BUY. We think the simplicity of the tablet formulation of DOKIKO Windshield Washer Fluid Concentrate is fantastic. The tablets are easy to use and dissolve really quickly in water. We also love that we don’t have to drive to buy another giant plastic jug again! Note: we are not advocating that the ingredients are better than traditional washers; we simply love the drastic plastic reduction because of the concentrated formula. As a huge bonus, the tablets are SO much cheaper t AND easier to store than traditional windshield washer fluid.
