Sometimes in our life, emergencies do happen.  What will you do?  The secret is, don't panic.  But here, I am not referring to emergencies that are lives threatening.  Only emergencies like, you are out of deodorant or mouthwash and you have no more time to buy because you are in a hurry.  There are alternatives for these things.  For sure every household has vinegar, baking soda and other household items. Here are the things that you can do:

Suddenly one morning after taking a shower, unexpectedly your deodorant spray or roll-on is emptied. There is nothing to worry because you can use white vinegar as your deodorant. Yes, just splash a little white vinegar under each arm and let it dry. Or if you don't want vinegar, try applying a small amount, about a teaspoon's worth, of baking soda with a powder puff under each arm. That's it, it will keep your underarms smelling fresh the whole day.

Sprinkle some salt in your toothbrush and brush your teeth just like the normal way you brush it. Then after brushing thoroughly, rinse your mouth with water. Your teeth will be effectively clean just like using the ordinary toothpaste

Vinegar can be use also as mouthwash. After eating a spicy meal and you want to freshen your breath but you are out of commercial mouthwash, here is what you will do. Rinse your mouth with a solution made by dissolving 2 tablespoons apple cider vinegar and 1 teaspoon salt in a glass of warm water. Also if you want, try gargling with 1-teaspoon baking soda in a half glass of water. The baking soda will neutralize the odors on contact.

If you are outside in your house doing some grilling and mosquitoes and other insects are in feast with you and you have no more anti-inch cream or solution in your medicine cabinet, no problem. To instantly stop the itch of mosquito bites or other insect bites, dabbed the area with a soft cloth or a cotton ball saturated with white or apple cider vinegar. Do this also to rashes caused by exposure to poison ivy.

Yes I have tried all these stuff and they are all effective.  If it works on me, I am sure it will work on you. If emergency arises, try it!
