Cleaning Natural Stone Surfaces in Ontario Homes
Natural stone — marble, granite, quartzite, travertine, slate, and limestone — is increasingly common in Ontario homes, particularly in kitchen countertops, bathroom vanities, and floor tiles in premium construction. Stone surfaces require specific cleaning approaches that differ significantly from ceramic tile, laminate, or quartz composite, and using the wrong products can permanently damage them.
The pH Rule for Natural Stone
The most important rule for natural stone cleaning: use only pH-neutral products. Acidic cleaners (vinegar, citrus-based cleaners, many bathroom tile cleaners) will etch the surface of calcite-based stones — marble, travertine, and limestone are particularly vulnerable. Alkaline cleaners can strip stone sealants. pH-neutral stone-specific cleaners (Stone Tech Professional, Method Daily Granite Cleaner, or similar) are the correct tool.
Granite vs. Marble: Key Differences
- Granite: More resistant to etching than marble — its silicate mineral composition doesn't react with acid the way marble does. However, granite still benefits from pH-neutral cleaners and periodic sealing
- Marble: Beautiful but sensitive — even light acid contact (a lemon squeezed on a marble counter, vinegar splash) can cause etching (a dull ring) that requires professional polishing to address
- Quartzite: A silicate rock (unlike quartz, which is engineered composite) — more acid-resistant than marble but benefits from pH-neutral care
Hard Water Deposits on Stone
Hard water deposits on natural stone cannot be removed with vinegar (which etches stone). Use a stone-safe descaling product, or consult a stone care professional for significant mineral deposit removal.
