Just four examples I came across online:

Most shampoos and conditioners...
...preventing silver from tarnishing
...softening your feet
...preventing shoes from squeaking
...covering up scratches on wodden furniture.

Alka-Seltzer...
...cleaning toilet bowls
...unblocking sinks and drains (I find that boiling water is very effective though)
...soothing insect bites.

Powdered milk...
...cleaning silver
...mix with water and add dye to make paint (I'm sure it would be far cheaper though just to buy the paint in the first place.)

Any brand of toothpaste...
...fills cracks and small holes in plaster, prior to decorating.
