 The shift to easier to clean vinyl seats has already started, with WMATA making the change in about 40 of its buses. And riders like Daniel Pintard welcomed the change. Very often, especially with the fabric sort of lining they have, it can pick up dirt and a lot of muck on it very easily. So yeah, hopefully the vinyl will make it easier to clean. Zoe Arbor, who usually favors metro trains over buses, agrees the move from cloth seats to vinyl is a smart one.
