“I was certainly skeptical about buying this product, but I had a few friends recommend it for being a safer cleaning product. On the very first clean it worked its magic. We had a habit of having foggy shower screens and a basin that needed some work - Koh took care of both of them with no effort at all.
While I was riding a cleaning high, I even took on the heavily stained washing machine lid - Koh with the scrubber corners got it almost to being brand new. From aged and stained to 99.9% with just a single application, a little time and a little elbow grease.”
“This product was recommended to me by a friend as I was struggling to find an induction hob cleaner that didn't actually leave smears on the glass. This does the trick, and on my quartz surfaces too.
Not sure about the black "diamond" sponges, I dare not attempt to use them on my glass as they actually feel like glass edges themselves.
Cloths are great, and have a small corner to scrub with should you need it.
Not sure what the liquid is, it has no smell so its not clear if this is anti-bacterial or not, but seems to do the job. I only use it in my kitchen so far, but may invest more in the future.”
