HMK Stone Care of San Francisco, CA, has recently introduced HMK P1 3-in-1 spray, a ready-to-use product which has been specially developed for daily use on kitchen countertops, bathroom vanities, table and bar tops, windowsills and other surfaces made of natural or man-made stone. P1 cleans, maintains and protects in one simple application, enhancing the beauty of existing surface while providing protection. Special ingredients in P1 enhance the performance of HMK impregnators (such as S34 Silicone Impregnator and S32 water-based Impregnator), according to the company. P1 easily removes light dirt and grease while releasing a pleasant scent. Color and structure of the surface remain practically unchanged. P1 is a solvent-free product. After drying, it is non-hazardous to your health, as the product has been LGA tested, reports HMK.
