Once a month?

I don't do anything at all.
Stop using it in the fall, start it up in the spring.
I have a 2 cycle string trimmer that I sometimes don't start for a
year or 2. Starts fine when I want to use it.
Who makes up these time wasting rules?

I'm 30 years into my mowing business. All my
equipment is left alone unstarted for 3-4
months each year. It used to be that I'd not
even drain the fuel at the end of the season, tho
that is no longer the case. No issues whatsoever.

So why did you switch to draining the fuel?
