Cleaners - Slate

Our slate cleaning products are specially formulated to clean this layered, natural stone effectively while preserving its structure. Slate’s composition can make it sensitive to certain harsh chemicals, so using products like sodium hypochlorite—often a strong cleaning agent for other surfaces—can lead to undesirable effects, including discoloration or delamination of the stone. For this reason, we do not recommend sodium hypochlorite on slate surfaces.

Instead, PureSeal’s slate cleaners utilise targeted, gentle formulas that lift dirt, algae, and organic buildup without harming the stone’s texture or appearance. Our products are designed to work deeply on slate surfaces, ensuring a thorough clean while maintaining the stone’s original finish. Always adhere to product instructions and use recommended PPE for safe handling. With PureSeal’s slate cleaning solutions, professionals can effectively maintain and restore slate, preserving both its beauty and durability without risking chemical damage.
