Here's a tip: salt, baking soda, and vinegar

During my spring hausfrauing, I came across helpful household hints books for salt, vinegar, and baking soda. I'm planning a potions post soon - I make a lot of my own cleaning products - but I wanted to retain this info and figured I'd share it here in case you guys could use it too. I don't typically use salt, but I use baking soda and vinegar a lot (even though MFD is constantly complaining about the smell and comparing it to a Summer's Eve, if you catch my drift).

I hope you can save yourself some cash and incorporate these tips in your regular routines!

Thanks to Geege for being a photo prop.

• Any spill on the stovetop will come up more easily if sprinkled with salt first - the abrasive quality of salt removes the stuck on food but won't hurt the surface. 
• Those casserole dishes that won't come clean? Add boiling water and three tablespoons of salt. Let stand until the water cools, then wash as usual. 
• Exfoliate! While skin is wet, sprinkle salt in your hands and rub all over skin. Ain't nobody got time for dry skin. I am a very bad exfoliater. I need to do it more. 

• Keep baking soda in fridges and freezers to absorb odors. Change every three months. 
• Once a month, sprinkle carpets with baking soda, let sit overnight, then vacuum. I should do this. Dogs stink. 
• Remove mineral buildup and improve performance of your showerhead: Mix 1/2 cup baking soda and 1 cup vinegar in a sturdy plastic bag. Secure the bag around the shoewrhead with a rubber band so the showerhead is submerged in solution. Soak for one hour. Remove and run very hot water through the showerhead for several minutes. I am totally doing this this weekend. I pinned it eons ago. 
• Face scrub: make a past of three parts baking soda to one part water. Use as an exfoliating scrub. I do this and love it. 

• Sinks: Pour 1/2 cup baking soda through a funnel followed by one cup of vinegar. When the foaming subsides, flush with super hot tap water (I normally fill from another sink or the tub). Wait five minutes, then flush again with cold water. This clears blockages and washes away odor causing bacteria. For slow drains, pour in 1/2 cup salt followed by 2 cups of boiling vinegar, then flush with hot and cold tap water. 
• Keep frost at bay: Spray the outside of car windows with a solution of 3 parts white vinegar to 1 part water. I haven't tried this, but I will be trying it this winter. 
• Microwave: place a glass bowl filled with 1/4C vinegar and 1C water inside. Microwave for five minutes. Once it cools, dip a cloth into the liquid and use to wipe interior. Splatters will be loosened and come up quickly. I add a little squirt of lemon juice to the bowl too. 
• Pour 1 cup undiluted vinegar into the bottom of your dishwasher once a month and run the machine through a full cycle without dishes or detergent. 

I know there are 459,872 uses for each. How do you use them, or what on this list will you try?
