How to Deep Clean a Shower the Right Way (for Tile, Fiberglass, Acrylic and Stone)

Every tip here is checked against the sources listed at the bottom.

An emptied shower with white tile walls, a foamy cleaner sitting on one wall, a long-handled non-scratch brush leaning in the corner and a squeegee on a hook

The short answer

What works Find out what your shower is made of, because stone, acrylic and fiberglass each have cleaners they cannot take. Then take everything out, put on a bathroom cleaner made for your surface and let it sit. Scrub with a non-scratch brush, rinse well and buff it dry.

How long
Most of the work is scrubbing, rinsing and drying. The cleaner needs the sit time on its label, and a mildew spot on grout needs 10 minutes with a bleach mix.
What it costs
At Target.com on November 7, 2026, a tile and grout brush was $2.69 and a squeegee was $5.49. A 20 oz can of Scrubbing Bubbles Bathroom Grime Fighter was $3.79.
What you need
Gloves and a bathroom cleaner that is safe for your surface. You also need a non-scratch brush or sponge, a soft grout brush, a cup for rinsing, a dry towel and a squeegee.

Before you start: what is your shower made of?

Every shower cleaner is safe on some surfaces and harmful on others. Check yours first.

  • Glazed ceramic or porcelain tile. The American Cleaning Institute says to use a nonabrasive tub and tile cleaner, and to skip powdered abrasives that could scratch.
  • Fiberglass. The American Cleaning Institute says to use a tub and tile cleaner or baking soda, and to avoid abrasive cleansers and pads that could scratch or dull it.
  • Acrylic. It scratches too. The American Cleaning Institute says to use a cleaner made for acrylic, or warm water, and dry it with a soft cloth. Some foaming cleaners say they are not for acrylic, and Scrubbing Bubbles Bathroom Grime Fighter is one of them.
  • Natural stone, like marble, travertine or limestone. The Natural Stone Institute says lemon, vinegar and other acids may dull or etch these stones, and scouring powders may scratch them. Use a mild dish soap and warm water, a stone soap or a non-acidic soap scum remover.

Step by step

  1. Take everything out

    Move the bottles, razors, sponges and caddy out of the shower. Clorox says to remove everything from the shower and tub first.

  2. Get air moving and put on gloves

    Turn on the bathroom fan or open a window, and leave it on the whole time. Put on rubber gloves. Clorox says to wear gloves and keep good air flowing when you clean with bleach.

  3. Wash the shower curtain liner

    Take down the liner. If it is machine washable, Clorox says to wash it in warm water with a mild detergent. It can run in the washer while you clean the shower.

  4. Put on the cleaner, then wait

    Spray your surface-safe cleaner over the walls, the tub or shower floor, and the shelves. For Scrubbing Bubbles Bathroom Grime Fighter, the label says to spray from 6 to 8 inches away and let the foam soak in. On heavy grime, the American Cleaning Institute says to let a cleaner sit at least 30 seconds to loosen the dirt.

    On natural stone, wash with warm water and a mild dish soap instead, or a cleaner made for stone.

  5. Scrub the walls, tub and grout

    Scrub the walls and tub with a non-scratch brush or sponge, using small circles. Then use a soft-bristle brush on the grout lines, which the American Cleaning Institute recommends.

  1. Rinse everything well

    Rinse every surface with plenty of clean water, using the hand shower or a cup, until no foam is left. The Scrubbing Bubbles label says to rinse chrome with water, and the American Cleaning Institute says to rinse tile thoroughly.

  2. Treat any mildew spots on tile grout, separately

    If dark spots stay on glazed tile grout, the American Cleaning Institute says a bleach solution or a mildew stain remover can be brushed on and then rinsed. Clorox says to mix 1/3 cup of its bleach into 1 gallon of water and keep the spot wet for 10 minutes. Then rinse well.

    Do this only after the first cleaner is rinsed away, and never on marble. Dark spots in the caulk need How to get mold stains off shower caulk.

  3. Buff it dry

    Dry the walls, tub and fixtures with a clean, dry towel. The American Cleaning Institute says buffing with a dry cloth keeps water spots from forming.

  4. Put it back and leave it open to dry

    Hang the clean liner back up, put back only the bottles you use, and leave the shower door or curtain open. The American Cleaning Institute says to keep shower doors ajar so air can move and mildew has a harder time growing.

    Keep it clean between deep cleans: dry the walls after every shower. The American Cleaning Institute says a towel after each use keeps soap scum and hard water from building up on tile. For stone, the Natural Stone Institute names a squeegee.

When it will not work, and what to do instead

A deep clean fixes most showers, but not every problem. Here is what to do when it falls short.

  • There are spots that will not scrub off. On fiberglass, the American Cleaning Institute says an acid-based bathroom cleaner may help with hard water deposits. Keep acids off marble, travertine and limestone. See How to remove hard water stains and limescale.
  • Your stone looks dull or etched. Cleaning will not undo that. The Natural Stone Institute says to call a professional stone restorer for etched areas.
  • The glass doors stay cloudy. Glass needs its own method. See How to clean glass shower doors.

Be safe

  • One cleaner at a time. Rinse one cleaner off completely before any other goes on. Never mix bleach with ammonia, vinegar or any other cleaner. See the full never-mix chart.
  • Air and gloves. Run the fan or open a window and wear gloves the whole time.
  • Read your cleaner’s label for surfaces. The Scrubbing Bubbles Bathroom Grime Fighter label says it is not recommended for acrylic, and to spot test other surfaces first.
  • Natural stone. Keep vinegar, lemon and other acids off it. The Natural Stone Institute says many rust removers and toilet bowl cleaners contain traces of hydrofluoric acid, which attacks all stone.
  • Eyes. The Grime Fighter label says it causes moderate eye irritation. If any gets in your eyes, it says to rinse with water for 15 to 20 minutes.
  • Spray cans. The label says the can is under pressure and may burst above 130 degrees F, and to keep it out of reach of children.

What to buy

We may earn a small fee from these links. It never changes the picks or your price.

  • A tile and grout scrub brush

    Narrow bristles for grout lines and corners. up&up Tile and Grout Scrub Brush was $2.69 at Target.com on 11/7/2026.

  • A foaming bathroom cleaner for tile and fiberglass

    Scrubbing Bubbles Bathroom Grime Fighter aerosol, 20 oz, was $3.79 (regular $3.99) at Target.com on 11/7/2026. Its label says it is not recommended for acrylic, so use it only on surfaces its label names.

  • A shower squeegee

    For the quick wipe after each shower that keeps buildup down. up&up Squeegee with Hanging Hook was $5.49 at Target.com on 11/7/2026.

Why it works

The U.S. Geological Survey explains that the minerals in hard water react with soap and make a scum that clings to shower walls. A cleaner that sits for a bit gives that film time to loosen, so you can wipe it off instead of grinding at it.

The waiting is the part people skip. It is a lot like soaking a dirty casserole dish before you wash it: the soak does the hard part, and the brush only finishes the job.

Maybe you scrubbed for an hour and still saw a cloudy film when the light hit the wall. Most likely the cleaner was not given time to work, or it was the wrong one for that surface.

A word from Denise

So know what your shower is made of, give the right cleaner time to sit, and keep a squeegee on a hook.

Questions people ask

Can I use vinegar to clean my shower?

Not on natural stone. It makes sense to try, since vinegar is an acid and acids can help with mineral spots. But the Natural Stone Institute says vinegar and other acids may dull or etch marble, travertine and limestone. On fiberglass, the American Cleaning Institute says an acid-based cleaner may help with hard water deposits.

What should I not use on an acrylic or fiberglass shower?

Skip scouring powders and scrub pads, which the American Cleaning Institute says can scratch them. Read every cleaner’s label too, because some foaming cleaners say they are not for acrylic.

How often should I clean my shower?

Clorox says regular weekly cleaning helps remove the soap scum and moisture that mold feeds on. A daily shower spray or a squeegee after each shower helps in between.
