Ever since we moved in, we have utilized two cabinets in two bathrooms for our personal hygiene/medicine stuff, in addition to a bin for our daugher's things. This has led to a bit of disorganization, with bandaids being in one bathroom and something else being in another and where is the thermometer?
The pre-Pesach cleaning time is a good opportunity to solve this problem and organize things. It really doesn't take more than a few minutes (or at least, it shouldn't). I removed expired medications, organized all the different types of bandaids in one location, moved all of the non-essentials together, and basically coralled everything together in a logical format which makes the cabinet work for me instead of against me (hello more space!). I bought a set of two plastic trays at Walmart for 75 cents. Cheap and useful!
It's a good time to take inventory, update the first-aid kit, get rid of the old stuff, and see what you really have so you can use it up instead of always buying new (where applicable). See - cleaning can be fun!!
