I started using Koh when they used their old name and you could only purchase on-line. Being a senior, the domestic help required that I not use caustic cleaning products. A lung condition also meant that such products were bad for me. I was instantly amazed by the effectiveness of their cleaner and became a dedicated purchaser.
Nowadays I use their other products - including mops, dishcloths, scrubbing pads, Laundry products, and toilet tablets (which I place in the water tank of the toilet to stop the build-up of bacteria, etc.)
Now you can purchase Koh products via the supermarket in much easier-to-handle bags which is a real asset to me (due to arthritis) which precludes me from lifting heavy items.
Thank you Koh. I have always recommended your products to my friends and associates who have also become Happy Koh users.
