Salt is an excellent cleaning agent, by itself or in combination with other substances.
No Drip candles
If you soak new candles in a strong salt solution for a few hours, then dry them well, they will not drip as much when you burn them.
To fill nail holes, fix chips or other small dings in white sheetrock or plaster walls, mix 2 tablespoons salt and 2 tablespoons cornstarch, and then add 5 teaspoons of water to make a thick paste. Use the paste to fill the holes.
On sidewalks and driveways
This is one of the oldest uses of salt. Lightly sprinkle rock salt on walks and driveways to keep snow and ice from bonding to the pavement and allow for easier shoveling and scraping. But don’t overdo it; use the salt sensibly to avoid damage to plants and paws.
Control a barbeque
Sprinkle a little bit of salt on flames from food dripping in barbecue grills to reduce the flames and calm the smoke without cooling the coals as water does.
A solution of salt and turpentine restores the whiteness of enameled bathtubs and lavatories.
Pour strong brine down the kitchen sink to prevent grease from collecting and causing bad odors.
Remove white marks
A thin paste of salt and salad oil removes white marks caused by hot dishes or water from wooden tables.
Make play dough
Use 1 cup flour, 1/2 cup salt, 1 cup water, 2 tablespoons oil and 2 tablespoons cream of tartar. Stir together flour, cream of tartar, salt and oil, and slowly add water. Cook over medium heat stirring frequently until dough becomes stiff. Spread onto wax paper and let cool. Knead the dough with your hands until it reaches a good play dough consistency.
Extinguish grease fires
Keep a box of salt near your stove and oven, and if a grease fire flares up, throw salt on the flames. When salt is applied to fire, salt absorbs the grease and cuts off the oxygen supply. Caution: A grease fire is very different from a regular fire. Never use water on grease fires; it will splatter the burning grease.
