Prep first
Before you start
- Let the mud dry, then brush or scrape off as much as you can.
- Rinse what is left with cold water.
- Wait for the mud to dry before you touch it.
Mud dragged into a shower is soil made of fine particles that work into the surface, so it's easiest to lift once it has dried. Wet mud spreads and can work deeper, which is why dry scraping comes first. Pick a gentle cleaner suited to your shower material, and remember that the surface takes cleaners only with care, so rinse as soon as you're done.
Grime from a shower usually needs a second pass, not harder scrubbing. Dirt stains on the shower floor are best worked in small areas at a time so the mess doesn't spread. A white shower pan shows every smear, so check it in good light before you stop.

Step by step
Step 1 of 6
Let the mud dry first
Give the mud time to dry on the surface, since it lifts far more easily once it's firm. Then brush or scrape off as much as you can with a soft brush or plastic scraper. Dried mud comes off in flakes, while wet mud only smears and works deeper.
Careful. Don't rub wet mud in; blot and let it dry first.
Step 2 of 6
Rinse what's left with cold water
Run cold water over the area to flush out the loose grit that's left. Keep rinsing until the water runs clear and the surface feels free of grit.
Careful. Hot water can set this stain, so keep the first rinse cold.
Step 3 of 6
Test before using any cleaner
Choose a hidden spot, such as the underside of the tub lip or a corner behind a fixture. Apply a little of the cleaner you plan to use and check for dulling, color change or roughness before going further.
Step 4 of 6
Wipe with a soft sponge
Dampen a soft sponge or cloth and wipe the mud away in gentle strokes. On vitreous china, use mild soap and warm water instead of anything stronger, and rinse the sponge often so you don't push grit back onto the surface.
Careful. Ammonia cleaners can damage the finish on vitreous china.
Step 5 of 6
Use a cleaner for heavy soil
If dirt is still caked on after wiping, apply a general-purpose cleaner listed for your shower material to the sponge, not straight onto the surface. Work it in lightly and move section by section so the cleaner is never left to sit.
Careful. Don't let cleaners soak on surfaces, and rinse overspray off nearby surfaces.
Step 6 of 6
Rinse and blot dry
Rinse the whole area with plain water right after the cleaner, so no residue is left on the surface. Then blot it dry with a clean cloth and check it from a few angles.

Best products for mud on showers & glass doors
Pick a general-purpose cleaner that is listed for your exact shower material, such as acrylic or vitreous china. Keep abrasive cleansers for set-in marks on enameled cast iron only, and use them sparingly with water.

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
The surface should look even, with no gray film and no gritty feel under your hand. The rinse water should run clear, and the spot should look the same as the area around it.
What changes for yours
Adjust for your showers & glass doors
Dirt on the shower floor
On a shower floor, grit gathers in the low spots and along the drain edge, so spend a little extra time brushing those areas before any water touches them. Once it's loose, rinse with cold water and move to the sponge step. If the floor is cast iron, leave steel wool, wire brushes and abrasive pads out of it.
Work from the outside toward the drain so the rinse water carries the loose dirt away instead of pushing it into the corners.
Dirt on a white shower pan
A white pan shows every gray line, so confirm the material before you pick a cleaner. If it's acrylic, stick to water and a general-purpose cleaner listed for acrylic, with no abrasive cleansers or solvents. Aerosol products are a poor match for acrylic too.
If the pan is vitreous china, use mild soap and warm water and skip ammonia cleaners, which can dull the finish. If you can't tell the material, start with water and a soft sponge, and don't go past that until you know what it is.
Heavy or long-standing buildup
Old mud that has dried and bonded to the surface may need several rounds of treatment before it's fully gone. Start with the steps above and repeat them rather than jumping to stronger products.
For a stubborn mark on enameled cast iron or vitreous china only, a soft abrasive cleaner can be used sparingly and always with water. Work it in with a soft cloth in short strokes, then rinse completely.
If the mark won't come out after a few careful passes, stop rather than trying harsher products. Never use abrasive cleaners without water, and never on acrylic, where they damage the bath surface.

Do home remedies work on mud on showers & glass doors?
Most kitchen and laundry remedies don't belong in a shower, either because they don't lift mud or because the shower surface can't take them. Here is where each one lands for this stain.

What makes it worse
Mistakes to avoid
Don't scrub with steel wool or abrasive pads.
On cast iron, steel wool, wire brushes and abrasive pads are out. On acrylic, abrasive cleansers and solvents damage the bath surface, so a soft sponge and water are the safer tools.
Don't use full-strength bleach or ammonia on acrylic.
Chemically active solutions at full strength can damage an airjet acrylic bath. Keep to water and a mild cleaner, and leave bleach out of these steps.
Don't use harsh cleaners on PVD faucet finishes.
Harsh cleaners can damage PVD faucet finishes. Keep any cleaner off the fixtures and wipe those areas with plain water instead.
Don't mix cleaners in the shower.
Chlorine bleach mixed with ammonia, vinegar or other removers can give off hazardous fumes. If you need a second product, rinse the area thoroughly between them.
When to call a professional
For dull or scratched acrylic, the fix is repair from the manufacturer rather than a stronger cleaner. Enameled cast iron warranties can be voided by improper cleaning, so check the warranty before using anything harsh. If the mud has spread onto the tub itself, the Bathtubs guide covers that surface.
Questions
Why does mud come off more easily after it dries?
Dried mud is loose and comes off in flakes, while wet mud smears and works deeper into the surface. Let it dry, then brush or scrape it off before you rinse with cold water.
Can I use vinegar on grime in my shower?
Not on cement grout or natural stone such as marble, limestone or travertine, where vinegar is unsafe. No, not on cement grout or natural stone such as marble, limestone or travertine, where vinegar is unsafe. Water and a mild cleaner are the better choice.
Is bleach safe to use in a shower?
No. Full-strength bleach isn't safe on an airjet acrylic bath, so use water and a mild cleaner for the whole job. Stick to water and a mild cleaner for the whole job.
What if I don't know what my shower is made of?
Start with water and a soft sponge, and hold off on any cleaner until you know the material. Once you do, test the cleaner on a hidden spot before using it on the visible surface.
Can I use steel wool on the shower floor?
Not if the floor is cast iron, since steel wool, wire brushes and abrasive pads are out on it. Use a soft cloth with water and a general-purpose cleaner listed for your material instead.
Will the cleaner leave a film behind?
It can if it's left to sit, so rinse the area with plain water right after you use any cleaner. Then blot it dry with a clean cloth.
