Certain cleaning materials should be avoided when cleaning black granite as they can cause damage or dull the surface. These include: 1. Acidic cleaners: Avoid using any acidic cleaners like vinegar, lemon juice, or citrus-based cleaners. Acidic substances can etch the surface and damage the polish of black granite. 2. Abrasive cleaners: Stay away from abrasive cleaners or scrubbing brushes that can scratch or dull the surface of the stone. This includes scouring powders, baking soda, or any abrasive cleaning pads. 3. Harsh chemicals: Avoid using harsh chemicals, bleach, or ammonia-based cleaners. These can strip away the sealant on the granite and cause discoloration. 4. Windex or glass cleaners: Window cleaners like Windex or any other glass cleaners should be avoided as they can leave streaks and affect the sheen of the granite. Instead, use a pH-neutral, non-acidic cleaner specifically designed for natural stone surfaces. Additionally, using a soft microfiber cloth or mop to clean the surface is recommended to prevent any scratches.

Irans Hamadan Black Granite is known for its durability and resistance to weathering, making it suitable for exterior applications. However, using any natural stone in very rainy climates can pose some challenges. Here are some points to consider when using Hamadan Black Granite in such conditions: 1. Porosity: Even though Hamadan Black Granite is known for having a low porosity, it may still absorb some moisture. In very rainy climates, the excessive moisture might penetrate the stone, potentially causing staining or damage over time. 2. Sealing: To enhance the granites resistance to moisture, it is recommended to seal the stone properly. A high-quality penetrating sealer can help reduce its porosity and protect it from water damage. 3. Maintenance: Regular maintenance, including routine cleaning and resealing, is essential to keep the granite in good condition. This is particularly important in rainy climates, as the stone may be exposed to more moisture and be prone to the growth of moss, algae, or mildew. 4. Slope and drainage: Proper installation with the correct sloping and drainage system is crucial to ensure the water runs off the surface and doesnt accumulate around the granite. Standing water can potentially cause problems over time. 5. Frost resistance: If the climate is not only rainy but also experiences freezing temperatures, the granites frost resistance should be considered. Hamadan Black Granite is generally known to have good resistance to freeze-thaw cycles but understanding the local climate and the stones specific characteristics is important. In summary, Irans Hamadan Black Granite can be used in exterior applications in very rainy climates. However, extra care should be taken to properly seal, maintain, and ensure adequate drainage to mitigate the potential risks associated with excessive moisture.
