Prep first
Before you start
- Blot carpet spills with a white cloth, working from the edges toward the center, and don't rub.
- Test any rust remover on a hidden spot before you use it.
- Soaps and detergents won't lift these stains, so don't scrub with them alone.
- Stains keep coming back until the water is treated.
Red, orange or black marks on a sink, tub or tile come from iron and manganese dissolved in well water, which turn colored once they meet air. Soaps and detergents won't lift them, and chlorine bleach can intensify them or set them permanently, so you'll need a dedicated rust product instead. Orange-brown marks point to iron and black ones to manganese, and older marks take more than a quick wipe.
If you're trying to remove iron stains from a sink, check how old the mark is first, since fresh red water stains lift far more easily. Skip vinegar and test a hidden spot with the dedicated rust product first. If the orange keeps returning after cleaning, the well water is feeding it, so call a pro.

Step by step
Step 1 of 5
Test the cleaner on a hidden spot
Start on a hidden spot of the same surface, using only a rust remover made for that surface and following its label. Let the test show whether the finish holds up before you treat the full stain.
Tip. Use a spot that's out of sight, like the back edge of a sink.
Careful. Oxalic acid is poisonous, so wear rubber gloves and keep it off your skin.
Step 2 of 5
Apply the rust remover to the stain
Apply it only to the stain, working in small areas so you can watch it lift. Keep the area wet with the remover until the stain is gone, and follow the label for timing.
Careful. Don't let rust removers splash porcelain or enamel appliance finishes; they can ruin the finish.
Step 3 of 5
Rinse the surface completely
Rinse the area thoroughly with clean water before you do anything else. Any remover left on the surface can end up mixing with the next product you reach for, so clear it fully.
Careful. Don't mix a rust remover with bleach or other household cleaners.
Step 4 of 5
Check the stain and repeat if needed
Let the surface dry, then look at the stain in good light. If you can still see rust, repeat the treatment and rinse again, and stop once it's gone.
Tip. Check in daylight or a bright light, since faint rust is easy to miss.
Step 5 of 5
Treat the water so stains stop returning
Stains keep coming back until the water is treated, so have the well water tested by a certified lab. Choose a treatment system based on the results, and keep up with it.

Best products for iron
Look for a rust remover labeled for the surface you're cleaning, and follow its label for how long it stays on.
Amazon Basics Microfiber Cleaning Cloths
How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on these surfaces, 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 →Pick what it is on
Iron on every material
No match. Try the main search for anything else.
How to tell it's working
Look for the stain to fade and lose its edge as the remover works. If it's gone after the first rinse, you're done, and a faint shadow that remains means one more round.
What changes for yours
Adjust for where the stain is
Flat irons
The plate of a flat iron is a different surface from the ones in these steps, so the rust remover here isn't a safe fit. Unplug the iron and let it cool completely, then check the maker's manual or ask the manufacturer before you put any rust remover on it.
If the stain is on a garment instead, treat the fabric by its care label and see the Clothes guide for the details. Don't test any cleaner on a hot plate.
Vinyl siding and outdoor surfaces
Pretest in a small area and let it dry before treating the whole surface. Mix 1 cup of powdered rust remover into 1 gallon of warm water in an open container, wet the surface with clear water, and apply the mix from the bottom up with a brush or sponge. Keep it saturated until the stains are gone, then rinse promptly and thoroughly, including any overspray on plants and lawn.
Don't use it on paint, painted siding, wood, exposed metal or glass. For the siding itself, see the Siding guide.
Heavy or long-standing buildup
Old stains need more time than fresh ones, so plan on a second round rather than a harder scrub. On boil-safe white cotton or linen, boiling in 4 teaspoons cream of tartar per pint of water can lift a stain that has already set, and you can repeat it until the stain is gone.
A stain that has dried into ceramic tile may need an oxalic acid poultice, with the gloves kept on the whole time. On washable items, repeat the rust remover per its directions before you try anything stronger.
Some stains won't come out completely, especially while the water is still rusting. That's a water problem, so a lighter stain is a realistic goal until the water is treated.

What makes it worse
Mistakes to avoid
Don't use chlorine bleach on iron or rust stains
Chlorine bleach can intensify or permanently set these stains, so a stain that looked fixable can end up permanent. Reach for the rust remover instead, and keep chlorine bleach away from the stain.
Don't use a lime-and-rust cleaner on clothing or stone
Strong lime-and-rust cleaners aren't safe on clothing, carpet, natural stone, wood, or painted or coated surfaces. Check the label before you use one anywhere, and choose a rust remover made for the surface instead.
Don't dry a stained item before it's clear
Heat can set a stain that's only partly gone, so keep the item out of the dryer until you can't see any rust. If the stain is still there after the item air dries, repeat the treatment before you try again.
Don't leave a rust remover on past its label
Longer exposure can damage the surface, and on dark surfaces a remover that isn't rinsed promptly can leave a white residue. Rinse on time, then check whether the stain has lifted.
When to call a professional
If the lab results are hard to read, a water treatment professional can explain what they mean and recommend a system to match. Until the water is treated, expect to repeat the rust treatment now and then.
Questions
Does vinegar remove iron stains?
No, skip vinegar. Use a rust remover made for the surface you're cleaning, test it on a hidden spot, and follow its label.
Why does my well water leave yellow stains?
Well water that runs clear and then leaves marks is picking up dissolved iron or manganese from the rock it has passed through. Iron usually shows as orange-brown and manganese as dark gray to black, so a yellow mark doesn't tell you much on its own. Get the water tested by a certified lab to find out what's in it.
Does iron stain?
Yes. Iron in well water leaves reddish-brown or orange-brown stains on laundry, sinks, toilets and tubs, while manganese leaves dark gray-to-black ones. Both come from the rock the water passes through, so the water test matters either way.
What's the difference between iron and manganese stains?
Iron stains are reddish-brown or orange-brown, and manganese stains are dark gray to black. Both come from dissolved minerals in well water that darken once they meet air. The water test tells you which one you're dealing with.
Is sodium bisulfate a good choice for iron stains?
We don't have directions for sodium bisulfate, so we can't recommend it for iron stains. Check its label for the surfaces it's rated for before you buy or use it, and stick with a rust remover made for your surface in the meantime.
How long does it take to remove an iron stain?
It depends on the surface and how old the stain is, but a fresh stain on washable white laundry usually needs a soak of 10 to 15 minutes. Rust removers follow their own label for timing, so check it before you start.
