I love it. I haven’t found it’s that great on the oven or on limescale (with or without the diamond sponge) but it’s as good as anything else you can buy. . Apart from those two things I thinks it’s exceptional on everything else, floors, counters, the hob, mirrors, glass, walls, woodwork etc. I’ve even used it on old carpet stains and it’s worked very well.
Before CoVid I quite liked that it wasn’t anti-bacterial as I think a sterile home isn’t good for the immune system but I’ve been more cautious over the last few months and I’ve found adding a splash of Zoflora to the spray bottle of Koh has the double benefit of making it antibacterial and making it smell lovely without compromising its efficacy.
