Why Is My Washer Leaving Rust Stains on Clothes?

If your washing machine is leaving orange or brown rust stains on your clothes, the most likely culprits are a rusting drum, corroded agitator fins, deteriorating metal components inside the tub, or rust in your home’s water supply. In most cases, the problem is fixable — but catching it early matters before expensive repairs or ruined clothes pile up.

Rust stains on freshly washed laundry are one of the more frustrating washing machine problems homeowners in Grand Rapids, Kalamazoo, and Lansing deal with. Let’s walk through exactly what causes it and how to figure out which problem you’re facing.

The Most Common Causes of Rust Stains from a Washer

1. Rust Inside the Drum or Tub

The washing machine drum is typically made of stainless steel or porcelain-coated steel. Over time — especially if the porcelain coating chips — the exposed steel underneath begins to corrode. Water and detergent accelerate the process.

You can usually spot this with a flashlight: look for brown streaks, flaking paint, or rough patches on the interior drum walls. Run your hand along the inside carefully. If you feel rough, scaly spots, rust has formed on the tub itself.

This is one of the most common causes, especially in older machines or washers that have had small metal objects (coins, bobby pins, bra underwires) bang around inside.

2. A Corroded or Rusting Agitator

Top-load washers with agitators have moving plastic and metal parts. The agitator shaft and base can corrode over time, especially if water pools around the base of the agitator between cycles. The rust migrates onto clothes during the wash.

Inspect the base of the agitator where it meets the tub floor. If you see rust-colored residue or corrosion at the seam, the agitator components may need to be cleaned, treated, or replaced.

3. Deteriorating Drum Spider or Outer Tub

Front-load washers have a component called the drum spider — a metal arm assembly that supports the drum on the back bearing. On some models, particularly certain LG and Samsung front-loaders, the spider arm is made of aluminum that can corrode and shed rust-colored residue over time, even without being iron-based rust.

This repair is more complex and typically requires a technician, as the drum has to come apart.

4. Rust in Your Home’s Water Supply

This one is easy to overlook: sometimes the washing machine isn’t the problem at all — your water is. Michigan has many homes with older iron pipes, and if your water supply has elevated iron content, rusty deposits will show up in the wash.

To test this, fill a clear glass with cold tap water from the laundry room. If you notice any brown or orange tint after letting it sit for a few minutes, iron in the water supply may be the culprit. Grand Rapids area homeowners with older homes or private wells sometimes encounter this seasonally, especially after heavy rains disturb sediment in lines.

A whole-home water filter or iron filter can resolve this without any washer repair needed.

5. Foreign Metal Objects Left in the Drum

This one is simple but common: metal items left in pockets — coins, keys, screws — can rust and stain the drum and your clothing. A single metal button or forgotten hardware can corrode quickly once wet and heated.

Always check pockets before loading laundry. If you suspect this is the cause, look for individual rust spots on clothes rather than uniform staining across multiple items.

6. Rust on Washer Components (Springs, Counterweights, Hoses)

Inside both top-load and front-load washers are various metal support components — springs, counterweights, brackets, and clamps. If the outer tub develops a crack or a water leak, moisture can reach these metal parts and cause rust that eventually migrates into the wash water.

This is harder to diagnose without opening the machine but is often accompanied by other symptoms: loud banging sounds, vibration, or visible water pooling under the washer.

How to Identify Which Problem You Have

Here’s a simple diagnostic approach:

Step 1: Check your water. Fill a clear glass and look for discoloration.

Step 2: Inspect the drum interior with a flashlight. Look for rough patches, chips in the porcelain, or visible rust streaks.

Step 3: Check the agitator (top-loaders) for corrosion at the base.

Step 4: Look at the staining pattern on clothes. Uniform brown staining on many items suggests water supply or drum rust. Isolated spots suggest foreign objects.

Step 5: Check under the washer for any water pooling, which might suggest a cracked outer tub leading to internal rust.

Can You Fix Rust in a Washing Machine Drum Yourself?

Minor rust spots on the interior drum can sometimes be treated with an appliance-safe porcelain repair kit. These kits fill in chips and seal the exposed metal. They work reasonably well for small areas, but they’re a temporary fix — not a permanent solution.

For larger corroded areas, or if the drum has significant damage, the drum itself may need to be replaced. Depending on the machine’s age and the cost of a new drum, it may be more economical to replace the washer entirely. See our guide on when appliance repair costs more than a new machine for a general cost framework.

What you should NOT do: Don’t sand the drum or use wire brushes — this creates sharp edges that will tear clothes and can embed metal particles in the drum that cause further problems.

What About Rust Stains Already on Clothes?

Getting rust stains out of laundry requires acting before heat sets the stain. Heat — especially from a dryer — permanently bonds rust to fabric.

For fresh rust stains:

• Apply a commercial rust remover (like Iron Out or Bar Keeper’s Friend — use fabric-safe versions)
• Lemon juice and salt is a natural option: apply, let sit in sunlight for 30 minutes, rinse
• White vinegar applied directly before washing can help lift the stain

Do not use chlorine bleach. Bleach reacts with rust and actually sets the stain worse.

Once you’ve treated the stain, wash in cold water without a dryer until you’ve confirmed the stain is fully removed.

When to Call a Professional

You should call a repair technician if:

• You find visible rust inside the drum that covers more than a small patch
• The drum has chips or cracked porcelain coating in multiple areas
• You’re hearing new banging, grinding, or vibration noises alongside the rust stains
• A front-load washer is showing rust symptoms (drum spider repairs are not DIY-friendly)
• The rust started suddenly after noticing water under the machine

Catching drum or internal component rust early can save you hundreds of dollars. Left unchecked, corroded internals can destroy bearings, seals, and eventually the motor — turning a $150 drum patch into a $600+ repair or a full replacement.

How Michigan’s Hard Water Affects Rust Formation

West Michigan has notoriously hard water. While hardness itself (calcium and magnesium) doesn’t cause rust directly, it does leave mineral scale buildup on internal components. That scale can trap moisture in crevices, accelerating the corrosion of any exposed metal — including drum chips, springs, and brackets.

Running a cleaning cycle with a washing machine cleaner tablet (Affresh, Tide Washing Machine Cleaner) monthly helps remove mineral buildup and extend the life of metal parts.
