What are the best methods for preventing efflorescence on marble bar stools?

Efflorescence, the unsightly white residue that forms on marble surfaces, can be a common issue for marble bar stools. To prevent this, start by sealing the marble with a high-quality penetrating sealer, which creates a protective barrier against moisture absorption. Regularly clean the stools with a pH-neutral cleaner to avoid chemical reactions that can lead to efflorescence. Ensure proper ventilation in the area to reduce humidity, as excess moisture is a primary cause of efflorescence. For existing efflorescence, gently scrub the surface with a soft brush and a mixture of water and mild detergent, then rinse thoroughly. Finally, avoid placing marble bar stools in damp or high-humidity environments to minimize the risk of efflorescence recurrence. By following these steps, you can maintain the beauty and longevity of your marble bar stools.
