Since all of us always have many things in the kitchen as well as the fridge to keep us going, we miss out on throwing away the ones that aren't needed or old or expired. And this is what takes up the space or spreads bad odour and in turn spoils the other foods around them as well. So make sure you keep your fridge organized and leftovers fresh in order to keep a healthy home environment.
Old baking powder can actually end up ruining your baked goods. Once you open up the baking powder, the moisture from the air can affect the quality of it. And with time, this can lead to baked goods that don't rise properly or just doesn't taste as great. When you store baking powder correctly, it can last up to six months to a year. But if you've had a carton for longer than that, you need to check on it and throw it away if need be.
The sponge that you use to clean your dishes and kitchen sink could also be harboring harmful bacteria. Most of the people know when to throw away the used sponge time to time. It is when it starts to smell and look worse. But ideally, experts recommend replacing the old ones with the new ones every two weeks or so. If you're not able to change your kitchen sponge that often, make sure you clean your dishes with something else that's easily washable or replaceable.
Opened bottles of wine can actually become flat or oxidized sooner than later. Once you open the win bottle, it is always important to re-cork it and put it in the fridge so as to slow down the oxidation process spurred by exposure to light, heat and oxygen. Most wines will last for a few days only once you open them. If the wine begins to develop a brown tinge or have a white-vinegar and bruised-apple smell, you should know you need to toss it.
