Our cleaning technicians work to the best of their ability to have your home cleaned to the highest standard, but there are limits to what we are able to do with set-in stains or certain textured or porous surfaces, such as fabrics, wood, shower doors, bathtubs, grout, countertops, etc. We will clean these surfaces as thoroughly as we can, but they may not appear as visually clean as other types of surfaces. If there is hard water with high mineral content in your home, it may have caused permanent staining or build up in your bathrooms and kitchens. We do everything with the highest care and standard, we cannot guarantee that the hard water stains can be removed. Additionally, there are other things we do not clean.
