I highly recommend investing in a power washer. I think mine was $175 from Home Depot. I have 5 screens that I've been reusing for the past 2 years, and all I do is blast out all the emulison and screen filler with water after I'm done. Sometimes Ulano Haze Remover is necessary, but I just make sure to wear gloves and a respirator. Take care of yourself-- your health is most important!
