The best way to clean grout.
Attach a small brush to the steam lance and begin by steaming straight onto the grout line. Use the brush to lightly scrub as you go. Dirt will be lifted from the grout effortlessly. Finish the job by attaching a microfiber cloth to the rectangular tool, then pass over the entire surface to wipe away excess dirt.
Steam gives you perfect results. To clean dirty grout lines, select the rigid nylon detail brush on delicate grout or the brass detail brush for more resistant grout.
