Vinegar is an acid, and baking soda is a base. Thus, if you mix them together, you will get an acid-base reaction. Vinegar is probably the most common way to activate baking soda.. The reaction can turn the baking soda into a powerful cleaning agent. For example, vinegar and baking soda can be used to clean a kitchen sink. Add cup of warm tap water and 2 tablespoons (29.6ml) of vinegar into cup of baking soda to see if the baking soda is still good. If it bubbles, it is. This is called "proofing" the baking soda. Vinegar will create a powerful fizz when added to baking soda because of the degree of acidity in it. It's the acetic acid in the vinegar that causes the chemical reaction. Lemon or lemon juice will create an alkalizing effect when mixed with baking soda, activating it. Add a teaspoon of baking soda to a glass of mineral or other water, and add in the juice from half a lemon. Mix thoroughly before drinking. Some recipes call for adding peppermint leaves or a pinch of salt into the lemon and baking soda mixture, in addition to water. This mixture has purported health benefits. Some people believe it can be used to combat acidosis. The mixture helps the body remove toxins and burn fat. It can be helpful for kidney care. Drinking lemon juice and baking soda can also improve your digestion and combat acid reflux. It helps to purify your liver and provides some needed nutrients, like vitamin C. Always check with your doctor, though, before using any natural remedies. Although lemon juice is one of the most common acids to add to baking soda, other juices can work too. Try adding orange juice to baking soda, and you will get bubbles that come from the release of the carbon dioxide. Fruit purees also activate baking soda. Orange juice has more acid in it than most other fruit juices. Other juices that will react to baking soda include grape juice, vegetable and fruit juice blends, and limeade. Ketchup can react with baking soda because it contains vinegar. The acidic reaction will cause fizzing that indicates the baking soda is fresh and actively working.

Summary: Add vinegar to baking soda. Add lemon to activate baking soda. Add other juices to baking soda.

For this method, you will need access to a handful of household supplies, including dish washing liquid or dish soap, running water, and a clean, dry, lint-free cloth. Avoid dish washing liquid that contains lotion, as this can cause streaks or stains on your glasses. Remember some dish washing liquids are abrasive and can damage coatings on the lenses of your glasses, such as anti-reflective coating. Wash your hands well with water and soap so your hands are free of any dirt or debris that could get on your glasses. Then, take your glasses and hold them under warm running water. This will help to remove dust and debris on the lenses. This way, you are not at risk of seriously scratching your lenses when you clean them with the dish soap. Make sure you use warm or lukewarm tap water. Hot water can damage the coating on some lenses. You may apply one to two drops of the dish soap to your fingertip and then gently place it on each lens. Try to only use a small amount, as dish soap is very concentrated and a little will go a long way. Once the dish soap is on the lens, use your fingers to gently rub both sides of the lens. Do this for a few seconds. Try to rub away any stains on the lens using the soap and the water. You may also wash the nose pads, the temples, and arms of the glasses. These areas can accumulate dirt and debris so it may be a good idea to clean them. Once you have cleaned the glasses thoroughly and removed the stains, wash the soap off well. Use warm running water to do this. Try to get all of the soap off as any leftover soap may smear when you try to dry the lenses. Always dry the glasses well after you clean them. Use a clean, dry, lint-free cloth to wipe them off. Dry the lenses in a circular motion, making sure you remove all the water on the lenses as you do not want the water to dry and cause further water stains. You may try using a microfiber cloth to dry off the lenses. No matter what type of cloth you use, make sure it is soft as you do not want to scratch the lenses when you dry them off. If you launder the cloth, do not use fabric softener or dryer sheets when drying, as this can cause streaking on the lenses.
Summary: Gather your supplies. Rinse your glasses under warm water. Apply a drop of dish soap to the lenses. Wash off the dish soap. Dry the glasses with a clean, dry, non-abrasive cloth.
