3 Magic Eraser Stain Remover Cleaning Blocks 5 "Who would have thought..." Mrs Farrer 18 May 2020 We live in the southern Mediterranean and this is the best product ever for cleaning the stains that build up on the water line of our swimming pool. For years we have been buying expensive chemicals for the annual clean at the beginning of the season. Took us half the time, no chemicals, fraction of the price and did a better job! Totally thrilled. A cracking product Lakeland - well done!
