Dear friends, I didn't like to clean the magnet side of the T7 water trough from captured steel particles. So I sealed a strong magnet in a plastic foil (picture 1). In the trough it is held by the existing magnet of the trough (picture 2). Most of the steel particles now are collected by the strong magnet in the foil. For cleaning the magnet with the surrounding foil can be removed (picture 3) and cleaned easily outside the trough.
Good idea!
Excellent idea, I think I will copy you!
Interesting idea. I have always just taped a magnet to the outdide of the water trough with black electrical tape, which lasts "forever".
I drain almost all of the water with a turkey baster; wipe the trough with a paper towel; and give the trough a final quick rinse.
