Stuff to donate but where?

I have mounds of stuff, from kitchenware to unopened food (tons of boxes of new Arm & Hammer baking soda, anyone bake?) to cleaners to many dozens of electric mosquito rackets, that I'd like to donate to the right charity or ngo in Hanoi this weekend. But no clue where that might be. Suggestions?

There is a group call "Help Hanoi's Homeless" which collect used stuff to give to homeless people in Hanoi.
I will PM you contact info of someone there
(since I guess I'm not allowed to post here)

It's great for cleaning too, since one product I have  been trying to buy - an Ajax-type powder-cream cleanser for cleaning grouting, tiles and sinks, doesn't appear to be widely available here. Forgive me for irrelevant intrusion on your donation post. 🙂
