Tile and grout can get dirty and grimy over time - hire a home service pro to make them look as good as new again. To keep your grout looking good post clean up, try spraying your shower with 1:1 vinegar and water mix a few times a week.
Excellent and very professional. Would highly recommend. Our travertine marble foyer/kitchen area looks brand new. Paid great attention to detail and it looks like new. Will definitely use their service again. Thank you.
