"disappointing" star star star star_border star_border I am not sure whether this is protecting my washing machine and will continue using it in the hope that it is! However, I have noticed no improvement in the results of my laundry, which is disappointing - tea towels still come out stiff as a board, towels and flannels are like sandpaper. I have tried everything - vinegar in the rinse, I also use anti-limescale tabs in the wash, and thought I would try this too. No noticeable improvement but hopefully it is at least protecting the machine itself. Miss Gardner - 12 March 2021 support_agent A note from the team Thank you for placing your review.
