How to Remove Stains From Quartz, Granite, and Marble Countertops
To maintain the quality and appearance of stone countertops, specific cleaning methods are required. Using the wrong cleaners can damage natural stone materials such as granite and marble. [1] This guide explains how different counter materials stain and provides reliable, straightforward methods for successful spill clean-up. Differentiating Staining Mechanisms in Stone Surfaces The ease with which a counter stains depends primarily on two material factors: porosity (how much liquid the surface absorbs) and how much it reacts to acid. [1] Countertop Type Porosity Acid Sensitivity Staining Mechanism Marble Highly Porous Highly Acid-Sensitive Oils and food can penetrate the surface, and acidic cleaners will cause dull spots (etching). [2] Granite Moderately Porous Moderate Requires regular sealant application; depleted sealant allows water and oil penetration. Quartz (Engineered) Non-Porous Low It resists most stains well, but harsh cleaners or high heat can damage the material. Micalline Kornerstone Non-Porous None Does not stain. [4] Warning: Unsuitable Cleaning Products Homeowners must be cautious: many everyday cleaning products are unsuitable for natural stone. [2] Avoid these substances: For routine cleaning, use only mild dish soap and warm water, or a cleaner made specifically for stone. Simple Stain Removal Steps It is recommended to clean stains immediately, but if a stain has dried, follow these recommended steps: [3] 1. Water Spots (Hard Water/Soap Scum) Countertop Cleaning Method Granite & Quartz Gently scrub the area using ultra-fine 0000 steel wool and mild dish soap. Marble Make a paste using baking soda and water, put it on the spot for five minutes, and then wipe it clean. It is crucial to avoid all acids. 2. Oil Stains (Grease, Cooking Oil, Lotion) Oil stains are challenging because they penetrate the material deeply. A special mixture called a poultice is required. [3] 3. Food Stains (Coffee, Tea, Wine) Countertop Cleaning Method Granite & Marble Put a few drops of hydrogen peroxide (or diluted ammonia for dark stains) right on the spot. Quartz Use a mild, gentle household cleaner or rubbing alcohol. The Micalline Kornerstone Advantage: Exceptional Durability For complete protection against staining worries, Micalline Kornerstone (sintered stone) is an ideal choice. This modern surface is manufactured under intense heat and pressure, rendering it 100% non-porous—which means liquids cannot be absorbed. [4] This advanced material provides significant benefits: Routine cleaning of Kornerstone requires only soap and water. When to Consult a Professional If a deep stain persists after two applications of the homemade poultice, professional assistance is recommended. [3] Really bad stains or etching might require professional services, including specialized grinding, polishing, or commercial poultice application. Micalline provides guidance on subsequent actions, including suggesting certified stone repair experts or discussing replacement options if the damage is too serious. Our commitment is to help you maintain the long-term beauty of your stone surfaces. Sources
