This could also be such a tip in which is immediately shouted "Old hat, long known". I bring him anyway and dedicate it to all the unsuspecting and "left behind":
Recently, I discovered "wet wipes for leather care" in the drugstore. That would be something for my black leather sofas, I thought. Tried and - totally excited.

The tin with the special leather fat will probably dry up slowly now.
