Salt and Vinegar: a non-toxic way of cleaning

Greenfootsteps , an online green journal suggests the following household tip:

Salt can be mixed with vinegar to create a good general purpose cleaner. Don't use it on waxed surfaces, marble or linoleum because the vinegar may be too strong for the surface and cause damage. This vinegar and salt mix can be used for general cleaning about the house. Swab down surfaces and clean inside the fridge and cupboards with it.

It will also remove tea and coffee stains from cups and teapots, etc.

Glass and tiles will come up shining from washing with a salt and vinegar solution.
