This method of cleaning involves the application of an acidic solution directly to a surface, such as a swimming pool, without the preliminary step of completely removing the water. The concentrated solution reacts with stains, mineral deposits, and algae, loosening them from the surface. For example, this procedure can effectively eliminate stubborn calcium buildup on pool tiles or plaster.
The primary advantage lies in the significant reduction of water consumption and associated costs. It also decreases the time and labor required for a traditional cleaning, making it a more efficient option. Historically, such practices were developed in response to water scarcity and a growing awareness of environmental conservation.
