How to Remove Washing Machine Rust Stains Like a Pro

Let’s Talk Rust: The Washing Machine’s Not-So-Glamourous Guest

Rust stains on your washing machine might seem like a rare tragedy, but they’re more common than you’d think—thanks to water minerals, metal parts, and the occasional overenthusiastic detergent spill. And let’s be honest, dealing with rusty smudges is about as fun as doing laundry on a Monday morning.

But fear not. You don’t have to call in the appliance exorcist just yet. With a few clever hacks and some elbow grease, your washing machine can look rust-free—and maybe even impress your laundry room visitors. Ready to roll up your sleeves? We’ve got you covered.

Why Does Your Washing Machine Get Rust Stains?

Before we jump into scrubbing and spraying, let’s get curious about why rusts shows up in the first place. Rust stains mostly come from iron particles mixing into your water supply — yep, even tap water isn’t immune (source).

Once these iron particles encounter moisture and air inside your machine, hello oxidation—and you get rust. Additionally, washing machines, especially older models, have metal parts that can start corroding internally, leaking rust particles directly into your laundry or machine surfaces.

So yes, rust stains aren’t just eyesores—they’re little signs telling you, “Hey, some maintenance is overdue here!”

Step 1: Gather Your Rust-Busting Armory

Here’s what you’ll want handy before the battle begins:

  • Commercial rust remover (like CLR Calcium, Lime & Rust Remover) — tested and trusted (source)
  • Baking soda
  • White vinegar
  • Salt
  • Clean cloths or soft-bristle brush
  • Rubber gloves (optional, but your skin will thank you)
  • Water spray bottle
  • A screwdriver or wire brush for manual rust removal (if needed)

Step 2: Removing Rust Stains From Your Washing Machine

There are a couple of approaches based on how stubborn your rust stains are and which type of washing machine you have. We’ll break it down easy-peasy.

2.1 The CLR Method: When You Want Professional-Level Results

For top-loading machines, here’s a neat trick recommended by cleaning pros:

  1. Start the washing machine and let it get to the main wash cycle but pause it before agitation begins.
  2. Add 1/2 cup of CLR directly into the water.
  3. Resume the cycle and let it finish.
  4. Run one more wash cycle with only clean water to rinse any residue inside.

For front-loading and high-efficiency machines, add half a cup of CLR to the detergent drawer during a regular wash cycle. For high-efficiency models, a quarter cup usually does the trick (source).

2.2 The Baking Soda and Vinegar Paste: The Classic Home Remedy

Prefer a natural approach? Baking soda paired with vinegar is your dynamic duo.

  • Mix baking soda with enough water to form a thick paste.
  • Apply the paste on rust stains directly.
  • Spray or dab some white vinegar over the paste—you’ll see it fizz, which is the rust getting a one-two punch.
  • Let it sit for 30 minutes. Use a gentle brush or clean cloth to scrub in circular motions.
  • Rinse away with water and wipe the area dry.

Repeat if necessary, but usually this does a solid job without any harsh chemicals.

2.3 Manual Rust Removal: When It Gets Serious

If you’ve spotted actual corrosion or rust flakes inside your washing machine, manual intervention might be necessary:

  • Use a screwdriver or wire brush to gently scrape away loose rust spots.
  • Afterward, apply a waterproof silicone sealant or rust inhibitor to affected metal areas to prevent recurrence.
  • For safety, make sure to unplug your machine and handle metal parts carefully to avoid damage.

This approach is especially useful if you want to avoid frequent rust stains and keep your washing machine’s insides in tip-top shape.

Step 3: Rust Stains on Clothes? Handle Those Separately

If rust stains have crept from your machine onto your favorite shirts or socks, here are three friendly yet effective fixes:

  • Commercial Rust Remover for Fabrics: Products like those recommended by Clorox are formulated to lift rust safely off fabric. Follow instructions and avoid bleach, which can darken stains.
  • Vinegar and Salt: Create a paste with equal parts salt and white vinegar. Apply on the stain, let it sit for 30 minutes, then gently scrub and rinse in cold water.
  • Baking Soda Paste: Similar to the machine cleaning method: baking soda + water paste, applied to the rust spot, scrubbed and rinsed thoroughly.

Always wash the fabric afterward in cold water, and avoid drying until the stain is completely gone, or it may set permanently.

Preventing Rust Stains: Because Prevention > Scrubbing

You feel me—nobody wants to be stuck scrubbing rust stains in the first place. Prevention is your best friend:

  • Use a Water Softener or Filter: Lowering iron content in your water can drastically cut down on rust.
  • Check and Replace Rusting Parts: Regularly inspect internal metal parts. If any are developing rust, swap them before they mess up your entire wash.
  • Keep the Washing Machine Dry: Leave the door or lid open after washes to reduce moisture-related rusting inside.
  • Clean Your Washing Machine Regularly: Running monthly cleaning cycles with vinegar or commercial washing machine cleaners keeps rust and residue at bay (source).

Like any grumpy household guest, rust hates being ignored. Regular attention keeps it from throwing a rusty tantrum in your laundry area.

Bonus Pro Tips and Tricks

  • If your washing machine bleach tray is a rust hotspot, cleaning or replacing it can stop stain transfer (see this rust repair video).
  • For persistent rust in hard-to-reach places like washing machine pipes, consider specialized internal cleaning or replacement (How to Remove Washing Machine Pipe Without Tears).
  • When in doubt, consult the washing machine manual or a professional—some modern machines have sensitive parts that require specific rust treatment.
