I got onto Koh when I was visiting my mum and noticed the Koh Grout Brush. I run a cleaning business and was keen to try the brush out. It is what I was looking for for my business and as well as my own home cleaning. I also tried her Diamond Sponge and again was amazed with the results I got. I was sold and bought a kit and since then love how Koh products help me in my cleaning business and in my own home.
