Why not try it out and see? Try dumping a gallon of boiling water
down the sink to clear it out. I do that every time I make
spaghetti, and this keeps my kitchen drain clear.

Couple that with the caustics of dishwashing detergent and you will have a
pretty clean drain.

If you have a mechanical problem, such as long runs without enough pitch,
spouses that dump large amounts of bacon fat in the drain, it may take a bit
more to keep them free flowing.
