A stronger product is not always the right product. pH, dwell time and application equipment directly affect a surface’s appearance and life.\n\nAcidic products may permanently mark natural stone, while excess moisture can move timber. On glass, the correct cloth and dosage often matter more than the brand.\n\nA professional approach starts with a compatibility test in a discreet area. Safety data sheets are followed, products are never mixed and only the required amount is used.
