There are a number of forms of salt produced for consumption (and by default, housekeeping!): unrefined salt (such as sea salt), refined salt (table salt), and iodized salt. Kosher salt is sodium chloride processed to have flat crystals.

Maids2000 TIPS:

General cleaning… Salt works as an effective yet gentle scouring agent. Salt also serves as a catalyst for other ingredients, such as vinegar, to boost cleaning and deodorizing action.  For a basic soft scrub, make a paste with lots of salt, baking soda and dish soap and use on appliances, enamel, porcelain, etc.

Save the bottom of your oven…
If a pie or casserole bubbles over in the oven, put a handful of salt on top of the spill. It won’t smoke and smell and it will bake into a crust that makes the baked-on mess much easier to clean when it has cooled.

Clean sink drains…
Pour salt mixed with hot water down the kitchen sink regularly to deodorize and keep grease from building up.

Remove water rings…
Gently rub a thin paste of salt and vegetable oil on the white marks caused by beverage glasses and hot dishes, on wooden tables.

Clean greasy pans…
Cast-iron skillets can be cleaned with a good sprinkling of salt and paper towels.

Clean stained cups…
Mix salt with a dab of dish soap to make a soft scrub for stubborn coffee and tea stains.

Clean refrigerators…
A mixture of salt and soda water can be used to wipe out and deodorize the inside of your refrigerator.

Clean brass or copper…
Mix equal parts of salt, flour and vinegar to make a paste, and rub the paste on the metal.  After letting it sit for an hour, clean with a soft cloth or brush and buff with a dry cloth.

Clean rust…
Mix salt and cream of tartar with just enough water to make a paste.  Rub on rust, let dry, brush off and buff with a dry, soft cloth.  You can also use the same method with a mix of salt and lemon.

Clean a glass coffee pot…
Every diner waitress’ favorite tip: add salt and ice cubes to a coffee pot, swirl around vigorously, and rinse.  The salt scours the bottom, and the ice helps to agitate it more for a better scrub.
