I’ve been using Koh since it was a relatively new company! I love it!! I have allergic reactions to many things and many products but not this!! It doesn’t smell, it works beautifully (I highly recommend the mop too by the way!), I spread brilliantly and goes a long way if you learn to trust the diffuser spray and don’t try to use it like a regular cleaner. It’s great on benches, stuff that needs gentle cleaning, floors but also ovens and tough things to clean! Also realise that KOH stands for the main chemical ingredient which is a nice stable but effective formula. I won’t go into the chemistry but it’s good and quite safe. Highly recommend!!
