Maintenance

Blue Perla Limestone should be cleaned regularly using a pH-neutral stone cleaner and a soft cloth or mop. Avoid acidic cleaning products, vinegar, lemon juice and descaling agents, as limestone is calcium-carbonate-based and can be easily etched by acids. A suitable penetrating stone sealer is recommended to reduce liquid absorption and staining, particularly in bathrooms, kitchens and high-traffic areas. Spills should be cleaned promptly, and abrasive pads or harsh chemicals should be avoided. Exterior installations should use appropriate drainage, frost-resistant installation materials and suitable sealing procedures according to local climate conditions.
