Types of corrosion we see
Tea staining is the brown or orange discoloration on stainless hoods and panels, common within a few miles of the coast. It's surface level and usually comes off. Pitting is small, deeper spots where corrosion has eaten into the metal. It can be smoothed and treated but not fully reversed. Rust-through means a part has corroded all the way through, which happens mostly to burners, heat plates, grates and the bottom of fireboxes.
Where corrosion is matters more than how it looks. A stained hood is cosmetic. A rusted-out firebox floor or burner is a functional and safety issue.
What causes it, most common first
Salt air
Salt in the marine layer settles on stainless and breaks down its protective layer. Beach cities see this the most.
Learn moreGrease and food acids
Grease left in the firebox holds moisture and acids against the metal and eats it from the inside.
Sprinklers and hard water
Sprinklers hitting the grill leave mineral spots and keep it wet. Hard water in much of LA adds to the staining.
Chlorine and pool chemicals
Grills near pools, or stored near pool chemicals, corrode noticeably faster.
Wrong cleaners
Bleach, chlorine cleaners and steel wool damage stainless and can start rust spots.
Lower grade stainless
Some grills use stainless alloys that are more prone to rust, especially on internal parts.
What you can safely do
- Wipe the stainless with warm water and mild soap, then dry it. Always wipe with the grain.
- Use a cleaner made for stainless steel. Avoid bleach, chlorine-based cleaners and steel wool.
- Redirect sprinklers that hit the grill.
- Rinse salt off coastal grills occasionally with fresh water and dry them.
- Check under the grates for rusted burners or heat plates. Those affect function and safety.
- Look at the bottom of the firebox with a flashlight for holes or flaking.
How we treat corrosion
- 1
Assess honestly
We sort what's cosmetic from what's structural or safety related, and tell you which is which.
- 2
Deep clean
Grease and grime come off first, because corrosion can't be treated under a layer of grease.
- 3
Treat stainless
Staining and light pitting get treated and polished with the grain using products made for stainless.
- 4
Replace rusted parts
Burners, heat plates, grates and hardware that have rusted through get replaced with matched parts.
- 5
Protect
A protective treatment helps the stainless resist staining, and we'll give you a simple care routine.
When it's too far gone
Most corrosion problems are fixable. The exception is a firebox or housing that's rusted through structurally. Fireboxes are usually not a replaceable part, and if the shell itself is failing, we'll tell you. At that point, replacing the grill in the same island cutout is often the better choice. Our repair or replace guide lays out how we think about it, and picking a grill for a coastal home covers which builds hold up best near the water.
For grills that need more than a repair or two, our restoration service handles the whole package.
Rust and corrosion questions
Why is my stainless grill rusting?
Stainless resists rust but isn't immune. Salt, chlorine, grease, hard water and some cleaners break down its protective layer. Lower grade stainless is more prone to it.
Can the brown stains be removed?
Usually, yes. Tea staining is surface level and comes off with proper cleaning and polishing. Pitting can be improved but not fully erased.
Will a grill cover prevent rust?
It helps with sprinklers and debris. Near the coast, a cover can trap moist, salty air against the grill, so it needs to breathe and the grill should be dry before covering.
Is a rusty grill safe to use?
Cosmetic rust on the exterior is fine. Rusted burners, heat plates, fireboxes or gas parts should be inspected before you cook.
How much does rust repair cost?
It depends on the extent of the damage, the parts needed and the brand. Send photos of the hood, the firebox and the burners for a quote.
