Quartz brick is a commonly used road building material in municipal facilities nowadays. It is made by screening, forming, drying, and high-temperature sintering ceramic raw materials.
1. When cleaning quartz bricks, if only water cleaning cannot remove gelatinous sludge and water stains, decolorize with hydrogen peroxide water or clean with household detergent, and then thoroughly clean with water.
2. Apply cement slurry to fully wet the joints between tiles with water, then rinse thoroughly with 2-4% hydrochloric acid solution and water. After sweeping the mud and sand with a broom, gently scrub them with a brush dipped in 0.2-0.5% sodium phosphate solution
3. The gum on the quartz brick can be removed with a knife first. If some areas are difficult to scrape, they can be scraped off with frozen salt and ice. Spray alcohol or dilute hydrochloric acid solution on top, then rinse with water.

Several points to note when burying quartz bricks:
1. Clean the surface of quartz bricks with exterior wall cleaner by rolling and spraying the coating, then use a brush to wipe until clean, and rinse with clean water.
2. For heavy dirt or 1-day wall heavy dirt that has not been cleaned for many years, it is necessary to roll the cleaning agent on the cleaning surface, wait for a few minutes, let the cleaning agent wet the wall surface, dissolve and use a brush or cleaning cloth to wipe it. If it is not completely removed at once, it can be cleaned repeatedly until it is clean, and then rinsed with water.
3. The dilution ratio of the cleaning agent is 1:1-3. If cleaning heavy dirt quartz bricks, it is necessary to prepare it in a 1:1 ratio or directly use the original solution.
4. For sensitive wall tiles and rubble, please try them out in inconspicuous areas before use for the first time.
