DIY grout cleaning
Updated: Nov 18, 2019
Here is a simple grout cleaning project, a small bathroom. The bathroom grout will be an easy project to get the hang of things. The basics for this job are the same for harder jobs: dwell time, agitation, and extraction.
One will need a detergent, grout brushes like in the photo, and a bucket with an absorbent rag. Laying down a towel or drop cloth at the doorway gives a nice place to wipe the feet off. The best place to buy cleaning products and tools is a janitorial supply store. Taking the time to Google janitorial supply stores in ones area is time well spent. Stay away from acid detergents. Acid is hard on the skin, eyes, metal, and carpet.
After sweeping the floor, put the detergent into the grout lines. Make sure to dilute the detergent if required in the directions. Over diluting the product is a good idea. Many products are difficult to extract because they are concentrated. It's better to over dilute. Try to only fill the grout lines in order to make the extraction easier.
Most detergents require a 10 dwell time. The grout lines must stay wet during the whole cleaning process. After 10 minutes, agitate the grout lines with a grout brush. The toothbrush one is great for getting into the corners. Once the scrubbing is done, use the rag and bucket to mop up the detergent and dirty water. Keep wringing the rag out and wiping the floor (especially the corners) until everything looks nice.
Now that wasn't too bad and maybe a larger, more ambitious job is next. Kitchen tile and grout can be a lot of work (that's why people hire me). One will need a good mop for larger areas. A shop vacuum works if one wants to flood an area with detergent. Remember the basics of floor cleaning: dwell time, agitation, and extraction.
