I have been using them for a while now and I really like them. My washing machine stays fresh. Before using these, I used washing machine cleaner every week, but they made my washing machine cleaner and my clothes and towels look beautiful and fresh. No moldy smell, no bacteria. I use them every time I wash clothes. fantastic.
I know this product from Europe, and I know its effectiveness is excellent. You don't need to clean your washing machine separately, and there will still be residue. You can use this product to clean them, they are clean and hygienic, and your washing machine is also very clean. My washing machine is even starting to sound like new. It's a bit expensive, I hope to buy it at a lower price, but I really recommend it!!!
