Vinegar is a popular, tangy ingredient for many recipes, but it is also a well-known cleaning product around the house. Vinegar is very useful as an ingredient that kills germs, removes odors and cleans stains.
For cooking, vinegar is popular as a main ingredient in items such as salad dressing and for pulled pork. It has also been used for aesthetic reasons, such as keeping fish white while it is cooking. It is a popular ingredient for marinades because the acids in vinegar help break down meat, making it tender.
As a cleaning ingredient, vinegar can be used as a disinfectant around the house. If combined with baking soda, it can be used to whiten ceramics or clean coffee pots. It can remove mildew as well as lime buildup on faucets.
