I too use baby wipes when I get to work. I carry a messenger bag with a change of clothes, shoes & lunch. I keep makeup at work. I tried panniers, but the wind blows here more often than not and the bag is more streamlined. I liked the panniers because my back is usually sweaty when I get to work and I tried to tell myself that working against the wind will make me stronger, but I usually go for easier! I just make sure that I have about 10 minutes to stop sweating.
