How to Care for Stainless Steel: What Damages It (and What Doesn't)

4 min read

Stainless steel protects itself with an invisible layer that renews itself when the surface is kept clean. Harsh pads and chemicals break that layer down and actually invite rust — which means most of the damage people blame on "bad stainless" is really damage from how it was cleaned.

The Method: Gentle Is What Lasts

The core rule is simple: soft tools, mild products, and always work with the grain — the fine brushed lines in the steel — never across it.

Start gentle. Warm water, a little dish soap, and a microfiber cloth handle everyday grease and grime. Wipe with the grain, rinse, and dry.
For surface rust, use Zep Oven Cleaner, then follow with Zep Stainless Steel Polish. Applying a stainless polish after any stronger cleaner is critical — whatever the brand — to reseal and protect the surface.
Rinse thoroughly. Don't let a stronger cleaner sit on the surface — rinse it away well so no residue is left behind.
Dry completely. Water left to air-dry, especially hard or salty water, leaves spots and can start the rust cycle again.
Protect. Once dry, an occasional wipe of stainless polish restores the shine and adds a light protective barrier.

Do This

Clean with the grain of the steel, every time
Use microfiber, soft cloths, nylon brushes, or non-scratch pads
For surface rust, use Zep Oven Cleaner, then finish with Zep Stainless Steel Polish — always polish after a stronger cleaner
Rinse fully and dry completely after every clean
Treat rust and stains the moment you notice them

Avoid This

Steel wool and wire brushes — they scratch the surface and leave behind tiny iron particles that rust and stain the stainless. Often, the "rust" people see isn't from the appliance at all — it's this. It's the most common, and most avoidable, cause of surface rust, and damage from improper cleaning isn't covered under warranty.
Bleach, ammonia, and chlorine cleaners
Scrubbing across the grain, or in circles
Letting any cleaner sit on the surface
Leaving the appliance wet, or letting salt and grease build up

If You Spot Rust

Light orange or brown staining is almost always superficial — sitting on the surface, not eating into the steel. Start with the surface-rust method above (Zep Oven Cleaner, then Zep Stainless Steel Polish). If that doesn't fully lift it, work the spot gently with Bar Keeper's Friend and a non-scratch pad along the grain, then rinse, dry, and polish. If rust keeps returning in one spot, look for a nearby steel tool or fastener shedding onto it.

Why Your Jupiter Appliance's Design Matters

Jupiter grills, side burners, and refrigerators are built from premium stainless steel chosen to resist corrosion — but nothing that lives outdoors is truly rust-proof. Left alone, salt air and grease will eventually dull the finish and leave light surface rust. Ten minutes of care, at the right moments, is all it takes to prevent it.

If you're in a coastal environment specifically, rinse exterior stainless with fresh water and dry it weekly — and after any storm or heavy salt spray. Salt left to sit is the single biggest cause of surface rust.
