.

Here are some of the benefits I consistently see with this cleaner:

Penetrates deeply to break down grease, dirt, and grime
Dissolves old, caked-on soap scum
Helps disinfect tubs and showers thanks to the natural properties of the essential oils
Removes hard water spots from faucets, knobs, and door handles
Helps treat and prevent mold and mildew
Leaves tub, tile, faucets, and glass shower doors shiny and sparkling
Smells fresh and clean
Requires very little effort—spray, wait, and rinse. Often no scrubbing is needed; a hot water rinse is enough to reveal a sparkling shower.

White vinegar

16 oz spray bottle — glass bottles work well, or plastic #1 PET or #2 HDPE bottles that are safe for diluted essential oils
Funnel

Homemade Shower Cleaner Recipe

This recipe cuts through soap scum on tubs, tile, and showers with minimal effort.

Step 1: Add 1/2 cup Sal Suds or Dawn Ultra to a 16 oz spray bottle

Note: Sal Suds is a plant-based cleaner from Dr. Bronner’s and is more powerful than Castile soap. Do not substitute Castile soap; it won’t be as effective in this formula.

Step 2: Add 1.5 cups white vinegar

Tip: Leave some space at the top of the bottle for the sprayer and for the essential oils. Filling it completely can cause overflow when attaching the sprayer.

Step 3: Add 25–30 drops of essential oil

Essential oils add a fresh scent and contribute antifungal and antibacterial properties.

Suggested blend:

7 drops lavender
7 drops lemon
7 drops eucalyptus
7 drops tea tree

Step 4: Put the spray top on and gently mix

Secure the sprayer and gently invert or shake the bottle to combine the ingredients.

How to Use

Shake the bottle to mix ingredients
Spray liberally on shower walls, tub, tile, faucets, and glass doors
Let it sit at least 30 minutes; it can sit overnight for tougher buildup
Lightly scrub if needed
Rinse with hot water
Enjoy a cleaner, shinier shower with less effort

Note: Do not use on granite or marble; the vinegar can damage those surfaces.

Caution: As with other soaps, the cleaner may leave surfaces slippery until rinsed.

Why This Cleaner Works

This formula is effective because it combines three complementary cleaning agents:

Vinegar: A natural acid that dissolves soap scum, removes hard water spots, fights mold and mildew, eliminates odors, and helps leave surfaces shiny.

Sal Suds or Dawn Ultra: The surfactant in the dish soap cuts through grease, dirt, and soap scum and helps the solution cling to vertical surfaces so it can work longer.

Essential oils (lavender, lemon, eucalyptus, tea tree): These oils add a pleasant scent and offer antifungal and antibacterial properties that help treat and reduce mold and mildew while deodorizing surfaces.
