I keep a microfiber wipe and a bottle of glass cleaner in each bathroom. I have several in my house, so I alternate which ones I use throughout the day. This way, I am in each bathroom at least once. While I am in there, I use the rag and glass cleaner to wipe down the mirror and sink. It takes less then 60 seconds, and the sink and mirror are always clean that way. I also keep disinfecting wipes by each toilet and wipe it down too. This all takes less than 2 minutes to do, and helps reduce the spread of colds and flu too! I find that half the battle in simplifying is a having the tools you need at hand when you need them!
