What cleaning materials should not be used on black granite?
When cleaning black granite surfaces, it is important to avoid using cleaning materials that can potentially damage or dull its appearance. Here are some cleaning materials to avoid when cleaning black granite: 1. Abrasive materials: Avoid using scouring pads, steel wool, or abrasive cleaners that can scratch or dull the surface of the black granite. 2. Acidic cleaners: Stay away from acidic cleaners like vinegar or lemon juice, as they can etch the surface and cause damage. 3. Bleach or ammonia-based cleaners: These harsh chemicals can strip away the sealant on the granite and cause discoloration or damage. 4. Oil-based cleaners: Avoid using oil-based cleaners or polishes as they can leave a greasy residue or even blotches on the granite surface. 5. Alcohol or vinegar-based products: Although alcohol-based products are commonly used for cleaning, they can be too harsh for black granite. Instead of using these materials, it is recommended to clean black granite with mild or pH-neutral cleaners specifically designed for natural stone surfaces. Additionally, using a soft, non-abrasive cloth or sponge for cleaning and drying with a clean, lint-free cloth will help to maintain the shine and appearance of black granite.
