Just some general bathroom help is if you just keep a, you know, your disinfectant and an all-purpose cleaner and a rag just in every bathroom, but specifically the guest bathroom. That way you can just go in and tidy up when unexpected guests come. It’s kind of easier to get away for a minute if you already have the supplies in there.
To help keep your bathroom smelling fresh, you can always get a fabric softener sheet and just put it in the bottom of the wastebasket, replace it about once a week. This also helps in drawers, cars, basically anywhere in the house to help keep things fresh.
