Quick answer

Why is your tile grout turning white? It is usually efflorescence (mineral salts that moisture pushes to the surface), leftover cement haze, or hard-water scale, and sometimes acid cleaners have stripped the color. Dry-brush the powder, rinse, and try a diluted vinegar wipe on cement grout with ceramic or porcelain tile. If the white film stays, a grout haze remover dissolves it, and a grout colorant can restore faded color.

Free fix vs. permanent fix

Free fix · 30 minutes

Dry-brush, rinse, and a diluted vinegar wipe

  • Dry-brush the white powder with a stiff nylon brush and vacuum it up
  • Wipe with a damp cloth and rinse with clean water
  • On cement grout and ceramic or porcelain, try half vinegar, half water, then rinse
  • Dry the area and look for where moisture is coming from

How long it lasts: Months if the cause was light hard-water scale. Efflorescence returns while moisture keeps moving through the grout.

A grout haze remover

A haze remover dissolves the cement and mineral film that water and vinegar leave behind, so the grout color shows again. Vinegar is mild and stops working on thick haze. A haze remover is built for it. Use it once, rinse well, and the stuck-on white is gone.

What to get: Grout haze remover

How long it lasts: Often permanent for the haze it removes. Fix the moisture source, or the white will come back.

Why it happens

1

Efflorescence

Water moving through cement grout carries dissolved salts to the surface. The water evaporates and leaves a white, powdery crust behind. It is common on new installs and on grout near leaks or a damp slab.

2

Leftover cement haze

After tile is installed, a thin film of cement can stay on the tile and grout. It dries white and gets harder to remove the longer it sits.

3

Hard-water scale

In showers, around sinks, and on kitchen backsplashes, hard water leaves calcium and lime. It builds up on grout as a crusty white film.

4

Etched or bleached grout

Acidic cleaners, strong bleach, and harsh scrubbing can strip the surface of colored grout and leave it looking white and chalky.

5

Sealer or soap residue

Too much sealer, or a soap film that was never rinsed, can cloud the grout lines and leave a white bloom.

Try this first (free)

Do these in order, starting with the simplest.

  1. Test a small spot

    Rub a dry cloth over the white. If a powder comes off, it is likely efflorescence. If it feels like a hard film, it is haze or scale. If the grout just looks pale and rough, it may be etched.

  2. Dry-brush and vacuum

    Tool used: Stiff nylon brush

    With the grout dry, scrub the white with a stiff nylon brush and vacuum up the powder. Do not use a wire brush, which will scratch the tile and scar the grout.

  3. Wipe and rinse

    Tool used: Microfiber cloths

    Wipe with a damp microfiber cloth and rinse with clean water. That removes loose salts. Dry the area with a clean towel.

  4. Try diluted vinegar on cement grout, not natural stone

    Tool used: White vinegar

    On ceramic or porcelain tile with cement grout, spray equal parts vinegar and water, wait 2 to 3 minutes, scrub, and rinse well. Skip it on marble, travertine, limestone, and polished tile. Never mix vinegar with bleach.

  5. Use a haze remover on the stubborn white

    Tool used: Grout haze remover

    Wear gloves and eye protection and ventilate the room. Test a small spot first, apply as the label says, scrub, then rinse several times with clean water. Wait until the grout is dry before you seal it.

When free fixes aren't enough

If the white returns within a few weeks of cleaning, moisture is still moving through the grout. Look for a leak behind or under the tile, a damp slab, or a splash zone with no ventilation. No cleaner fixes a leak. If the grout is crumbling or cracked, regrout the area. If it looks faded or chalky after cleaning, the color has been stripped, and a colorant or new grout is the next step. If the white growth smells musty or sits near a leak, it may be mold, so treat it as mold instead.

How we picked: How we picked: this page is based on tile and grout care guides, haze remover instructions from the makers, and the problems and fixes people report in reviews. We do not test products by hand.

Which kind of white is it?

  • Dry powder that brushes off: efflorescence. Moisture is moving through the grout.
  • A hard film on the tile and grout after an install: cement haze.
  • A crust near faucets and shower walls: hard-water scale.
  • Pale, rough grout with no film: etched or faded color.

Seal it after, and keep it dry

Once the grout is clean and fully dry, a penetrating sealer slows moisture moving through it. Run the exhaust fan or open a window after showers, and fix drips at the source. Keeping grout dry is the best way to stop the white from coming back.

What to skip

Bleach and strong acid cleaners on colored grout

Bleach and strong acids can strip color and etch the surface, which makes grout look whiter and chalkier, and they can damage natural stone. If the label does not list your tile and grout type as safe, leave it on the shelf.

Frequently asked questions

Why is my tile grout turning white?
Most often efflorescence, leftover cement haze, or hard-water scale. Acid cleaners and bleach can also strip color. A dry cloth helps tell which: a powder is salts, and a hard film is haze or scale.
Is white powder on grout mold?
Usually not. Efflorescence is dry and chalky and brushes off. Mold is fuzzy or spotty, often gray, green, or black, and smells musty. If the area stays damp or smells, treat it as mold.
Will the white come back after I clean it?
It will if moisture keeps moving through the grout. Cleaning removes the white, not the cause. Fixing leaks, ventilating, and sealing after cleaning slow the return.
Can I use vinegar on grout every week?
Occasional diluted vinegar is fine on cement grout. Acid slowly wears grout and can fade the color, so use it sparingly, rinse well, and switch to a pH-neutral cleaner for upkeep.
