Why Granite Loses Its Shine (and Why Cleaners Make It Worse)

Granite is tough, but it is not immune. Here are the five real causes of dull granite in Chicago-area kitchens and which ones can be fixed at home.

What you are seeing is one of five things, and most of them are fixable. 1. Residue build-up The most common cause, and the easiest to fix. Spray cleaners, dish soap and especially "granite polish" products leave a film. Layer after layer builds a dull, slightly sticky haze that traps grime. Under a flashlight it looks like streaks that never fully wipe away. Fix at home: wash with warm water and a small amount of a pH-neutral stone cleaner, then rinse with clean water and dry with a microfiber towel. Stop using topical polishes. 2. Abrasive cleaners and scrub pads Powdered cleansers, magic-eraser sponges and the green side of a kitchen sponge are all abrasive. Individually each pass is harmless; over a few years they put thousands of micro-scratches into the polished surface. Light stops reflecting cleanly and the stone looks grey. Fix: this requires mechanical repolishing. It cannot be reversed with a product. 3. Sealer failure When impregnating sealer wears out, water and oils soak into the stone. Darkened areas around the sink and cooktop are the tell. The stone is not dull so much as stained and patchy . Test: put a few drops of water on the counter and wait 10 minutes. If it darkens the stone, the sealer is gone. Fix: deep clean, optionally poultice any oil stains, then reseal. If the surface is also scratched, hone and polish f
