“To be honest I was sceptical of the claims Koh were making about their products and what they would do. It may be old school but in my experience if it sounds too good to be true then it probably is. Still with a money back guarantee I had nothing to lose and I am so glad I did. I've tested the Koh cleaning system out on everything I could think of in the last month from my oven to my jewellery and I haven't been able to fault it yet. No fumes, no residue and everything's coming up spotless. I'll definitely be buying again and gifting a few bundles as well.”
