Medicines: Never store any medicines beyond the expiry date mentioned on the pack.
Kitchen Sponges: These are high bacteria zones that should not remain in your kitchen for over a month at the most. You should also try to keep the bacteria at a low level by disinfecting your sponges every day with a disinfectant. You can also microwave the moist sponges to kill the bacteria.
Sports Bra: Chuck your sports bra out as soon as it begins to feel "too comfortable". So if the elastic is not firm enough or if you notice holes in the garment, throw it out because it is not giving you the support you need.
Tampons: If you do not use them too regularly, you may have to throw them out as soon as the wrapper looks even a little damaged. If the wrapper is broken or damaged, it probably means that the cotton inside may be infected with bacteria.
Chopping Boards: Like the kitchen sponge, this is another item that stores bacteria. So to clean it, disinfect with liquid chlorine bleach. Toss it when it develops crack or other signs of wear.
Condoms: Usually condoms have an expiry date mentioned on them. But if you have kept the condoms in too hot/too cold environment like your wallet or the fridge, it is better to throw them away as soon as the wrapper looks a little damaged.
Sneakers: If you wear your sneakers once in every 3-4 days, they should last you for about an year. But if you run regularly, they should be replaced every 5 months to maintain the protection for your feet.
Make Up: Toss your creams and paints if it has not been used up in the last 8 months. Even though it is all expensive stuff, you don't want to harm your skin with products that may have deteriorated in quality.
Toothbrush: Dentists advise that the toothbrush should be replaced every six months. Replace it sooner if you notice the bristles to be frayed.
