Before You Start
Inspect the area for loose mortar or damaged veneer and repair before cleaning. Work in shaded conditions to avoid rapid drying that can leave streaks.

Important: never use bleach on dark stones or acid-based cleaners that can etch natural stone.

Buying Guide
When choosing products for stone veneer care, consider size and spacing of the veneer, surface porosity, and the level of maintenance desired. Look for a comprehensive kit that includes ergonomic tools, a safe cleaning solution, and a dedicated nozzle. Noise levels and energy use are typically not major factors for cleaning tools, but consider a comfortable, low-effort setup for regular upkeep. Evaluate whether you need extendable brushes for high sections or a compact kit for interior applications. Compare a standalone stone veneer cleaner concentrate versus a ready-to-use cleaning kit to determine what best fits your routine and budget. Placement matters: exterior walls facing weather and interior fireplaces require more frequent care and gentler methods to preserve aesthetics and longevity.
