Quick answer

To get rid of pink mold in the shower, wipe it off with a diluted bleach spray or a vinegar spray, scrub the corners and caulk lines, then rinse and dry. The pink slime is usually bacteria, not true mold, and it grows wherever soap film stays damp. A daily shower spray after the last shower of the day keeps it from regrowing.

Free fix vs. permanent fix

Free fix · 15 minutes

Wipe with a diluted bleach or vinegar spray

  • Wear gloves and open a window or run the fan
  • Spray, wait 5 to 10 minutes and scrub
  • Rinse well and dry the surfaces
  • Never mix bleach with vinegar or any other cleaner

A daily shower cleaner spray

Pink slime lives on soap film and dampness. A daily spray takes about ten seconds and keeps the film from building, so you stop scrubbing every week. It helps only if you use it, and it does not cut humidity.

What to get: Daily shower cleaner spray

How long it lasts: As long as you spray after the last shower of the day. It stops soap film from building up, so there is less to grow on.

Why it happens

1

Bacteria, not mold

The pink or orange slime is usually a bacterium called Serratia marcescens. It feeds on soap and shampoo residue and thrives in damp spots.

2

Soap film on every surface

Bar soap, body wash and shampoo leave a thin film on tile, tub, caulk and the curtain hem. That film is the food.

3

Damp that never dries

A weak fan, a closed door and a bunched shower curtain keep surfaces wet for hours. Slime needs only a damp corner.

4

Spread by sponges and bottles

A wet loofah, a soap dish and the bases of shampoo bottles hold water and film. They carry the slime from spot to spot.

Do these in order, starting with the simplest.

  1. Ventilate and glove up

    Tool used: Rubber gloves

    Open a window or run the fan, and put on gloves. Never mix bleach with vinegar, ammonia or other cleaners, because that can release dangerous gas.

  2. Mix one cleaning spray

    Tool used: Spray bottle

    Use 1 part household bleach to about 10 parts cool water, roughly 1 cup per gallon. On colored grout, caulk or natural stone, use white vinegar instead, or 3% hydrogen peroxide, since bleach can fade them.

  3. Spray, wait and scrub

    Tool used: Stiff grout brush

    Spray all pink areas and wait 5 to 10 minutes. Scrub the corners, caulk lines, the curtain hem and the soap dish.

  4. Rinse and dry

    Rinse until you no longer smell bleach or vinegar. Dry with a towel or squeegee and leave the fan on for 20 minutes.

  5. Wash or replace the sponges and the curtain

    Machine-wash a fabric curtain liner per its label, or replace a slimy plastic one. Swap an old loofah and rinse the soap dish.

  6. Spray daily after the last shower

    Tool used: Daily shower cleaner spray

    Mist the walls, tub, caulk and curtain with a daily shower spray. Check the label to see whether you can leave it on.

When free fixes aren't enough

If the pink returns within a week, the free fix removed the slime but not what feeds it. A daily spray covers the soap-film side, and a squeegee and fan deal with the dampness. If you see black, green or fuzzy growth, the grout is crumbling, the patch is bigger than about 10 square feet or there is a musty smell from inside a wall, treat it as mold and consider a pro. If someone at home has a weakened immune system or breathing problems, have someone else do the cleaning.

Daily shower cleaner spray

Fixes: pink film regrowing on soap scum

Look for: Labeled safe for your tub, tile, glass and grout; A leave-on formula you spray after the last shower; Label wording about soap scum or mildew prevention; A fragrance you can live with in a steamy room.

Who it's for
Households that shower daily and do not want to scrub every weekend.
Honest downside
Your shower is natural stone, which needs its own cleaner, or you are sensitive to scents. Never mix it with bleach.

Why is my bathtub turning pink, and why are my bathroom tiles turning pink?

If your bathtub is turning pink or your bathroom tiles are turning pink, you are looking at the same slime. It starts at the lowest, dampest spots: the tub edge, grout lines and corners. It then spreads upward along the soap film. If the color is orange or rust and gritty, check for rust or iron in the water instead.

Where pink slime hides

  • The bottom hem of the shower curtain and liner
  • Caulk lines and corners, where water sits
  • The soap dish and shampoo bottle bases
  • The drain edge and the toilet bowl waterline

What to skip

Mixing bleach and vinegar for extra power

Together they release chlorine gas, which is dangerous to breathe. Use one product at a time, rinse well between products and keep the room ventilated.

Frequently asked questions

How to get rid of pink mold in bathroom areas outside the shower?
The same wipe works on the toilet bowl waterline, sink drain, soap dishes and the sink's base. Spray, wait, scrub, rinse and dry. To get rid of pink mold for good, remove the film and the damp.
Why does my bathtub turn pink?
Soap and shampoo residue in a damp tub feeds pink bacteria. Slow draining and standing water make it worse. Wipe the tub dry after each use.
Is pink mold dangerous?
For most healthy people it is a nuisance. People with weakened immune systems, or anyone with an open cut, should avoid contact and let someone else clean it.
Can I use vinegar instead of bleach?
Yes, on most surfaces. White vinegar removes the slime, but avoid it on natural stone, where acid can damage the finish. Always rinse between products.
