For clogged up kitchen drains, I pour a cup of baking soda down the drain followed by some vinegar....when that stops bubbling, I pour boiling water down the drain. If you do this once a month, NO CLOGS! It works like magic...

Now I'm wondering if a baking soda/vinegar solution would take the "smoke" stain off of the INSIDE windshield of my car....anyone know? It is an old car ('98 Toyota) and the previous owner was a smoker. At night, holy cow! You can hardly see out of it. Forget Windex or any of the other cleaners. They don't cut it (pun intended).
