Self-cleaning surfaces

Self-cleaning surfaces are specially designed materials that automatically remove dirt, water, and other debris, keeping themselves clean with minimal effort. They often utilize a technology called "superhydrophobic" or "photocatalytic" coatings, which repel water and cause dirt to slide off or break down when exposed to sunlight. This reduces the need for frequent cleaning and helps maintain hygiene and appearance. Common applications include windows, solar panels, and building exteriors, where maintaining cleanliness enhances durability and efficiency while saving time and resources.
