The Sörbo traditional classic Yellow Jacket™ washer sleeve with brass snap closure. Micro washing sleeve washers have been very popular since the 90’s and Sörbo is the only company that has never changed the high quality, high performance material. It holds much more water which makes it possible to wash many more windows without having to re-wet every window. It also lays the water on the window much more evenly with less effort. Sörbo also knows how important it is to have a long-lasting washer and is aware that ends wear out too fast, so we inserted a protective material on each end in sizes of 18″(45cm) to 36″(90cm) that will flip back and forth and minimize wear against frames. Sörbo introduced the first 6″ and 36″ Yellow Jacket washer with T-bar to the window cleaning world in 1994. We recommend that you wash all new washer sleeves in a washing machine before use to remove most of the loose fibers. This limits the possibility of streaks. However, do not use dryer fabric softener as it makes the washer sleeve less absorbent.
