"Dossier Sink Plug Strainer"
After reading some of these reviews, I thought I should add my own to say, I too have found it impossible to remove the black deposits on the reverse of the cover, even after soaking in a strong bleach solution. Although the cover works very well, I’ve had to dispose of it and am reluctant to buy another. I’ve ordered a different make via Amazon today, hopefully I won’t have the same problem. Still love Lakeland’s products though.
