KitchenAid Washer Rust or Corrosion — Prevention & Repair
Rust appearing on or inside your KitchenAid washer is both a cosmetic concern (particularly on models with the premium PrintShield stainless finish) and a functional one if corrosion reaches structural components or the drum surface where it contacts clothing. Understanding where corrosion develops on KitchenAid machines helps target prevention and repair.
Types of Rust on KitchenAid Washers
External Cabinet/Door Rust
KitchenAid's PrintShield finish provides enhanced fingerprint and scratch resistance but is not immune to corrosion. Chips from impacts expose bare metal underneath. In humid laundry room environments, exposed spots rust quickly. Standard stainless steel cleaners can damage the PrintShield coating — use only KitchenAid-approved cleaners.
Prevention:
- Touch up chips immediately with appliance touch-up paint (match your specific color code).
- Do not use abrasive cleaners, steel wool, or generic stainless sprays on PrintShield surfaces.
- Ventilate your laundry space — Bay Area fog-belt humidity accelerates corrosion.
- Place felt pads between the washer and dryer in stacked configurations to prevent contact wear.
Interior Drum Rust Spots
KitchenAid's satin-finish stainless drum resists rust, but small chips (from buttons, zipper pulls, or metal objects left in pockets) expose raw steel. Rust spots then transfer orange stains to clothing.
Repair:
- Clean the affected area with white vinegar to neutralize existing rust.
- Sand lightly with 400-grit wet/dry sandpaper until bare metal is smooth.
- Apply two-part appliance epoxy (food-safe/water-safe rated).
- Allow 48 hours cure time before running a cycle.
Parts Cost: $10–$20 (epoxy kit) Professional Repair Cost: $100–$175
Rust from Foreign Objects
Rusty screws, nails, or metal pieces left in pockets dissolve during the wash cycle, depositing rust stains inside the drum and on the boot seal. This is not a machine failure — it is contamination.
Solution: Run an empty hot cycle with 2 cups of white vinegar + baking soda to remove staining.
Structural Rust (Outer Tub or Frame)
If the outer plastic tub cracks and exposes the metal frame beneath to water, structural corrosion develops over years. This is rare but irreparable on KitchenAid machines — the frame is integral to the cabinet structure.
Indicators: Rust-colored water dripping from the base (not from clothing), flaking visible under the machine.

PrintShield Stainless Care Guide
| Do | Don't |
|---|---|
| Use mild dish soap + water | Use standard SS cleaner |
| Soft microfiber cloth | Abrasive pads or steel wool |
| Dry immediately after cleaning | Let water spots air-dry |
| Touch up chips within days | Ignore exposed metal |
| KitchenAid affresh SS cleaner | Bleach-based sprays on exterior |
Preventing Rust Stains on Laundry
If your KitchenAid washer is staining clothes with rust:
- Run an empty hot cycle with a commercial rust remover (Iron Out or similar).
- Inspect the drum surface with a flashlight — feel for rough spots.
- Check the back of the drum (visible through rear access) for corrosion on the spider arm (the bracket connecting the drum to the shaft).
- Spider arm corrosion is a known failure mode on front-loaders after 8-12 years — replacement is $150–$300 parts + significant labor.

FAQ
Q: Is rust on my KitchenAid washer drum dangerous for clothing?
Rust is not harmful to health but will permanently stain light-colored fabrics. Address drum rust promptly with epoxy repair to prevent ongoing staining.
Q: My KitchenAid washer's PrintShield finish is peeling. Is this covered under warranty?
Cosmetic coating issues are typically covered only within the first year. After warranty, touch-up paint is the most economical repair.
Q: Can I use CLR or Iron Out inside my KitchenAid washer?
Yes — run an empty hot cycle with the product, then a second empty rinse cycle. These are safe for stainless drums and internal components.
