The bathroom has its own particular type of clutter but a rose by any other name, as the saying goes.
Bathroom clutter is usually more specific than that found in other rooms. It is not known to be diverse. It usually comes in the form of toiletries, medicines, towels and the like. Apart from the occasional motorcycle collection, that’s about it. As far as the toiletries go, you may have a medicine cabinet or a linen closet where you store them. These rules of thumb and forefinger apply to either storage place.
Weed out your toiletries. (And use weed killer, if necessary.)
Sort everything out by eliminating from a big pile or do section-by-section or drawer-by-drawer if the task appears too overwhelming for one session. There are probably a lot of bottles and the empty ones are an easy decision: throw them out. (Do not pass go; do not collect $200 dollars. Just throw them out!) Keeping old medicine bottles is a no no.
Under the sink may be a few mystery items. Don’t bother trying to figure out what they are or what they want. Hold them to your nose and if they smell, get rid of them (Your in-laws and other relatives will not pass this test.) Full bottles should be stored in full view and in all probability, most of the empty ones will be tossed. Do not delay your mission to de-clutterize the bathroom by inner questions like: what is this stuff anyway? And why is it purple? Throw it out before it has a chance to multiply. Keep the things you use most often up front so that you have easy access to them.
