Which cleaning products can pinch hit for others?

The average home today has a bewildering array of specialized cleansers meant for this, that or the other typical personal hygiene or household cleaning task. There is certainly the original mainstay of cleaning, soap. Then there is dish liquid. There is one or more laundry detergent. Perhaps a body wash. Hair shampoo. Ajax™ or Bon Ami™ or some such abrasive cleanser. Drano™ or one of its fellow drain cleaners. Tooth paste. Mouthwash.

Clearly these products, while all meant for some form of cleaning, are not entirely interchangeable. Listerene™ won’t do much good in a clogged drain and one would certainly not want to gargle with Drano™. But many cleaning products can, when some other cleaner is not available, be put in to pinch hit. A pure bar soap like Ivory™, for instance, may not taste very good but it does a decent job of replacing toothpaste. However it leaves a film on fine crystal and clothing, and so doesn’t work well for dish liquid or clothing detergent. Which ones can pinch hit, and for which other products?
