Most cleanings can last up to 6 months. Use our grout cleaner for routine maintenance to keep your tile and grout looking new all the time! We have found that a high quality grout cleaner can eliminate grout sealers. We know that grout sealers do not offer any type of water resistance or water proofing either, and have not found any literature on these products that suggests this type of protection.
Keep in mind that high quality grout sealers are needed for natural stone such as: granite, travertine, slate, marble and limestone. Sealers do help protect from damaging liquids such as oils, ketchup, red wine from permanently staining your natural stone. Keep in mind that spills need to be wiped up immediately for best results. Even the highest quality sealers offer limited protection against stains.
