To protect a Black Gold Marble kitchen countertop, follow these steps:

1. Sealing: Marble is a porous material and requires sealing to prevent staining. Select a high-quality marble sealer suitable for Black Gold Marble. Apply the sealer as per the manufacturers instructions, ensuring that the countertop is completely covered. Allow it to absorb into the stone and wipe off any excess sealer.

2. Daily cleaning: Clean the countertop daily using a non-abrasive cleaner specifically designed for marble. Avoid acidic or harsh cleaners that can etch or damage the surface. Use a soft cloth or sponge to wipe away spills and stains promptly.

3. Avoid acidic substances: Acidic substances like citrus juices, vinegar, and certain cleaning products can cause etching on marble surfaces. Be cautious and wipe up any spills immediately to prevent damage. Use coasters or placemats under acidic items to provide an extra layer of protection.

4. Avoid sharp objects and abrasive materials: Marble is susceptible to scratching, so avoid using sharp objects directly on the countertop. Always use cutting boards or other protective measures when working with knives or any other sharp utensils. Additionally, avoid using abrasive materials or scrub brushes that can scratch the surface.

5. Heat protection: While marble can handle moderate heat, it is still advisable to use trivets or heat-resistant pads under hot pots, pans, or other heated objects to prevent any possible damage or discoloration.

6. Regular maintenance: Periodically reapply the marble sealer according to the products instructions or when water no longer beads on the surface. Regularly clean the countertop to prevent the build-up of dirt and grime.

By following these steps, you can effectively protect and maintain your Black Gold Marble kitchen countertop, extending its longevity and keeping it looking beautiful.
