The Mr. Hard water pro glass and window cleaner kit will clean and remove hard water spots from windows, shower doors and other glass surfaces. Designed for professionals and home owners, this kit is designed to take the guesswork out of hard water removal. Mr. Hard water powder contains absolutely no acids or chemicals and is perfect for removing tough hard water stains. Simply mix the powder with water to a paste, apply to the glass and polishing pad and you're ready to begin polishing. Both the powder and the liquid can be used with the nylon and the steel wool pads. I personally prefer the liquid with a steel wool pad! The system includes two types of polishing pads - nylon and steel wool. Start with the nylon. It's softer and less abrasive. If time is of the essence and the stains are not being polished away quickly enough, switch to the steel wool pads. Once cleaned and restored, envicoat glass sealant is a protective coating that will keep it cleaner longer and protect against further degradation. Apply with a sealer applicator or foam sponge. The sprayer is best used for auto/marine windshields. Use the sealer applicator or foam sponge to speed up your jobs and increase coverage rates. No dry buffing required. Cures in 3-5 minutes. After curing, rinse the glass with a wet cloth or a window cleaning strip washer. Then squeegee or dry. Envicoat is the most durable, safest and easiest to apply sealant on the market today!
