Prep first
Before you start
- Work out whether the mark is hard orange-brown iron or a slimy pink-red film before you use anything.
- Pretest any remover on a hidden spot, because rust removers are strong acids and dye removers can strip color.
- Keep rubber gloves on when you handle a rust remover or any acid.
- Rinse the area with clean water when you finish, so no cleaner is left on the surface.
Orange-brown marks in a shower usually come from iron in the water or from nearby metal that's rusting, and the iron oxidizes as it meets air. Pink-red slime is a different problem, caused by bacteria that keep coming back unless you scrub them away. Acrylic and cast iron have their own limits, so the surface under the stain limits how hard you can scrub.
Pink stains in the shower lift best with steady, consistent scrubbing, and a scouring cleanser is the product to compare for that job. Orange stains in the shower on acrylic need a lighter touch, so test a hidden corner first. Keep going only while the color is still lifting, and stop once it stops changing.

5 steps
Step by step
Step 1 of 5
Identify the stain before treating it
Orange to reddish-brown marks that feel hard are usually iron from the water or from rusting metal. Pink-red film that is slimy is usually a bacterium, and blue-green marks on fixtures come from copper dissolved by corrosive water.
Pretest any remover on a hidden spot before you use it on the visible stain.
Careful. Chlorine bleach sets and intensifies iron stains, so keep it off orange or brown marks until you know they are not iron.
Step 2 of 5
Scrub the film with a brush
Scrub the spots where soap scum, fatty residue and bacteria collect, using a brush and household cleanser on tile, grout and glass. On acrylic, use mild soap and warm water with a soft cloth instead, since abrasive cleansers damage it.
Tip. Work the brush into grout lines and corners, where the film gathers first.
Careful. Don't scratch fixtures with abrasives; scratches make them more open to the bacteria.
Step 3 of 5
Rinse the cleaner away completely
Rinse the whole area with clean water so no cleaner is left on the surface. Rinse overspray off nearby surfaces too, such as the glass and the walls beside the tub.
Careful. Don't let cleaners soak on the surface; rinse them off as soon as the scrub is done.
Step 4 of 5
Dry the surface and check the color
Wipe the surface dry with a soft cloth. If orange or brown color is still visible, it is iron and needs a rust remover rather than bleach, so leave the bleach step off that spot.
Step 5 of 510 to 20 minutes
Disinfect the slime with bleach
On tile and grout, apply a strong chlorine bleach solution to the pink-red slime and leave it on for 10 to 20 minutes. Rinse thoroughly with clean water afterward, and skip this step on acrylic and airjet baths.
Careful. Never mix chlorine bleach with acidic rust or toilet cleaners, vinegar or lemon juice, because it releases chlorine gas.

How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on showers & glass doors, and its directions fit the steps above.
Finished the steps? How does it look?
Nice work. Let it dry completely and check it again in good light. Here is what done looks like:
How to tell it's really gone →A faint mark usually needs one more round, not a stronger product.
Heavy buildup usually takes more than one round.
Heavy or long-standing buildup →When to call a professional →How to tell it's working
A slime stain that is gone leaves an even surface with no pink film when you wipe it with a damp cloth. If an orange-brown mark is still there after rinsing and drying, it is iron, and a rust remover is the next step.
What changes for yours
Adjust for your showers & glass doors
Pink on the Shower Floor
Pink film on a shower floor follows the same route as the wall slime, but the floor collects more soap, fatty residue and standing water. Give the floor and the drain area extra time in the scrub step, and make sure the floor is fully dry afterward.
Keep the bleach step for tile and grout on the floor, and rinse thoroughly so no residue sits on the surface. If the pink keeps coming back, the floor is being left damp, so dry it more thoroughly after each use.
Acrylic
Acrylic changes the routine more than any other surface. Skip the bleach step, and use mild soap and warm water with a soft cloth for the whole job.
Do not use solvents or aerosol cleaners on it, and don't reach for abrasive cleansers even on a stubborn mark. Dull or scratched acrylic needs the manufacturer, not more scrubbing.
Cast Iron
Cast iron takes a rust remover or muriatic acid for occasional rust, and it is the one surface where an abrasive cleaner can be used, and only sparingly. Keep steel wool, wire brushes, abrasive pads and solvents away from it.
Rinse the surface fully after any rust treatment and dry it with a soft cloth. Give any rust remover a pretest on a hidden spot first, since rust removers are strong acids.
Vitreous China
Vitreous china gets mild soap and warm water for routine cleaning, and the scrub uses a soft brush rather than a gritty one. Strong abrasive cleansers scratch and dull this surface, so skip them.
Rinse thoroughly and dry the surface with a soft cloth so no film is left to collect. Mild soap is the only cleaner this surface needs for everyday care.
PVD Faucets
PVD faucet finishes take mild soap and warm water with a soft cloth, and they need no bleach step. Rinse and dry them after each scrub so the finish stays clear of residue.
Keep the faucet out of the bleach step even when the tile around it gets the treatment. Rinse overspray off the faucet as you scrub the tile next to it.
Heavy or long-standing buildup
Old orange marks that have dried into grout or the tub can be stubborn, and the first steps may only lighten them. Dried iron usually needs a rust remover made for the material, which is a strong acid. Pretest it on a hidden spot before you use it.
Wear rubber gloves for the whole job, because rust removers are strong acids and oxalic acid is poisonous. On enameled cast iron, muriatic acid is the other option for occasional rust, and it follows the same gloves and pretest rules. Rinse the area well when the rust treatment is finished, then dry it.
Pink-red slime that comes back after a treatment means the bacteria are still there, so keep scrubbing and disinfecting on a regular schedule. Stains that stay after several tries may be set into the surface and won't fully lift. Dull or scratched acrylic is a repair job, not a cleaning job.

What makes it worse
Mistakes to avoid
Don't use abrasives or solvents on acrylic
Abrasive cleansers, solvents and aerosol cleaners damage the bath surface. Stick to mild soap, warm water and a soft cloth, and skip anything gritty.
Don't use ammonia on your fixtures
Ammonia can damage the finish on vitreous china, and full-strength ammonia can't go in airjet acrylic baths. Mild soap and water are the safe choice on those fixtures.
Don't use harsh cleaners on PVD faucets
Never use ammonia, bleach or acid on the finish, since they can damage it, even on a stubborn mark. Wipe the faucet with mild soap and water and a soft cloth instead.
When to call a professional
For dull or scratched acrylic, contact the manufacturer's customer service for repairs. Improper care and cleaning can void a cast iron warranty, so check the terms before you try a stronger rust treatment.
Questions
How do I stop orange stains from coming back?
Rinse and dry the shower after each use with a soft cloth. Remove rusting metal items from the shower, since they are a common source. If your water carries iron, the regular wipe-down matters most.
What causes orange stains in the shower?
Orange to reddish-brown stains are most often iron, or rust, from the water or from rusting metal. Iron oxidizes when it meets air, which is why the stain can set and get harder to lift.
Where does the pink slime in a shower come from?
Pink-red slime is usually the bacterium Serratia marcescens, which grows in bathrooms. It forms a soft, slimy film where soap residue and fatty build-up collect. Scrubbing and disinfecting clear it, and keeping surfaces dry helps keep it from returning.
Why does my shower get red stains?
Red describes a color, not one substance, so the texture tells you the cause. A slimy red or pink film is usually the bacterium, while a hard red-brown mark is usually iron. Check which one you have before you use bleach or any remover.
Do I need a rust remover for an orange stain?
Only if the stain is still there after you've rinsed and dried it. Rust removers are strong acids, so pretest one on a hidden spot and wear rubber gloves while you use it.
Can I clean a red dye stain from a shower tub?
Pretest any dye remover on a hidden spot first, since dye removers can strip color. If the tub is acrylic, stick to mild soap and water, and skip abrasive cleansers and solvents.
