Before beginning a steam clean, sweep the area to remove any loose debris. Then, fill a steam cleaner with water and allow it to heat up. Once the steamer reaches operating temperature, begin cleaning the grout. Start by using a nylon-bristle brush for general maintenance and for most grime, mildew, and stains. If the surface is particularly dirty, you may need to move on to a brass-bristle brush for more intense scrubbing.
When you’re done, pause to rinse and/or mop or sponge each section that has been cleaned. It’s important to do this because it prevents dirty water from settling back into the grout and drying, which can lead to mildew and mold growth. A wet-dry vacuum on wet mode is also an effective way to quickly remove dirty water. You can then refill and reheat the steam cleaner as needed to continue with the cleaning process.
Unlike standard mops, which often require the user to scrub on hands and knees while applying detergent and scrubbing, a steam cleaner with an adjustable nozzle allows you to work from a standing position. It’s also much faster than manual scrubbing, which can save you a significant amount of time and effort.
If you don’t have a steam cleaner, you can still use a specialized grout brush and white vinegar to remove stubborn dirt. However, a steamer is the fastest and most effective way to do so.
It is also worth noting that sanded grout should not be steam cleaned frequently, as the high heat and moisture can damage it. It is also a good idea to test any new cleaners on an inconspicuous part of the grout before use. Finally, you should always be mindful of the type of grout, as some types (especially unsealed) can be susceptible to fading and bleeding from chemicals. Always follow the manufacturer’s instructions for your tile and grout to ensure proper care. It’s best to hire a professional to steam clean your tile and grout, as they are trained to identify different types of tile and grout and can offer tips for the best results. In some cases, they may even recommend additional steps to keep your tile and grout looking its best, such as sealing the grout after steam cleaning. This can help protect your investment and extend the life of your grout.
