Spring is just around the corner…get a head start with Business Insider‘s list of the bathroom items you should get rid of:

Old cases for your contact lenses  Bacteria from your hands gets in there and it’s very difficult to get them totally sterile again.  Buy a new one every three months.

Cosmetics that have changed color, odor or consistency  The oil in them can go bad and start to grow bacteria.

Acne products that have been open for a while  The kinds with benzoyl peroxide or salicylic acid decay pretty quickly.  They’re only good for about 4 to 6 months after you open them.

The bottle of rubbing alcohol or hydrogen peroxide you bought years ago  They don’t go bad but they lose potency.  Look for the expiration date on the bottle.

Expired medications  A Harvard study found 90% of them are still safe and relatively effective even 15 years after they expire…but a few you should NEVER use past their expiration date are insulin, liquid antibiotics, certain heart medications or anything else with nitroglycerine in it.
