Powdery Mildew on my Cucumber leaves

So I have noticed on one of my cucumber plants the leaves have these white spots. I looked it up and found out it was powdery mildew. Most of what I am hearing is that Neem Oil is a good way to get rid of this, but what if some of the leaves are dried up? Should I just cut them off?

What are some things that have worked for you?

If the leaves have dried cut them off. You can also use a solution of 1 part milk to 9 parts water, to every gallon of solution add 1 T of baking soda. Spray on in the morning and let the sun do the rest. This is really to control it and keep it from spreading. Like the more expensive Neem treatment it has to be reapplied after every heavy rain or about every 3 weeks whichever comes first.
