Amazing Koh, I am very excited about Koh as I am allergic to plenty of cleaning products and always try to use natural products. After testing Koh, I am a converter, your Koh product is extremely effective and I have nothing else to compare, since first trialling it 3 years ago, I have just ordered my 3rd lot also sending a pack to my daughter in Geelong. Great product people. Not a single allergy reaction at all - I love it.
