How can I treat this white stuff on my boxwood leaves?


I have two boxwoods in the front of my house, it gets plenty of sun, not too much watering. About a year in we got this awful white looking stuff on the leaves. I have tried soapy water with a little vinegar, and neem oil. Do I need to cut this out and let it be ugly for a season?
