ÁTHOS bathroom cleaner did a really good job on the grimy grout and surface of my stone shower. It did an even better job on the grout on the floor of my white kitchen. I sprayed it on, used a brush on the grout to remove the grease and grime, then wiped it with a damp cloth, cleaning the surface of the stone as I went. Today I tried it on the glass bowl sinks, toilet, and counter top in my bathroom. I appreciate that it’s non-toxic, works so well, and I love the peppermint scent.
