A quarter cup won't even flush out the trap. I don't think that is nearly enough.
I flush out my condensate drain with a garden hose until clear water flows out the outside pipe. I use a simple device that fits into the condensate pipe and attaches to the hose. Here is a link to the device. Very easy to use, and you know the drain line is clear.
