Yes — some stainless steel pegs can rust over time, particularly cheaper pegs made from lower quality stainless steel. However, good quality stainless steel pegs — especially 304 and marine grade 316 stainless steel — are designed to resist corrosion and can last for many years outdoors, even in challenging conditions.
Quality stainless steel pegs are one of the longest-lasting and lowest-maintenance options for outdoor laundry.
Unlike plastic pegs that can become brittle and crack in the sun, stainless steel pegs can handle years of outdoor weather exposure with very little upkeep.
However, not all stainless steel pegs are made equally, and the type of stainless steel used can make a significant difference to how well they resist rust over time.
Why do stainless steel pegs rust?
Despite the name, stainless steel is not completely stain-proof.
Stainless steel is made primarily from iron and carbon, with chromium added to help create a protective surface layer that resists corrosion. Many stainless steel products also contain nickel and other alloying elements to further improve corrosion resistance.
When this protective layer is damaged, exposed to harsh conditions, or made with lower levels of chromium and nickel, corrosion can still occur over time.
This is why some cheap “stainless steel” pegs may still rust outdoors — particularly in coastal or humid environments.
Salt, moisture and humidity all accelerate corrosion.
Why do some stainless steel pegs rust faster than others?
Not all stainless steel pegs are made the same.
Some cheaper pegs use:
- lower quality stainless steel
- thinner wire
- lower chromium and nickel content
- reduced corrosion resistance
This can lead to:
- rust spots
- tarnishing
- weaker grip
- marks on clothing
No one wants rust marks on their washing.
Cheaper pegs can sometimes look similar at first, but differences in stainless steel quality often become noticeable after months or years outdoors.
At Biome, our stainless steel pegs are tested to confirm the claimed grade of steel, which is especially important for products designed to live outdoors year-round.
If you have ever wondered why some metal pegs last beautifully for years while others quickly tarnish or rust, the quality of the stainless steel is usually the reason.
The type of stainless steel used can make a big difference to how well pegs handle moisture, salty air and long-term outdoor use.
What is the difference between 201, 304 and 316 stainless steel?
201 stainless steel
201 stainless steel is a more affordable grade suitable for many everyday environments.
It performs well for general household laundry and is a good option for many homes away from harsh coastal conditions.
304 stainless steel
304 stainless steel offers higher corrosion resistance and is commonly used for kitchenware, wet environments and outdoor products.
It is a durable choice for many Australian households.
316 marine grade stainless steel
316 stainless steel is the most corrosion-resistant option and is often referred to as marine grade stainless steel.
316 stainless steel contains molybdenum, which helps improve corrosion resistance in salty and coastal environments.
It is the best choice for:
- coastal homes
- salty air
- humid climates
- pegs left outdoors permanently
If you live near the beach, this is generally the safest long-term option.
Can you leave stainless steel pegs outside?
Yes — quality stainless steel pegs are designed for outdoor use and can generally be left outside long term.
For most households, 304 stainless steel performs very well outdoors and offers strong corrosion resistance for everyday weather exposure.
However, if you live:
- near the ocean
- in very humid conditions
- or leave pegs permanently exposed outdoors
316 marine grade stainless steel is usually the better option because it offers even higher corrosion resistance in harsher environments.
Choosing the right stainless steel grade for your climate can help your pegs last significantly longer.

Do stainless steel pegs leave rust marks on clothes?
High quality stainless steel pegs should not leave marks on clothes under normal conditions.
However, lower quality metal pegs or corroded stainless steel pegs may sometimes leave rust stains on washing over time.
This is more common in:
- coastal environments
- humid climates
- lower quality “stainless steel” products
- pegs left permanently outdoors
Choosing the correct stainless steel grade helps reduce this risk significantly.
How to stop stainless steel pegs from rusting
A few simple things can help extend the life of stainless steel pegs:
- choose the right grade for your environment
- use marine grade 316 near the ocean
- occasionally rinse pegs exposed to salty air
- store pegs undercover if possible
- avoid buying very cheap unknown-grade pegs
If you live near the coast, giving your pegs an occasional rinse or wash can help remove salty residue and extend their lifespan.
A simple soak in warm soapy water every few months is usually enough.
Which Biome stainless steel peg should I choose?
At Biome, we offer several stainless steel peg options depending on your environment and laundry needs:
- Standard peg — ideal for most everyday laundry
- Windy-condition peg — stronger grip for exposed areas
- Easy squeeze peg — easier handling and dexterity support
- Largest peg — suitable for doonas and heavier items
- 316 marine grade pegs — best for coastal homes and salty air
If you are unsure which peg is best for your home, read our stainless steel peg buying guide.
Customer review: “Have had these outside for years near the coast and they still look fantastic.”
FAQs
Do all stainless steel pegs rust?
No. Higher quality stainless steel pegs are highly corrosion resistant, especially marine grade 316 stainless steel.
What stainless steel pegs are best for coastal homes?
316 marine grade stainless steel pegs are the best choice for coastal and salty environments.
Why is marine grade stainless steel better?
Marine grade 316 stainless steel contains additional corrosion-resistant properties designed for salty and humid conditions.
Can stainless steel pegs be left outside?
Yes. For most homes, 304 stainless steel performs well outdoors, while 316 marine grade stainless steel is the better choice for coastal, humid or permanently exposed conditions.
Why do cheap stainless steel pegs rust?
Cheap pegs may use lower quality stainless steel with reduced corrosion resistance.
Do stainless steel pegs get hot in the sun?
Stainless steel wire pegs generally do not get too hot to handle because the thin wire does not hold much heat.
