How to Clean Your Sub-Zero Stainless Steel Exterior: Step-by-Step Guide
Keeping your Sub-Zero refrigerator looking as sleek as the day you bought it doesn’t have to be a challenge. With the right tools and techniques, you can maintain that signature shine without streaks, smudges, or damage. Follow this step-by-step guide to clean your stainless steel exterior the right way.
1.) Wipe Down the Surface with a Damp Microfiber Cloth
Before applying any cleaner, remove dust, fingerprints, and light smudges with a microfiber cloth.
- Lightly dampen the cloth with warm water and mild detergent.
- Gently wipe the stainless steel exterior, ensuring even coverage.
- Avoid abrasive pads, paper towels, or harsh cleaners—these can cause fine scratches or dull the finish.
2.) Apply Stainless Steel Cleaner or Mild Soap Solution
For a deeper clean, use a stainless steel cleaner or a mild soap solution.
- If using a stainless steel cleaner, spray a small amount onto a clean microfiber cloth (never directly on the fridge to prevent streaks).
- If using mild soap and water, dip the cloth, wring it out well, and wipe down the surface.
- Use only a minimal amount of cleaner—excess liquid can leave streaks or residue.
3.) Wipe with the Grain
Stainless steel has a grain—fine lines that run either horizontally or vertically.
- Always wipe in the direction of the grain to maintain the natural finish and avoid streaking.
- Never wipe in circles or against the grain—this can create visible smudges and make dirt harder to remove.
4.) Buff and Protect with Signature Polish
For the best results, finish with Sub-Zero’s recommended Signature Polish.
- Use a dry microfiber cloth to buff away excess cleaner and bring out a fingerprint-resistant shine.
- Apply Sub-Zero Signature Polish (if your model allows) for extra protection against smudges and streaks.
- Check your owner’s manual first—some Sub-Zero models have a coated stainless steel finish that shouldn’t be polished.

Troubleshooting: Common Stainless Steel Cleaning Issues
- Still looks dull? A small amount of white vinegar on a microfiber cloth can restore shine.
- Streaks won’t go away? Re-wipe with a clean, dry microfiber cloth, always following the grain.
- Grease or sticky residue? Use a tiny drop of Sub-Zero Stainless Steel Cleaner & Polish on a cloth to break down tough grime, then wipe clean.
Pro Tip: Use a Dry Microfiber Cloth Daily to Prevent Buildup!
To keep your Sub-Zero looking its best between deep cleanings, wipe down the stainless steel exterior once a day with a microfiber cloth. This simple habit removes dust, fingerprints, and light smudges before they have a chance to build up, keeping your fridge looking spotless with minimal effort.
