I don't buy anything else... koh universal cleaner, koh laundry liquid (gets rid of the funky washing machine smell and can get out stains as a pre-wash stain remover - genius!), koh loo blades are fabulous, koh dishwasher tablets! Koh loo tablets got a very horrid mess dissolved after days of our toilet being blocked where the paper had formed a layer on top of the water but I just couldn't get it cleared... 3 koh loo tablets after breaking that seal, let it soak for 1/2 hr and add a bucket of hot water... all gone and the toilet was clean to boot! We just moved house and the packers had packed the dishwasher tablets before I could pull some out, so we couldn't find our koh dishwasher tablets for about a week, so had to borrow some 'leading brand' tablets from my sister-in-law... I'd not had any residue for years using Koh dishwashing tablets, but the 'leading brand' certainly did leave it's residue!!! I love koh products and even give free samples to friends as they are just such good products!
