I use baking soda/white vinegar all of the time. Here are a few of the ways I use it often.
I use non-stick pans. When I make eggs, for example, I use barely any oil at the bottom of the pan and I am left with fried-on sticky mess that I used to find impossible to clean without a ton of elbow grease. Now, I coat the pan in baking soda, add a little water and put on stove to heat to about a boil. I let the pan cool slightly, then use dish cloth to wipe out the mess....it comes right out and the pan is sparkling clean.
I use baking soda as scouring agent (like how some use Comet). I sprinkle in bathtub, kitchen sink, stove top etc. Sprinkle with water to form paste, let it sit for a bit and scrub clean.
I use vinegar and water for my floors.
I use white vinegar instead of downey and the like in washer for towels, linens etc to make them extra soft and fluffy.
I found that water/grease marks in wood will come out with vinegar/water. Just pour on mark, let it sit and wipe clean.
Vinegar will remove soap scum/water marks from faucets.
I've removed ketchup stains from clothing by blotting the stain in vinegar and scrubbing with a damp cloth sprinkled in baking soda,
