And if youve got an electric toothbrush that allows you to swap out the brush head?

Give the handle a wipe down each time you do so.

Problem is, loofahs and sponges tend to hang onto some nasty stuff.

Oh, and major bacteria.

Were talking serious infection-causing bugs like Staphylococcus, per an olderJournal of Clinical Microbiology1study.

Replace natural sponges at least once a month and loofahs every six to eight weeks, Wilson recommends.

If you want togive it a quick cleanevery week or so (a good idea!

), pop it in the microwave for 30 seconds, she suggests.

The high heat will kill off any germs.

Its Amazing How Its All Connected.

Your razor

Its totally understandable to want to stretch the life of your razor.

But they can also harbor bacteria like Staphylococcus, notes a study conducted byMicroban.

And the longer you let them hang around, the more germy they become.

What to do:Give yourself a fresh razor every five to secen shaves, Wilson recommends.

Not only is it cleaner, but youll also get better results in the hair-removal department.

The alcohol acts as a disinfectant.

The soap dish

Doesnt the soap keep it clean?

Its always damp, and its got soap scum hanging around, Wilson says.

Which isnt just gooky and gross.

What to do:No need to actually replace your soap dish.

Hand and face towels

In the habit of washing these once a week?

Thats actually not enough, Mock says.

They can harbor bacteria from moisture and daily repeated use, she explains.

Use the hottest possible washer and dryer parameters, c’mon.

Heat is your best bet for eliminating germs, she adds.

And attempt to get a new one every six months.

The shower curtain liner

The green, black, and pink spots youve been ignoring for…ever?

(But still replace it at the recommended intervals!)
